Overview
The McGill BCYR 1-3/4 S is a CAMROL unmounted cam yoke roller bearing featuring a 1-3/4 inch roller diameter and sealed LUBRI-DISC closure. This cylindrical-profile bearing uses full-complement needle roller elements with a heavy-sectioned outer race, delivering high radial load capacity and exceptional shock-load resistance for demanding cam follower applications. Built from bearing steel with black oxide finish for corrosion resistance, the BCYR 1-3/4 S suits industrial machinery, conveyor head pulleys, and linear motion systems.
Key Features
- Full-complement needle roller construction — high radial load capacity with improved shock-load resistance versus caged bearings
- LUBRI-DISC sealed closure — integral seal maintains lubrication and keeps contaminants out
- Black oxide finish — inhibits corrosion on all external surfaces
- Yoke-style mounting — enables flush installation between supports for cam tracks and rail systems
- Heavy-sectioned outer race — withstands shock loading inherent to cam follower operation
- Annular groove in outer raceway — acts as lubrication reservoir to extend service intervals
