Mcgill 4140110000 Crowned Cam Yoke Roller Needle Bearing

Product Description

The MCGILL 4140110000 is a sealed yoke-type cam follower with a crowned roller profile and needle roller bearing internals. It is designed for use in cam-and-follower mechanisms where the roller must track a cam surface or linear rail under radial load. The crowned roller profile allows for slight misalignment without edge loading, reducing stress concentrations on the raceway. Key ratings include a dynamic load capacity of 4,840 pounds and a static load capacity of 11,280 pounds, making it suitable for moderate-to-heavy duty industrial applications. The sealed construction retains lubrication and excludes contaminants. Millwrights, maintenance mechanics, and industrial service technicians typically install and replace this component.

This cam yoke roller is used in industrial machinery where a yoke-end stud mount is required for attaching the follower to a linkage, slide, or actuator assembly. Typical applications include cam-actuated mechanisms, conveyor systems, indexing equipment, and material handling machinery. The crowned roller shape accommodates minor shaft or track misalignment encountered in real-world installations. It is rated to a maximum speed of 2,500 RPM, making it appropriate for both low-speed, high-load and moderate-speed cycling applications in manufacturing and processing environments.

Key Features

• Crowned roller profile reduces edge stress and tolerates slight angular misalignment
• Needle roller bearing type provides high radial load capacity in a compact cross-section
• Sealed closure type retains grease and protects against contamination
• Dynamic load capacity of 4,840 pounds and static load capacity of 11,280 pounds
• Maximum operating speed of 2,500 RPM
• Steel roller and steel construction for durability in industrial service

Compatibility

Designed as an OEM-style replacement yoke cam follower for industrial machinery requiring a sealed, crowned needle roller cam follower with a 0.4375-inch bore and 1-1/2-inch roller diameter. McGill part number CYR 1-1/2 S is the manufacturer cross-reference for this component.

Installation Notes

Installation and replacement of cam yoke rollers should be performed by qualified millwrights or maintenance technicians. De-energize and lock out all power sources and relieve any stored mechanical energy before removing the existing follower. Ensure the mating cam surface or track is inspected for wear before installing the new roller. Do not press or strike the roller directly during installation; use appropriate bearing installation tooling to avoid damage to the needle roller assembly.
