Mcgill 2120112000 Plain Cam Follower Sealed Stud Hex

Product Description

The MCGILL 2120112000 is a sealed stud-type cam follower with a hex head, designed for use in mechanical power transmission systems where a rolling contact element must track a cam or guide surface. The roller measures 1.25 inches in diameter and 0.75 inches wide, supported by a needle roller bearing assembly inside a steel roller. The stud is 0.5 inches in diameter and 1.25 inches long, threaded 1/2-20 with a 0.625-inch thread length. Dynamic load capacity is rated at 3,930 pounds, making this follower suitable for moderate-to-heavy radial loading in industrial machinery, conveyor systems, and automation equipment. Licensed trades and mechanical technicians are the typical installers.

This cam follower is used in applications where a track roller or stud-mounted follower is required to ride against a cam surface, guide rail, or track. Typical installations include linear motion systems, indexing machinery, packaging equipment, and material handling assemblies. The sealed closure type retains internal lubrication and excludes contaminants, extending service life in dirty or high-cycle environments. The hex head stud design allows for straightforward torque application during installation without requiring special tooling beyond standard hex wrenches.

Key Features

Compatibility

Designed as an OEM-style replacement stud cam follower for industrial machinery requiring a 1.25-inch diameter cylindrical roller with a 0.5-inch stud diameter and 1/2-20 thread. McGill equivalent part number CF 1-1/4 SB is referenced in the manufacturer specifications.

Installation Notes

Installation is performed by mechanical technicians or millwrights. De-energize and lock out all power to the machine before replacing any cam follower. Use a calibrated torque wrench with the appropriate hex socket to thread the stud into the mounting bore — do not over-tighten or cross-thread. Verify roller alignment with the cam or track surface before returning the machine to service.
