Mcgill 4120110000 Cam Yoke Roller 1-1/4 in Crowned

Product Description

The MCGILL 4120110000 is a sealed, crowned cam yoke roller designed for use in cam follower applications where radial loads must be transferred along a track or cam surface. Built around a needle roller bearing, this follower delivers a dynamic load capacity of 3,930 pounds and a static load capacity of 8,500 pounds. The 0.375 inch bore diameter, 1.25 inch roller diameter, and 0.75 inch roller width make it a compact yet capable component for light to moderate industrial machinery. Steel construction throughout provides durability under cyclic loading conditions. Installation is typically performed by maintenance technicians and mechanical assemblers working on production equipment, conveyors, or cam-driven mechanisms.

This cam yoke roller is suited for applications in industrial machinery, automation equipment, and material handling systems where a yoke-style cam follower is required. The crowned roller profile allows for slight misalignment between the follower and the cam or track surface, reducing edge loading and extending service life. With a maximum speed rating of 3,100 RPM and a sealed closure type that retains lubrication and resists contamination, this part is appropriate for continuous-duty installations. The McGill part number cross-reference is CYR 1-1/4 S.

Compatibility

Cross-references to McGill part number CYR 1-1/4 S. Designed as an OEM-style replacement cam yoke roller for industrial machinery requiring a sealed, crowned needle roller follower with a 0.375 inch bore and 1.25 inch roller diameter.

Installation Notes

Installation should be performed by qualified maintenance technicians or mechanical assemblers. De-energize and lock out all power sources to the machine before removing or installing cam followers. Ensure the mating cam surface or track is clean and free of damage before installation. Do not press or strike the outer roller surface directly during installation, as this can damage the internal needle roller bearing.
