Accurate Bushing CR-1-1/4-X Plain Stud Cam Follower

Product Description

The ACCURATE BUSHING CR-1-1/4-X is a plain stud cam follower designed for use in industrial motion control and power transmission applications. Built with a steel needle roller bearing and a sealed closure, it delivers reliable radial load performance in demanding track and cam applications. The roller measures 1-1/4 inches in diameter and 0.75 inches in width, with a 0.5 inch stud diameter and a 1-1/4 inch stud length. Dynamic load capacity is rated at 4,470 pounds and static load capacity at 4,300 pounds, making it suitable for moderate-to-heavy cyclic loading conditions. The 1/2-20 threaded stud with a 5/8 inch thread length allows secure mounting into standard tapped bores or bracket fixtures.

This cam follower is used in conveyor systems, indexing mechanisms, die sets, and general machinery where a roller must track a cam surface or linear guide. The sealed design helps retain lubrication and exclude contaminants in light-duty washdown or dusty environments. The slotted head type allows for torque application with standard hand tools. It is typically installed by industrial maintenance technicians or mechanical assemblers working on factory automation, material handling, and machine tool equipment.

Key Features

• Needle roller bearing design for high radial load capacity in a compact envelope
• Sealed closure retains grease and resists contaminant ingress
• 4,470 lb dynamic load capacity and 4,300 lb static load capacity
• Non-crowned roller profile for full-face contact on flat cam tracks
• Slotted head stud for easy installation and removal with common hand tools
• All-steel construction for durability in industrial service

Compatibility

Designed as an OEM-style replacement or direct-fit stud cam follower for industrial machinery requiring a 1-1/4 inch roller diameter, 1/2-20 threaded stud, needle roller bearing configuration.

Installation Notes

Installation is performed by qualified maintenance technicians or mechanical assemblers. De-energize and lock out all power to the machine before removing or installing cam followers. Thread the stud into the tapped mounting hole using a wrench on the slotted head and verify secure engagement before returning the assembly to service. Do not exceed the rated dynamic or static load capacities for the application.
