Overview
The McGill CFH 1-1/4 is a Camrol heavy stud cam follower bearing designed for industrial machinery requiring consistent, high-capacity radial load support. This stud-type cam follower features full complement needle roller construction, eliminating cage wear and maximizing load-carrying capacity. Each bearing in this box of 10 delivers robust performance in complex motion systems including packaging machinery, conveyors, and automation equipment operating under shock loading conditions.
Key Features
- Heavy stud construction for improved shock load resistance and durability
- Full complement needle roller bearings provide higher radial capacity than caged designs
- Sealed closure with relubrication capability via oil hole for extended bearing life
- Cylindrical outer race (OD) for standard cam track applications
- Induction heat-treated studs for consistent performance in high-load environments
- Black oxide finish on 52100 bearing steel for corrosion resistance
- Hex socket head for standard installation and removal
