FAG Needle Roller Bearings Guide

Product Description

The PNA20/42-XL INA aligning needle roller bearing consists of a drawn outer sleeve, a plastic support ring with a concave inner surface, an outer ring with a spherical outside surface, a needle roller and cage assembly, and a removable inner ring. The inner ring provides a precision raceway for the needle rollers. Its aligning design can compensate for static misalignment between the shaft and housing, while the needle roller arrangement provides high radial load capacity within a compact radial cross-section. In addition, X-life increases load carrying capacity and extends operating life.

The PNA20/42-XL bearing is suitable for industrial transmissions, agricultural machinery, textile machinery, printing and packaging, material handling, and general mechanical engineering. Its aligning capability helps compensate for shaft-to-housing misalignment, while the inner ring allows use where the shaft cannot serve directly as a raceway. Meanwhile, the combination of high radial load capacity, compact dimensions, misalignment compensation, and long service life supports reliable operation in mechanical systems with alignment variations.
