Model: IKO CRWG2‑45Series: Anti‑Creep Cage Crossed Roller Way (CRWG Series)Core Feature: Built‑in rack‑and‑pinion mechanism to eliminate cage creep, enabling stable, high‑precision linear motion even on vertical axes, high‑speed or long‑term operation.Structure: A linear motion rolling guide with cylindrical rollers alternately crossed between two V‑groove ways; supports loads in all directions with ultra‑smooth, high‑accuracy movement.Material: High‑carbon chromium bearing steel (standard); interchangeable mounting dimensions with standard CRW series.

Key Features (Official)
- Anti‑Creep Mechanism: Rack‑and‑pinion prevents cage displacement; no cage creep correction needed for vertical axis, high‑speed or continuous use.
- Interchangeability: Same outer dimensions as standard CRW series, direct replacement in existing designs.
- Multi‑Directional Load Capacity: Crossed roller arrangement withstands radial, lateral and moment loads.
- High Rigidity & Precision: Minimal elastic deformation, ideal for precision positioning equipment.
