FAG Needle Roller Bearings Guide

Product Description

The NAO25×42×32-ZW-ASR1-XL FAG machined needle roller bearing consists of a ribless machined outer ring, an inner ring, two rows of needle rollers, and cage assemblies. The ZW double-row design provides high radial load capacity and rigidity within a compact radial cross-section. Since the bearing has no ribs, the needle roller and cage assembly can be mounted together with either ring or inserted between the inner and outer rings. In addition, X-life improves load carrying capacity and extends operating life.

The NAO25×42×32-ZW-ASR1-XL features an ASR1 lubrication hole and lubrication groove, which facilitate lubricant supply to the rolling elements. The bearing is suitable for industrial transmissions, machine tools, printing and packaging, textile machinery, material handling, and general mechanical engineering. Its combination of double-row radial load capacity, high rigidity, compact dimensions, and effective relubrication supports reliable operation in highly loaded mechanical systems.
