Accurate Bushing CR-3-1/2-XBC Stud Cam Follower 3.5in

Product Description

The ACCURATE BUSHING CR-3-1/2-XBC is a crowned sealed stud cam follower with hex drive, constructed from carbon steel. It features a 3.5-inch roller diameter and a 2-inch roller width, making it suited for heavy-load tracking applications in industrial machinery. The stud measures 1.375 inches in diameter with a 2.75-inch stud length and a thread length of 1.375 inches on a 1-3/8-12 thread pitch. Overall assembly length is 4.75 inches. Dynamic load capacity is rated at 29,660 pounds and static capacity at 31,800 pounds. The sealed design retains lubrication and blocks contamination without requiring external seals during installation.

This cam follower is used in cam-and-follower mechanisms found in conveyor systems, indexing equipment, printing machinery, packaging lines, and other industrial automation applications. The crowned roller profile compensates for minor shaft misalignment and reduces edge loading under heavy or variable loads. The hex-drive stud simplifies installation and preload adjustment with standard tooling. It is typically installed by millwrights, maintenance technicians, or mechanical assemblers performing bearing replacements or new equipment builds.

Key Features

• 1-3/8-12 threaded stud with 4.75-inch overall assembly length

Compatibility

Designed as an OEM-style replacement or direct fitment for industrial cam-and-follower assemblies requiring a 3.5-inch crowned sealed stud cam follower with a 1-3/8-12 threaded stud and hex drive.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians. De-energize all power sources and relieve any mechanical tension or load from the assembly before removing the existing follower. Use a calibrated torque wrench on the hex stud to avoid over-tightening, which can preload the bearing excessively or damage the thread engagement. Verify thread engagement depth and alignment with the cam track before returning the equipment to service.
