Needle Roller Bearings

The rolling elements in the needle bearing are thin and long cylinders. Their small dimensions make them suitable for special requirements. Depending on the variant, an inner ring is omitted, the needle roller then rolls directly on the shaft or axle. Most radial needle bearings have very good floating properties.
