The RB Series Crossed Roller Bearings are high-precision bearings specifically designed for industrial robots, robotic arms, and automation equipment requiring high rigidity, compact structure, and accurate rotation.
Models including RB2008, RB3010, RB5013, RB11015, RB15025, RB20030, and RB25040 feature a crossed roller structure in which cylindrical rollers are arranged alternately at 90° between the inner and outer rings. This design enables the bearing to handle radial loads, axial loads, and moment loads simultaneously.
RB series bearings are widely used in robot joints, rotary tables, harmonic reducers, and precision positioning systems.
Crossed roller structure for multi-directional load capacity
High rigidity and compact design
Superior rotational accuracy
Smooth motion with minimal friction
Capable of handling radial, axial, and moment loads simultaneously
Ideal for robotic arm joints and precision automation
| Model | Structure Type | Typical Application |
|---|---|---|
| RB2008 | Thin section crossed roller | Small robot joints |
| RB3010 | Compact precision bearing | Automation modules |
| RB5013 | Medium rigidity design | Robot wrist units |
| RB11015 | High load capacity | Industrial robot arm |
| RB15025 | Reinforced structure | Heavy-duty manipulators |
| RB20030 | Large size precision | Rotary platforms |
| RB25040 | High moment load support | Robot base rotation |
