Customized Crossed Roller Bearings for Robotic Applications

Every robotic joint and actuator can have different requirements for installation space, load, stiffness, rotational accuracy and mounting interface.

For this reason, a standard bearing is not always the most suitable solution.

Beining Technology provides customized crossed roller bearing solutions based on application requirements and mechanical drawings.

We can evaluate bearing solutions according to:

• Bearing dimensions
• Installation space
• Radial load
• Axial load
• Moment load
• Rotational speed
• Bearing clearance
• Runout requirements
• Mounting-hole configuration
• Sealing requirements
• Lubrication requirements
• Precision requirements
• Operating environment

Customers can provide a 2D drawing, 3D CAD model, existing bearing specification or basic application requirements for technical evaluation.

Our engineering team can then evaluate the application and recommend a suitable bearing configuration.
