CAM Roller Linear Guide Catalog

Cam roller linear guides are linear motion systems that use linear rails and carriages equipped with cam rollers to provide smooth, controlled movement along a fixed path. The cam rollers roll along hardened raceways in the rail, creating low-friction motion while supporting higher speeds and heavier loads than many sliding systems. Because the rollers run on open raceways rather than recirculating ball tracks, cam roller guides are also more tolerant of contamination, shock loads, and minor mounting imperfections.

PBC Linear cam roller technology includes several linear guide systems engineered for different performance levels, including Redi-Rail®, Commercial Rail, V-Guide, Hardened Crown Roller, and Hevi-Rail®. These systems combine precision rails with sealed cam roller bearings to deliver reliable motion in automation, material handling, and industrial machinery. Many designs use lightweight aluminum rails with hardened steel raceways and adjustable cam rollers to maintain consistent preload, smooth travel, and long service life even in demanding environments.
