Planetary Gearbox Reducer Bearing

Product Description

🟢 1. Product Overview

The CPM2518 is a double-row cylindrical roller bearing without outer ring, designed specifically for planetary gearbox reducers. The outer-ring-free design allows the rollers to run directly on the gearbox housing bore, maximizing load capacity and stiffness within a compact radial space. It transmits high radial loads while permitting slight axial displacement — a standard service part for planetary reducer shafts.

Interchangeable with INA CPM2518 and equivalent gearbox reducer bearings.
