Short Description:

Needle roller bearing is a special type of roller bearing that has cylindrical rollers that resemble needles because of their small diameter.

Needle bearing is a roller bearing with cylindrical rollers. The rollers are thin and long relative to their diameters. This kind of roller is called needle roller. The bearing has a high load carrying capacity despite its small section.

Product Detail

Product Tags

Normally, the length of rollers in roller bearings is only slightly more than its diameter. When it comes to needle bearing, the length of rollers exceeds their diameter by at least four times.

As needle bearings have a smaller diameter, more rollers can be fit in the same space which increases the surface area in contact with the races. Thus, they are capable of handling high loads. The small size can also prove helpful in applications where space is limited as they require smaller clearances between the axle and the housing. To ensure that the load capacity and operating performance are the same as those of the bearing with ring, the hardness, machining accuracy and surface quality of the surface of the shaft or shell hole raceway shall be similar to that of the raceway of the bearing ring. This type of bearing can only bear radial load.
