FAG Needle Roller Bearings Guide

Product Description

The HK2538-ZW FAG drawn cup needle roller bearing consists of a thin-walled drawn outer cup, two rows of needle rollers, and cage assemblies, without a separate inner ring. The ZW double-row design provides increased radial load capacity within a compact radial space. Its thin-walled outer cup keeps the bearing cross-section small, while the cages guide the needle rollers and reduce friction. Therefore, the bearing combines high radial load capacity, compact dimensions, and good speed capability.

The HK2538-ZW bearing is suitable for automotive, industrial transmissions, agricultural machinery, construction machinery, material handling, machine tools, and general mechanical engineering. Its compact radial dimensions are particularly useful where installation space is limited. Meanwhile, the double-row arrangement provides higher radial load capacity, making it suitable for compact mechanical systems requiring high load density and efficient operation.
