Accurate Bushing CR-3-1/4-B Stud Cam Follower with Hex

Product Description

The ACCURATE BUSHING CR-3-1/4-B is a stud cam follower with hex drive, manufactured from carbon steel for use in industrial motion control and conveyor applications. The roller measures 3.25 inches in diameter and 1.75 inches in width, riding on a 1.25-inch-diameter stud that is 2.5 inches long with a 1.25-inch thread length and 1.25-12 thread specification. The overall assembly length is 4.25 inches. With a dynamic load capacity of 20,200 pounds, this follower is built for demanding cyclic-load environments where reliable rolling contact is required. Licensed tradesmen and industrial maintenance technicians typically specify and install this component.

Stud cam followers in this size range are used in heavy-duty industrial machinery, including conveyor systems, indexing tables, die sets, and linear guide assemblies. The hex-drive feature on the stud allows for precise positioning and secure tightening during installation. This particular follower is suited for applications requiring high radial load capacity under continuous or intermittent motion, particularly in manufacturing and process equipment where replacement cycles demand an OEM-compatible fit and consistent load ratings.

Key Features

• 3.25-inch roller diameter provides a large contact surface for distributing radial loads
• 20,200 lb dynamic load capacity rated for heavy cyclic-load applications
• Carbon steel construction for durability in industrial environments
• 1.25-12 threaded stud with hex drive for controlled torque installation
• 1.75-inch roller width supports stable tracking on cam surfaces and rails
• 4.25-inch overall length accommodates standard mounting depths in industrial assemblies

Compatibility

Designed as an OEM-style replacement stud cam follower for heavy-duty industrial motion control and conveyor machinery requiring a 3.25-inch roller diameter, 1.25-inch stud diameter, and 1.25-12 thread specification.

Installation Notes

Installation is typically performed by licensed industrial maintenance technicians or mechanical assemblers. Before servicing, de-energize all associated machinery and relieve any spring or pneumatic tension in the system. The hex-drive stud should be threaded into the mounting structure and tightened using standard wrenching tools appropriate to the application. Do not exceed the rated dynamic load capacity of 20,200 pounds, and verify thread engagement depth meets the equipment manufacturer's specifications before returning the system to service.
