Accurate Bushing HR-3/4 Heavy Stud Cam Follower 0.75 in

Product Description

The ACCURATE BUSHING HR-3/4 is a heavy stud plain cam follower designed for use in mechanical motion control, conveyor, and linear guidance applications. Built with a carbon steel needle roller bearing assembly, this cam follower features a 0.75-inch roller diameter and a 0.5-inch roller width, providing a compact profile suited for moderate-to-heavy radial load conditions. The unsealed construction is appropriate for applications where external lubrication is applied periodically. Licensed millwrights, maintenance mechanics, and industrial equipment technicians are the primary installers of this component.

This cam follower is well suited for use in industrial machinery, automated assembly equipment, and cam-track or rail-follower systems where a heavy stud mount is required. The slotted head style allows for controlled installation torque using standard hand tools. The non-crowned roller profile maintains consistent contact along a flat cam surface or track rail. It is typically deployed in production machinery, packaging equipment, and material handling systems requiring repeatable, low-friction linear or rotary motion guidance.

Key Features

• Heavy stud cam follower design rated for 2,140 pounds dynamic load capacity
• Needle roller bearing type for efficient radial load distribution in a compact envelope
• Non-crowned, plain steel roller provides consistent flat-surface contact
• 7/16-20 threaded stud with 0.375-inch thread length and 0.875-inch stud length for secure mounting
• Slotted head type allows installation with standard slotted or spanner tooling
• Unsealed closure type suited for externally lubricated or controlled-environment applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial machinery requiring a heavy stud plain cam follower with a 0.75-inch roller diameter and 7/16-20 stud thread specification.

Installation Notes

Installation should be performed by a qualified millwright or maintenance technician. De-energize and lock out all power sources and relieve any mechanical tension before servicing cam follower assemblies. Ensure the mating cam surface or track is clean and free of debris before seating the roller. Do not exceed the rated dynamic load capacity, and verify thread engagement depth meets minimum requirements per the equipment manufacturer's specifications.
