Product Overview

Description

NK30/30 Needle Roller Bearings NK Series Without Inner Ring 30x40x30 m 

 

C&H Roller bearings are with cylindrical needle rollers, needle roller bearings have a compact structure, because the ratio of the inner diameter and the outer diameter of the bearing is small, so it has a relatively large radial load capacity. Therefore, it is very suitable for occasions where radial space is limited. This type of bearing is suitable for occcsions where shaft and seat hole can be used as rolling raceway . Main applications are Automotive, machine tools, textile and other types of machinery. Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between the axle and the surrounding structure.
