Accurate Bushing CR-3/4-XB Plain Cam Follower Sealed Stud

Product Description

The ACCURATE BUSHING CR-3/4-XB is a sealed stud-type cam follower with a needle roller bearing, designed for use in mechanical motion-control and power-transmission applications. It features a 0.75 inch roller diameter, a 0.5 inch roller width, and a 0.375 inch stud diameter with a 0.875 inch stud length. The roller is manufactured from steel and runs on a needle roller bearing, providing high load capacity in a compact envelope. Dynamic load capacity is 2,140 pounds and static load capacity is 2,200 pounds. The sealed closure keeps contaminants out of the bearing, reducing maintenance requirements in industrial service environments. Maintenance technicians and mechanical assemblers are the typical installers of this component.

This cam follower is suited for use in cam-and-follower mechanisms, conveyor systems, automation equipment, and other industrial machinery where a stud-mounted roller tracking element is required. The 3/8-24 threaded stud with a 0.375 inch thread length and 3/16 inch hex size allows for installation into threaded bores on cam tracks, guide rails, and follower arms. The non-crowned roller profile maintains consistent contact across the full roller face, making it appropriate for flat track surfaces in linear and rotary motion assemblies.

Key Features

• 0.75 inch steel roller with non-crowned profile for flat-track contact
• Needle roller bearing type for high radial load capacity in a compact form
• Sealed closure protects bearing from contamination and reduces lubrication intervals
• 2,140 lb dynamic load capacity and 2,200 lb static load capacity
• 3/8-24 threaded stud with 3/16 inch hex for standard installation tooling
• Carbon steel construction for durability in industrial service conditions

Compatibility

Designed as an OEM-style replacement or direct-fit component for cam-and-follower assemblies requiring a 0.75 inch roller diameter, 3/8-24 stud thread, sealed needle roller construction.

Installation Notes

Installation is typically performed by mechanical technicians or industrial maintenance personnel. De-energize and lock out all equipment before removing or installing cam followers. Thread the stud into the follower arm or mounting plate using a 3/16 inch hex key, applying torque per the assembly drawing specifications for the host equipment. Verify roller alignment with the cam track surface before returning the mechanism to service.
