Mcgill 4080100000 Yoke Cam Follower Needle Roller

Product Description

The MCGILL 4080100000 is a yoke-type cam follower with a crowned steel roller and needle roller bearing internals, designed for use in cam-and-follower mechanisms found in industrial machinery, conveyor systems, and motion-control assemblies. The roller measures 7/8 inches in diameter with a 0.5 inch width and accepts a 0.25 inch bore. Dynamic load capacity is rated at 1,660 pounds, and the needle roller bearing design allows for smooth, low-friction tracking under radial loads. The crowned roller profile helps accommodate minor misalignment and reduces edge stress during operation. Installation is performed by qualified maintenance technicians and mechanical tradespeople.

This cam follower is suited for applications where a yoke-style stud mount is required and the follower must track a cam surface under moderate to heavy radial loading. The crowned roller geometry makes it a practical choice in applications where shaft or cam surface parallelism cannot be perfectly maintained. With a maximum speed rating of 5,400 RPM and a static load capacity of 4,130 pounds, it covers a wide range of light industrial and precision machine tool applications. The unsealed bearing configuration is appropriate for environments where the technician manages lubrication as part of a scheduled maintenance routine.

Key Features

• Crowned roller profile reduces edge loading and tolerates minor misalignment
• Needle roller bearing design delivers high radial load capacity in a compact envelope
• Dynamic load capacity of 1,660 pounds and static load capacity of 4,130 pounds
• Maximum operating speed of 5,400 RPM
• Unsealed construction allows field lubrication and maintenance access
• Steel roller and steel construction for durability in industrial service

Compatibility

Designed as a yoke-style cam follower replacement; McGill part number CYR 7/8 cross-reference applies. Verify bore diameter, roller diameter, roller width, and overall width against the application before installation.

Installation Notes

Yoke cam followers are installed by qualified mechanical technicians. De-energize and lock out all power sources before servicing the machine assembly. Ensure the mounting bore and mating shaft are clean and within tolerance before pressing or bolting the follower into position. Because this follower is unsealed, apply the appropriate lubricant per the equipment manufacturer's maintenance schedule after installation.
