RB3010 RB3010UUCC0 Crossed Roller Bearing Industrial Robot Bearing 30x55x10mm with ISO9001

The RB3010 Crossed Roller Bearing (30x55x10mm) is a compact, high-rigidity precision bearing designed for industrial robot arms and automation equipment. Models include RB3010 (open type) and RB3010UUCC0 (double sealed type with preload).

With cylindrical rollers arranged alternately at 90° between the inner and outer rings, the RB3010 series can simultaneously support radial loads, axial loads, and moment loads. Its thin-section design makes it ideal for space-limited robotic joints and precision rotation systems.

Manufactured under ISO9001 quality management standards, this bearing ensures consistent dimensional accuracy and stable performance in demanding robotic applications.
