Key Official Features
- Anti‑Creep Mechanism: Rack‑and‑pinion integrated design prevents cage displacement; no cage creep correction required for vertical axis, high‑speed or continuous operation.
- Interchangeability: Identical outer dimensions to standard CRW3 series, direct replacement in existing designs.
- Multi‑Directional Load Capacity: Crossed roller arrangement withstands radial, lateral and moment loads in all directions.
- High Rigidity & Precision: Minimal elastic deformation, ideal for precision positioning, micro‑feeding and high‑accuracy linear motion equipment.
- Smooth Motion: Low friction, no stick‑slip, delivering superior positioning accuracy.
