So, you’re hunting for a Bonfiglioli gearbox cross-reference guide, huh? It’s a common quest when you need a replacement or are looking to swap out an existing unit for a new one. The good news is, it’s definitely doable. Think of a cross-reference guide as a translator – it helps you figure out what Bonfiglioli model corresponds to another manufacturer’s gearbox, or even a different Bonfiglioli series if your original is no longer current. This can save you a whole lot of head-scratching and, more importantly, downtime.
Why You Might Need a Bonfiglioli Gearbox Cross-Reference
You’ve probably already got a reason in mind, but let’s lay it out clearly. Sometimes, the gearbox you have installed isn’t specifically a Bonfiglioli. Maybe it’s a competitor’s brand, and you’re considering switching to Bonfiglioli for their reputation, availability, or specific features. Or perhaps you have an older Bonfiglioli unit, and you need to find its modern equivalent because the original is obsolete or difficult to source.
Replacing an Existing, Non-Bonfiglioli Gearbox
This is where cross-referencing shines. Imagine a critical piece of machinery in your plant has a gearbox from a brand that’s discontinued, or their support is lacking. You’ve identified Bonfiglioli as a viable alternative, but how do you match the specs? A cross-reference guide can take your current gearbox’s parameters – mounting, shaft size, ratios, power rating, motor frame size – and point you towards the closest Bonfiglioli equivalent. It’s about finding a seamless fit without having to redesign your entire system.
Upgrading or Replacing an Obsolete Bonfiglioli Unit
Even Bonfiglioli evolves. New series are introduced with improved efficiency, better sealing, or enhanced features, while older models might be phased out. If you’re servicing a machine with a vintage Bonfiglioli gearbox, you’ll likely need to find its current counterpart. This ensures you get access to the latest technology and readily available spare parts, keeping your machinery running smoothly for years to come.

The Anatomy of a Bonfiglioli Gearbox in Cross-Referencing
To effectively use a cross-reference guide, you need to speak the language of gearboxes. It’s not just about ‘a gearbox’; it’s about understanding the specific details that define it. Whether you’re looking at your existing unit or searching for a Bonfiglioli replacement, these are the key characteristics you’ll need to identify.
Mounting and Footprint
This is arguably one of the most critical factors. How the gearbox attaches to your machine is paramount. Is it a flanged mount? A foot-mount? What are the bolt hole dimensions and positions? Bonfiglioli offers a wide array of mounting configurations, from standard B5 or B14 flanges to custom solutions. A cross-reference needs to match these physical dimensions precisely to ensure the new gearbox bolts up without fabrication.
Flanged Mounts (e.g., B5, B14)
These are common for direct motor mounting. The flange on the gearbox connects directly to the motor’s mounting face. Identifying the specific flange type (like IEC B5 or B14) and its diameter and bolt circle is essential.
Foot Mounts
Here, the gearbox has feet that attach to a base. The spacing and size of these feet are what you’ll need to cross-reference.
Shaft Dimensions and Configuration
The output shaft of the gearbox needs to connect to your driven equipment. This means looking at its diameter, length, keyway dimensions (if applicable), and whether it’s solid or hollow. Getting this wrong means your new gearbox won’t be able to transmit power to your driven machinery.
Solid Shafts
These shafts have a specific diameter and often a keyway to lock onto couplings.
Hollow Shafts
These can be shrink-fit (fitting over a shaft) or bore and keyway, allowing a shaft to pass through.
Gear Ratios
This determines the speed reduction or increase between your input and output. If your application requires a specific output speed, you’ll need to find a Bonfiglioli gearbox with a corresponding ratio. Gearboxes can have single, double, or even triple stages, each contributing to the overall ratio.
Single Stage Ratios
Offering a specific range of reduction.
Multi-Stage Ratios
Achieved by combining multiple gear sets for greater reduction.
Power Rating and Torque
Can the Bonfiglioli gearbox handle the load? You’ll need to know the power (in kW or HP) your motor is delivering and the torque (in Nm or lb-in) required by your driven equipment. The cross-reference should ensure the new Bonfiglioli unit has sufficient capacity to avoid overheating or failure.
Motor Power Input
The power delivered by the motor driving the gearbox.
Output Torque Capacity
The rotational force the gearbox can deliver at its output shaft.
Mounting Position and Orientation
Gearboxes can be installed in various orientations: horizontally, vertically, or at an angle. The internal lubrication system is designed for specific positions. A cross-reference should confirm that the Bonfiglioli equivalent can operate reliably in the required mounting orientation.
Where to Find Bonfiglioli Gearbox Cross-Reference Information
The official Bonfiglioli documentation is your primary resource. Don’t underestimate the power of their product catalogs and technical manuals. They are meticulously designed to help you choose the right product.
Bonfiglioli Official Catalogs and Technical Manuals
These are the gold standard. Bonfiglioli publishes detailed catalogs for each of their product lines (e.g., CILNDER, HILOW, PLANETARY). Within these, you’ll find tables and selection guides that often include equivalent models or specifications that allow for direct comparison. Look for sections that detail dimensions, performance data, and mounting options.
Product Series-Specific Catalogs
Each gearbox series has its own detailed publication.
Selection Tools and Software
Bonfiglioli might offer online tools or software to help with gearbox selection, which can indirectly act as a cross-referencing tool by showing available configurations.

Common Cross-Reference Scenarios and How to Approach Them
Let’s get practical. What do these cross-references actually look like in the wild? Understanding common scenarios will help you map your needs to the right Bonfiglioli solution.
Cross-referencing Competitor Brands to Bonfiglioli
This is a frequent scenario. Let’s say you have a Nord F Series helical gearbox and want to switch to a Bonfiglioli. You’d gather the critical data from your Nord gearbox: mounting type (e.g., foot mount, flanged), shaft size, center distance, gear ratio, and motor frame size. Then, you’d consult Bonfiglioli’s equivalent product series (likely their CILNDER or HILOW series for direct replacements) and start matching these parameters. Some distributors might even have specific charts for common competitor cross-references. For instance, a Nord NT3 is often directly comparable to a Bonfiglioli CILNDER.
Matching Footprint and Mounting Interfaces
Ensure the bolt hole patterns and overall dimensions are compatible.
Reconciling Gear Ratios and Shaft Specifications
Find a Bonfiglioli unit that offers the same or a very similar ratio and has compatible shaft dimensions.
Replacing Older Bonfiglioli Models with Current Equivalents
Gearbox technology doesn’t stand still. If your machine has an older Bonfiglioli gearbox, say from their original ‘A’ series helical bevels, and you need a replacement, you’ll be looking at their current offerings – typically the CILNDER (helical inline) or HILOW (helical bevel) series. The challenge here is that older models might have slightly different mounting dimensions or shaft designs. You’ll need to:
Identifying Obsolete Model Numbers
Often found on the gearbox nameplate.
Consulting Bonfiglioli’s Obsolescence Matrices or Equivalent Tables
These are specifically designed to guide users from older to newer product lines. For example, an older NRV unit might have a direct modern equivalent in the CILNDER series. You’ll look for specific series codes and size numbers to make the connection.
Understanding Bonfiglioli’s Gearbox Naming Conventions
Bonfiglioli uses a systematic naming convention for their gearboxes, which is very helpful for identification and cross-referencing. Breaking down these codes is key to understanding what you have and what you need.
Decoding Model Numbers (e.g., CILNDER, HILOW, PLANETARY)
- CILNDER Series: These are helical inline gearboxes. The naming might look like CILNDER 80/112-2 or similar, indicating the main housing size and the number of stages.
- HILOW Series: These are helical bevel gearboxes. A typical name might be HILOW 71A2, where ’71’ is the size and ‘A2’ indicates the number of stages.
- PLANETARY Series: For planetary gearboxes, the naming convention focuses on torque, size, and ratio configurations, for example, 300P3-78-73.
Interpreting Size Codes and Stage Indicators
The numbers and letters within the model name signify critical parameters like motor flange size, housing dimensions, and the number of gear reduction stages. For instance, a larger number usually means a larger, more powerful gearbox.
For those seeking comprehensive information on gearbox solutions, the Bonfiglioli Gearbox Cross Reference Guide is an essential resource.

Practical Steps for a Successful Cross-Reference
Don’t just jump in blindly. A structured approach will save you time and potential headaches.
Gather All Information from Your Existing Unit
This is non-negotiable. Before you even look at a Bonfiglioli catalog, you need a complete picture of the gearbox you’re trying to replace.
Nameplate Data: Manufacturer, Model Number, Serial Number
The nameplate is your starting point. Even if it’s a competitor, all the manufacturer’s identification will be there.
Physical Dimensions (Mounting Pattern, Shaft Size, Overall Length/Width)
Measure everything carefully. Take photos. Your measurements are crucial.
Gear Ratio(s) and Input/Output Speeds
If you know the motor’s RPM and the driven equipment’s required RPM, you can calculate the ratio.
Power Rating or Motor Frame Size
This helps determine the required capacity of the replacement gearbox.
Consult Bonfiglioli’s Documentation and Online Tools
Once you have your data, it’s time to use the resources.
Search Bonfiglioli Catalogs for Equivalent Specifications
Look for models that match your collected data point-by-point.
Utilize Distributor-Provided Cross-Reference Tools
Many distributors have their own internal databases or simplified charts for common conversions.
Verify with Bonfiglioli Technical Support or a Distributor
This is your safety net. Never assume you’ve got it right.
Submit Your Data for Confirmation
Send your findings to a Bonfiglioli expert and ask them to verify.
Discuss Application-Specific Requirements
Sometimes, a direct substitution isn’t ideal. An expert can advise on slight modifications or alternative solutions that might offer better long-term performance.
Common Pitfalls to Avoid
Even with the best intentions, cross-referencing can go wrong. Knowing these common issues can help you steer clear of them.
Incomplete or Inaccurate Data
The most common mistake. If your measurements are off, or you miss a crucial detail, the entire cross-reference will be flawed. Double-checking everything is essential.
Ignoring Mounting Orientation Specifics
A gearbox designed for horizontal use might fail prematurely if used vertically without proper lubrication considerations. Always confirm the suitability for your mounting position.
Overlooking Service Factors and Duty Cycles
A gearbox might have the same power rating on paper, but if it’s not designed for the specific duty cycle (continuous vs. intermittent, shock loads), it won’t last. Bonfiglioli’s selection software often prompts for this.
In Conclusion
Finding a Bonfiglioli gearbox cross-reference isn’t about magic; it’s about meticulous data gathering and leveraging the right resources. By understanding your existing gearbox’s specifications thoroughly and consulting reliable Bonfiglioli documentation and expert assistance, you can successfully identify the perfect Bonfiglioli replacement. It’s about ensuring your machinery keeps running efficiently and reliably, minimizing downtime and maximizing productivity. Don’t be afraid to dig into the specs and ask for help – that’s what these guides and experts are there for!
