Accurate Bushing CR-1-1/4-XB Plain Cam Follower

Product Description

The ACCURATE BUSHING CR-1-1/4-XB is a sealed stud-type cam follower designed for use in mechanical motion-control applications where a guided rolling element must track a cam or linear surface under load. It features a 1.25-inch steel roller with a non-crowned profile and runs on a needle roller bearing assembly. The stud diameter is 0.5 inches with a 1/2-20 thread size and a stud length of 1.25 inches. Dynamic load capacity reaches 4,470 pounds and static load capacity is 4,300 pounds, making it appropriate for moderate to heavy-duty linear or rotary cam systems. A hex head configuration allows for controlled installation torque using standard tooling.

This cam follower is suited for industrial machinery, automated assembly equipment, conveyor systems, and cam-driven mechanisms in both light manufacturing and heavy production environments. The sealed closure type protects the needle roller bearing from contamination, extending service life in environments exposed to dust, chips, or coolant splash. It is typically installed by maintenance technicians or mechanical assemblers working on production equipment, jigs, fixtures, or linear guidance systems requiring a reliable stud-mounted rolling contact element.

Key Features

• 1.25-inch roller diameter with non-crowned, flat roller profile for consistent surface contact
• Needle roller bearing internals provide high radial load capacity in a compact envelope
• Sealed closure type keeps contaminants out and retains lubrication
• 4,470 lb dynamic load capacity and 4,300 lb static load capacity
• 1/2-20 threaded stud with 0.625-inch thread length and 1/4-inch hex drive for precise installation
• Carbon steel construction for durability in industrial service conditions

Compatibility

Designed as an OEM-style replacement or direct-fit cam follower for industrial machinery applications requiring a sealed stud-type needle roller cam follower with a 1.25-inch roller diameter and 1/2-20 stud thread.

Installation Notes

Installation should be performed by a qualified maintenance technician or mechanical assembler. De-energize and lock out all power sources before servicing any equipment containing this component. Use a calibrated torque wrench on the 1/4-inch hex head to achieve consistent clamping without overloading the stud thread. Verify that the mating cam surface or track is clean and free of damage before installing the follower to prevent premature wear.
