Accurate Bushing CR-7/8-X Plain Stud Cam Follower

Product Description

The ACCURATE BUSHING CR-7/8-X is a plain stud cam follower designed for use in industrial machinery and motion control applications. This sealed needle roller bearing unit features a 7/8-inch roller diameter and a 0.5-inch roller width, with a slotted head stud measuring 0.375 inches in diameter and 0.875 inches in length. The steel roller rides on a needle roller bearing assembly, delivering a dynamic load capacity of 2,140 pounds and a static load capacity of 2,260 pounds. Maintenance and lubrication technicians working on linear or cam-actuated mechanisms install this type of component during scheduled rebuilds or unplanned repairs.

This cam follower is suited for use in conveyor systems, automated assembly equipment, packaging machinery, and other industrial drive or tracking applications that use cam-and-follower motion transfer. The sealed closure type helps protect the internal needle roller assembly from contamination in light-duty or moderate-duty industrial environments. Thread size is 3/8-24 with a 3/8-inch thread length, allowing secure installation into standard tapped bores or mounting brackets.

Key Features

• Sealed closure protects needle roller bearing from contamination and reduces maintenance intervals
• Steel roller and steel construction provide durability under repeated cyclic loading
• 2,140-pound dynamic load capacity and 2,260-pound static load capacity for reliable performance
• Slotted stud head allows installation and adjustment with standard screwdriver or spanner tools
• Non-crowned roller profile maintains consistent contact with flat cam or track surfaces
• 3/8-24 thread size for compatibility with standard tapped mounting locations

Compatibility

Designed as an OEM-style replacement stud cam follower for industrial machinery applications requiring a 7/8-inch roller diameter, 3/8-24 thread, and sealed needle roller construction.

Installation Notes

Installation is typically performed by a millwright, maintenance technician, or mechanical assembler. De-energize and lock out all power to the equipment before removing or installing cam followers. Ensure the mating cam surface or track is clean and free of damage before seating the roller. Tighten the stud to the thread engagement depth appropriate for the mounting material per the equipment manufacturer's guidelines.
