Accurate Bushing HR-1-1/4-XB Plain Cam Follower 1.25 in

Product Description

The ACCURATE BUSHING HR-1-1/4-XB is a sealed heavy stud cam follower designed for use in industrial motion control, conveyor, and cam-driven machinery applications. It features a 1.25-inch roller diameter, a 0.75-inch roller width, and a needle roller bearing assembly that handles radial loads in high-cycle mechanical systems. The stud diameter is 0.75 inches with a 3/4-16 thread size and a thread length of 0.625 inches. Dynamic load capacity is rated at 4,060 pounds. The roller is non-crowned and constructed from steel, with a sealed closure type that retains lubrication and excludes contamination in demanding operating environments. Licensed millwrights, maintenance mechanics, and industrial technicians are the primary installers.

This cam follower is suited for residential and commercial automated equipment, production line machinery, indexing mechanisms, and cam-driven assemblies where consistent roller contact and load-bearing performance are required. The hex head configuration accepts a 0.25-inch hex key for controlled installation torque. The sealed design makes it appropriate for environments where relubrication access is limited or where contaminant ingress is a concern during operation.

Key Features

• 1.25-inch roller diameter with 0.75-inch roller width for stable contact surface
• Needle roller bearing type supports high radial dynamic load capacity of 4,060 pounds
• Sealed closure retains grease and blocks particulate contamination
• Heavy stud design with 3/4-16 thread size for secure fastening
• Non-crowned roller profile provides uniform load distribution across the roller face
• 0.25-inch hex drive on stud head for precise installation with standard tooling

Compatibility

Designed as an OEM-style replacement cam follower for industrial machinery requiring a sealed heavy stud type with a 1.25-inch roller diameter, 3/4-16 thread, and needle roller bearing construction.

Installation Notes

Installation is typically performed by qualified maintenance mechanics or millwrights. De-energize and lock out all power sources to the machine before removing or installing cam followers. Use a calibrated torque wrench with a 0.25-inch hex bit to seat the stud without overstressing the thread. Verify that the mating cam track or rail surface is free of damage before installing the new follower to avoid premature bearing wear.
