Accurate Bushing MPCR-47 Plain Stud Load Runner 47mm

Product Description

The ACCURATE BUSHING MPCR-47 is a plain stud load runner designed for industrial cam follower and track roller applications where smooth linear or curved guidance is required. The roller measures 47mm in diameter with a 27.6mm width. The stud is 20mm in diameter and 40.5mm in length, with an M20 x 1.5 thread and a 21mm thread length. Overall assembly length is 68.1mm. Constructed from carbon steel, this load runner is suited for moderate to heavy radial load conditions, rated at 12,200 N dynamic capacity and 4,900 N static capacity. Maintenance technicians and millwrights handling conveyor, cam, or linear guide systems are the typical installers.

This load runner fits into guide rail, cam track, and roller follower assemblies found in industrial machinery, automated production equipment, and conveyor systems. The plain stud configuration suits applications where the stud is mounted directly into a tapped hole or secured with a nut against a structural member. No needle or roller cage preload adjustment is required during installation, making this a straightforward replacement in existing track roller assemblies.

Compatibility

Designed as an OEM-style replacement for plain stud load runners with a 47mm roller diameter and M20 x 1.5 stud thread in industrial cam follower and track roller applications.

Installation Notes

Installation is performed by qualified millwrights or maintenance technicians. De-energize and lockout all power to the machine before servicing any roller or cam follower assembly. Thread the stud into the tapped bore or secure with a nut to the appropriate fastener specification for the machine; do not overtighten, as this can preload the roller and reduce service life. Verify roller-to-track alignment after installation to prevent uneven wear.
