Accurate Bushing CR-1-1/2 Plain Stud Cam Follower

Product Description

The ACCURATE BUSHING CR-1-1/2 is a plain stud cam follower designed for use in linear and rotary motion applications where a rolling element must track a cam or guide surface under significant load. Built with a steel needle roller bearing and a steel outer roller, this follower delivers a dynamic load capacity of 5,560 pounds and a static load capacity of 5,730 pounds. The 0.625-inch stud diameter is threaded 5/8-18 UNF with a 0.75-inch thread length, providing secure mounting to machine frames, conveyor systems, and linkage assemblies. Licensed millwrights, maintenance mechanics, and industrial technicians are the typical installers.

This cam follower is suited for both light industrial and heavy-duty machinery applications where a 1.5-inch roller diameter is specified. The non-crowned roller profile maintains consistent contact across the full roller width on flat cam and track surfaces. The unsealed design is appropriate for controlled environments where the installer manages lubrication intervals. Typical applications include conveyor guides, indexing mechanisms, and cam-driven linkage systems requiring a studded follower in the 1.5-inch roller class.

Key Features

• 1.5-inch roller diameter with non-crowned, flat roller profile for uniform surface contact
• Needle roller bearing construction supports 5,560 pounds dynamic load capacity
• Static load capacity of 5,730 pounds for applications with sustained clamping or dwell loads
• 5/8-18 UNF threaded stud with 0.75-inch thread length for secure, precise mounting
• Steel roller material provides durability in demanding cam and track environments
• Unsealed closure allows for serviceable lubrication in controlled installation settings

Compatibility

Designed as a standard stud-type cam follower for machinery and conveyor applications specifying a 1.5-inch roller diameter, 5/8-18 UNF stud thread, and needle roller bearing construction.

Installation Notes

Installation is typically performed by licensed millwrights or qualified maintenance mechanics. De-energize and lock out all power sources to the machine before removing or installing cam followers per OSHA lockout/tagout requirements. Verify thread engagement depth and apply thread-locking compound as appropriate to the application. The unsealed bearing requires periodic lubrication; follow the equipment manufacturer's lubrication schedule for needle roller follower components.
