RB30035 Crossed Roller Bearing
The RB30035 Crossed Roller Bearing is a precision bearing designed for applications requiring high rotational accuracy and rigidity within a compact design. Featuring a separable inner and outer ring structure, this model allows for easy installation and stable performance even under complex loading conditions.
Built with cylindrical rollers arranged orthogonally in a cross pattern, the RB30035 delivers smooth rotation and exceptional load-carrying capacity - supporting radial, axial, and moment loads simultaneously. This makes it ideal for use in robotic joints, rotary tables, machine tools, and semiconductor equipment where precise motion control is critical.

RB30035 Crossed Roller Bearing – FAQ
Ensure that the mounting surface is clean, flat, and burr-free. Verify the bearing's orientation and preload level before assembly. Avoid impact or forced installation to prevent damage to the rollers or raceways.
Use high-quality lithium-based grease for general industrial use. For high-speed or clean-room environments, special oil lubrication can be used. Periodic re-lubrication ensures stable performance and long service life.
Yes. Each RB30035 bearing can be supplied with a dimensional inspection report, material certificate, and accuracy test data upon request.
Each bearing undergoes 100% dimensional inspection, rotational accuracy testing, and noise/vibration evaluation before packing. Only qualified bearings are released for delivery.
