Mcgill 2120512000 Sealed Heavy Stud Cam Follower

Product Description

The MCGILL 2120512000 is a sealed heavy stud cam follower designed for use in demanding linear and rotary motion applications. It features a cylindrical steel needle roller measuring 1.25 inches in diameter and 0.75 inches wide, supported by a 0.75-inch stud diameter with a 1.25-inch stud length and 3/4-16 thread size. The sealed design protects the internal needle roller bearing from contamination and reduces maintenance intervals. This follower carries a dynamic load capacity of 3,930 pounds and a static load capacity of 8,500 pounds, making it well suited for high-load cam and track applications. Installation is typically performed by mechanical technicians and industrial maintenance professionals.

This cam follower is used in industrial machinery, conveyor systems, cam-driven mechanisms, and track-guided assemblies where a stud-mounted roller bearing is required. The hex head stud design allows for straightforward installation and adjustment using standard hex tools. The sealed closure type makes it appropriate for environments where lubrication access is limited or where contamination from debris or moisture is a concern. It is rated to a maximum of 3,100 RPM, suitable for moderate- to high-speed cam follower applications.

Key Features

Compatibility

This part is identified by McGill part number CFH 1-1/4 SB and is designed as an OEM-style replacement cam follower for industrial machinery requiring a sealed heavy stud needle roller follower in the 1.25-inch roller diameter class.

Installation Notes

Installation is performed by qualified mechanical or industrial maintenance technicians. De-energize and lockout/tagout all equipment before replacing cam followers. Use a calibrated torque wrench and appropriate hex socket to seat the stud without overloading the thread engagement. Inspect the mating cam track or rail surface for wear before installing a new follower, as a worn track will accelerate bearing degradation.
