Overview
The McGill CFH 7/8 B cam follower is a precision stud-type bearing engineered for demanding industrial machinery applications. This McGill CF Camrol series steel heavy-duty stud-type cam follower bearing with lip seals and a hexagonal hole supports high static and dynamic loads in cam- and track-type applications. The CFH designation indicates heavy stud construction, which provides greater load-carrying capacity than standard studs.
Key Features
- Needle rolling elements with flat roller shape for efficient load distribution
- Heavy stud configuration with hex hole design for secure mounting and higher static loads
- Thick-walled outer ring that helps minimize deformation under heavy radial and shock loads, with zone-hardened working surfaces to support contact stresses
- Moly-filled nylon lip seals (Lubri-Disc) on both sides retain lithium base grease and help protect against contaminants
- Manufactured from bearing quality steel with black oxide finish and factory filled with grease
- Lubrication holes on both ends of the stud and cross-drilled hole in the stud shank for relubrication and venting of excess grease
