This type of roller is called a needle roller. Although the section is small, the bearing still has a high load capacity, and the needle roller bearing is equipped with slender rollers (roller diameter D≤5mm, L/D≥2.5, L is the length of the roller), so the radial structure It is compact, with the same inner diameter size and load capacity as other types of bearings, and the smallest outer diameter, especially suitable for support structures with limited radial installation size.

the thinnest outer ring among rolling bearings, high load capacity, high maximum permissive load owing to the use of carefully selected special alloy steel plates, a surface-hardened cage with high resistance to wear, high limiting speed, and ease of mounting. automobile, electrical. (Home appliances, electric tools, fitness equipment, motors, medical devices, motorbikes, textile machines); Equipment, instrument, building machinery, rolling stock agricultural machinery and various specialized machineries.
