Features
Taper Grip® Bushing System
The keyless Taper-Grip® bushing system provides simple and reliable installation without the need for a custom shaft.
Ductile Iron Housing
New ductile-iron housing is twice as strong as cast iron, making it one of the most rugged bevel gearboxes available
Increased Overhung Load Capacity
Cyclo® BBB4 has over 375% overhung load capacity than previous models
Increased Ratings
The newly designed Cyclo® BBB4 series has been optimized for increased power ratings over the previous generations
New Larger Size
New F Size yields higher torque and can accommodate larger shaft diameters
New Ratios Available
46 standard and 87 optional ratios added
Unified Lubrication System
Single oil-bath lubrication system for easy maintenance and higher performance.
Compact Design
The most torque-dense right-angle gearbox design available in the industry. The new ductile-iron housing allows for higher radial load in a small, compact design.

FAQ
Do you have questions about the Cyclo® BBB4? Below are some of our most commonly asked questions, or you can view our Support area under Knowledge for more frequently asked questions and answers.
What are service factors and how are they used?
In general, reducers and gearmotors are rated for specific conditions and operating requirements of the application by the use of AGMA-defined Service Factors. There are three AGMA load classifications for reducers: uniform (U), moderate shock (M) and heavy shock (H), and three AGMA load classifications for gearmotors: I, II, and III. Refer to our catalog for a list of AGMA load classifications. These Service Factors are used in the product selection process to adjust for the specific conditions and operating requirements of your application.
What are the advantages of the new Steel Taper-Grip® bushing?
With an increased torque capacity, the new Steel Taper-Grip® bushing can be used in reversing and/or high start-up applications. The new Steel Taper-Grip®bushing can be used on all Taper-Grip® products.
What are the advantages of the Taper-Grip® bushing?
The Taper-Grip® bushing is integral to the Cyclo® BBB4 and provides for easy mounting and removal to and from the shaft of the driven machine. Because it requires no key way, the shaft isn’t weakened and maximum torque is transmitted.
What thermal capacity limitations does the Cyclo® BBB4 have?
The Cyclo® speed reducer, by virtue of its smooth, almost frictionless operation (unlike traditional helical gears), has a thermal rating that far exceeds its mechanical capacity and all but eliminates the conventional limitations due to heat.
