FKI Logistex 501239 Idler Roller 3-1/2 Diameter 1-1/8 Axle

FKI Logistex 501239 Idler Roller is an industrial component from the FKI Logistex family, identified by part number 501239. It features a 3-1/2" diameter and a 1-1/8" axle, delivering the exact dimensions needed for installations that require this roller size. As an idler roller, it serves as a non-drive element that supports and guides moving belts or other line materials, allowing smooth rotation under load. The compact dimensions — 3-1/2" diameter with a 1-1/8" axle — make it suitable for configurations where space is constrained and precise fitment is essential. Referencing the manufacturer and part number helps ensure correct replacement or stocking for compatible systems, reducing the risk of mismatches during maintenance. With this specific specification set, technicians can verify compatibility based on the 501239 designation, the 3-1/2" diameter, and the 1-1/8" axle to support reliable uptime in industrial material-handling environments.
