THK RB3510UUCC0 Cross Roller Ring
The RB3510UUCC0 is a basic‑type crossed roller bearing designed for high‑precision inner‑ring rotation. It features a separable outer ring (split for easy mounting) and an integrated inner ring, with cylindrical rollers arranged orthogonally in 90° V‑groove raceways via precision spacer retainers.
The RB3510UUCC0 is a basic‑type crossed roller bearing designed for high‑precision inner‑ring rotation. It features a separable outer ring (split for easy mounting) and an integrated inner ring, with cylindrical rollers arranged orthogonally in 90° V‑groove raceways via precision spacer retainers. This design enables simultaneous support for radial, axial, and moment loads, delivering exceptional rigidity in a compact form factor. Factory‑configured with double rubber seals (UU) and normal internal preload (CC0), it ensures stable low‑torque rotation and reliable contamination resistance for precision machinery applications.

Key Design Features
- High Rigidity & Compactness: Crossed roller arrangement with spacer retainers provides 3–4× the rigidity of conventional double‑row thin angular contact bearings in a slim profile.
- Multi‑Load Capacity: Single bearing supports radial, axial, and moment loads simultaneously, simplifying system design.
- Stable Low Torque: Spacer retainers eliminate roller skewing and friction, ensuring consistent, smooth rotation even under preload.
- Contamination Resistance: UU double seals prevent ingress of dust, chips, and coolant, extending service life in industrial environments.
- Easy Installation: Separable outer ring simplifies mounting and alignment; assembly screws maintain ring integrity during installation.
- Precision Preload: CC0 standard preload eliminates internal clearance for high‑repeatability positioning.
Typical Applications
- Precision rotary tables for small machine tools and measuring instruments
- Industrial robot joints and end‑effector rotary stages
- Semiconductor manufacturing equipment (wafer handlers, inspection tools)
- Medical diagnostic and imaging equipment
- Optical positioning systems and precision automation modules
