CR3550 Spacer Ring | For B3HD Track Chains | LIS®

The CR3550 spacer ring is designed for precise axial alignment and clearance control within track chain and undercarriage systems. It absorbs axial impact and compressive loads while supporting the correct positioning of connection components within the chain assembly.

Manufactured from specially hardened steel, the spacer ring helps protect master pins, connection components and adjacent track links from premature wear. The design is intended for heavily loaded crawler and dozer undercarriage applications.
