Needle Bearing

Needle roller bearings are roller bearings with cylindrical rollers, but the rollers of the needle bearing are thin and long relative to their diameter. These rollers are called needle rollers. The bearing still has a high load-carrying capacity despite its small cross-section. Because the needle roller bearing is equipped with a thin and long roller, it’s radial structure is compact. When its inner diameter size and load capacity are the same as other types of bearings, the outer diameter of the needle bearing is the smallest, so the scope of application of this bearing Very wide.

Structural features of Needle bearing

Needle roller bearings are a special type of roller bearings, generally divided into two categories: stamped outer ring type and solid ring type. It uses long, thin cylindrical rollers like needles. A roller of a conventional roller bearing is only slightly longer than its diameter, but a needle bearing usually has a roller that is at least four times longer than its diameter. Like all bearings, they are used to reduce friction on rotating surfaces. Compared to ball bearings and plain roller bearings, needle bearings have a larger surface area in contact with the raceway, so they can withstand higher loads. Needle bearings manufactured by SWS Bearings LTD are: NA… series, HK… series, K… series.
