Overview
The McGill CFH 3/4 S is a heavy stud cam follower bearing engineered for demanding industrial automation and mechanical motion control systems. This unit features full-complement needle roller construction, which provides superior radial load capacity and shock resistance compared to caged needle bearing designs. The sealed LUBRI-DISC® enclosure extends bearing life by protecting against contaminant entry while retaining lubrication. McGill CAMROL® bearings are manufactured with black oxide-treated bearing steel and induction heat-treated studs for reliable long-term performance in production environments.
Key Features
- Full-complement needle roller construction — delivers high radial load capacity and improved shock loading resistance
- Heavy stud profile — reinforced outer race design for robust cam follower operation under load
- Sealed enclosure with LUBRI-DISC® seals — protects bearing internals while venting excess or old grease
- Induction heat-treated stud — enhanced surface durability in the roller path and flange areas
- Flat roller surface profile — precision engineered for reliable contact and motion control
- Hex head mounting — standard socket interface for secure installation

Compatibility & Replacements
Compatible With
- McGill CAMROL® mounting systems and housings
- Standard industrial cam-driven machinery with hex socket mounting
- Mechanical automation equipment requiring sealed needle roller bearings
- Heavy stud cam follower mounting interfaces
- Equipment operating in low to moderate relubrication environments
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering for specific OEM or legacy equipment replacement scenarios. The CFH 3/4 S is a standard McGill CAMROL® series bearing and maintains dimensional and load-rating compatibility with other CFH 3/4 models (such as CFH 3/4 SB, CFH 3/4 B variants) when stud and mounting configurations match.
Works With
- McGill CAMROL® bearing systems and maintenance programs
- Standard industrial automation machinery compatible with sealed needle roller cam followers
- Mechanical power transmission and linear motion control systems
- Equipment designed for sealed (non-relubricatable) bearing operation
