THK RE8016UUC0 Cross Roller Ring
RE8016UUC0 is an ultra‑thin‑type crossed roller bearing (Cross‑Roller Ring) from THK’s RE series, featuring a two‑piece (split) inner ring and one‑piece outer ring, optimized for outer‑ring rotation with high precision and rigidity. Cylindrical rollers are arranged perpendicularly in 90° V‑grooves via a precision spacer retainer, enabling the bearing to support radial, axial, and moment loads simultaneously in a compact profile.

Key Design Features
- Two‑Piece Inner Ring: Split inner‑ring design enables outer‑ring rotation with high precision, ideal for applications requiring stable outer‑ring motion.
- Ultra‑Thin & High Rigidity: Crossed roller arrangement delivers 3–4× higher rigidity than conventional double‑row thin angular contact bearings in a compact profile.
- Multi‑Directional Load Capacity: Single bearing supports radial, axial, and moment loads, simplifying mechanical design and reducing component count.
- Stable Low Torque: Spacer retainers prevent roller skewing and eliminate roller‑to‑roller friction, ensuring consistent, smooth rotation.
- Contamination Protection: UU double seals block dust, chips, and coolant ingress, extending service life in industrial environments.
- Easy Installation: Pre‑assembled with rollers and retainer for direct installation; split inner ring simplifies mounting and preload adjustment.
- Standard Clearance (C0): Factory‑set radial clearance ensures smooth operation and consistent performance under varying loads.
Typical Applications (THK Recommended)
- Precision rotary tables for machine tools and measuring instruments (outer‑ring rotation)
- 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
- Compact rotary actuators and lightweight robotic swiveling units
- High‑precision indexing tables and rotary actuators
