Mcgill 4240110000 Crowned Cam Yoke Roller 2.5 in Bore 0.75 in

Product Description

The MCGILL 4240110000 is a sealed yoke cam follower designed for industrial motion control and power transmission applications. It features a crowned steel roller measuring 2.5 inches in diameter with a 1.5 inch roller width and a 0.75 inch bore. The internal needle roller bearing design delivers high radial load capacity in a compact envelope, supporting a dynamic load rating of 11,720 pounds and a static load capacity of 32,900 pounds. The sealed closure type protects the bearing from contamination in demanding environments. Rated to a maximum of 1,100 RPM, this cam follower suits moderate- to high-load applications where reliable rolling contact is required. Installation is typically performed by millwrights, maintenance technicians, or mechanical assemblers.

This yoke cam follower is suited for use in industrial machinery, conveyor systems, cam-driven mechanisms, and linear guidance applications where a crowned roller profile is needed to accommodate slight shaft misalignment or edge loading. The crowned roller geometry distributes contact stress across the roller face, reducing edge stress concentrations during operation. The sealed design makes it appropriate for environments where periodic relubrication access is limited. Typical installations occur in manufacturing, material handling, and automated assembly equipment.

• Sealed closure type protects against contamination without requiring external seals
• Dynamic load capacity of 11,720 pounds and static load capacity of 32,900 pounds
• Maximum operating speed of 1,100 RPM
• Steel roller and steel body construction for durability in industrial environments

Compatibility

Also referenced by McGill part number CYR 2-1/2 S. Designed as an OEM-style replacement or direct-fit yoke cam follower for industrial machinery using a 0.75 inch bore crowned needle roller cam follower of this envelope size.

Installation Notes

Installation is performed by qualified mechanical technicians or millwrights. De-energize and lock out all power sources before servicing any machinery containing this component. Ensure the mounting stud or shaft is clean, dimensionally correct, and free of burrs before pressing or threading the cam follower into position. Do not apply impact loads directly to the roller or outer race during installation.
