Accurate Bushing CR-1-3/8-B Plain Cam Follower Stud Type

Product Description

The ACCURATE BUSHING CR-1-3/8-B is a stud-type plain cam follower designed for use in linear and rotary motion applications where a rolling element must track a cam surface or guide rail. Built around a needle roller bearing, it delivers a dynamic load capacity of 4,470 pounds in a compact envelope. The roller measures 1.375 inches in diameter and 0.75 inches wide, with a 0.5-inch stud diameter and a 1/2-20 threaded stud. The steel roller and carbon steel construction make this follower well suited for demanding industrial, conveyor, and machine-tool environments. Maintenance technicians and millwrights are the typical installers.

This cam follower is used in applications requiring guided tracking along cam profiles, track rails, or flat surfaces in industrial machinery, automation equipment, and conveyor systems. The unsealed construction is appropriate for dry or lightly lubricated environments where the installer manages lubrication intervals. The hex head on the stud allows precise torque application during installation. The 1.25-inch stud length and 0.625-inch thread length provide adequate engagement for standard mounting plate thicknesses common in machine frames and weldments.

Key Features

• Needle roller bearing provides high radial load capacity relative to envelope size
• Dynamic load capacity of 4,470 pounds for demanding duty cycles
• 1/2-20 threaded stud with 1/4-inch hex head for controlled installation torque
• Non-crowned roller profile for consistent contact across full roller width
• Unsealed design suits applications with controlled lubrication access
• Carbon steel construction for strength in industrial service conditions

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial machinery, automation systems, and conveyor assemblies requiring a stud-type cam follower with a 1.375-inch roller diameter and 1/2-20 stud thread.

Installation Notes

Installation is typically performed by millwrights or industrial maintenance technicians. De-energize all connected machinery and lock out or tag out power sources before beginning installation per applicable OSHA lockout/tagout procedures. Use the 1/4-inch hex drive on the stud to seat and tighten the follower into the mounting bore without applying force to the roller itself. Inspect the mating cam surface or track rail for wear or damage before fitting the new follower, as surface irregularities will accelerate bearing wear.
