Accurate Bushing CR-3/4 Plain Stud Cam Follower 0.75in

Product Description

The ACCURATE BUSHING CR-3/4 is a stud-type plain cam follower designed for use in cam-and-follower mechanisms, linear motion systems, and machine guideways. This needle roller bearing follower features a 0.75-inch roller diameter and a 0.5-inch roller width, making it suited for applications with moderate radial loads in confined track assemblies. The steel roller and stud construction deliver a dynamic load capacity of 2,140 pounds and a static load capacity of 2,260 pounds. The 3/8-24 threaded stud with a 3/8-inch thread length allows direct mounting into a tapped bore. Installed by millwrights, maintenance mechanics, and machine builders in production and industrial settings.

The CR-3/4 is intended for industrial machinery applications including conveyor systems, packaging equipment, indexing mechanisms, and automated assembly lines. The non-crowned roller profile makes it best suited for flat track surfaces where even load distribution across the roller face is required. The unsealed design is appropriate for clean or controlled environments where the installer manages lubrication during assembly and service intervals. The slotted head type aids installation and removal with standard tooling.

Compatibility

Designed as an OEM-style replacement or direct-fit stud cam follower for industrial machinery that accepts a 3/8-24 stud cam follower with a 0.75-inch roller diameter and needle roller bearing construction.

Installation Notes

Installation is performed by qualified millwrights or maintenance mechanics following applicable machinery safety lockout/tagout procedures before servicing any cam or track assembly. The threaded stud should be torqued into a properly tapped bore to ensure secure engagement without thread damage. Because this follower is unsealed, apply a compatible grease to the needle roller bearing at installation and observe the equipment manufacturer's recommended relubrication intervals. Inspect the mating track surface for wear or damage before installing a replacement follower.
