Model: Needle Roller Bearing

Material: Bearing Steel

Applications : The outer ring of needle roller bearing is formed by precision stamping of thin steel plate, the structural space is small, and has a large load capacity, They are suitable for applications where the installation space is restricted and the housing bore can be used as a raceway 

Features:

Core Structure and Functional Features

Bidirectional Axial Positioning

This is its most fundamental characteristic. The bearing features fixed flanges at both ends, simultaneously restricting axial movement in two directions (i.e., bidirectionally).

Function: It can withstand axial forces from one direction as well as opposing axial forces from the opposite direction, thereby precisely securing the shaft at a predetermined axial position.

Compact and Lightweight Design

Utilizing needle rollers as rolling elements, which feature small diameters and long lengths, HK bearings achieve higher load capacities than ball bearings or other types within the same radial space. Simultaneously, their extremely low cross-sectional height enables an exceptionally “thin-walled” design.

Advantages: Particularly suitable for space-constrained, weight-sensitive micro-precision devices.

High Radial Load Capacity

The line contact between the needles and raceways provides a significantly larger contact area compared to the point contact of ball bearings. Consequently, HK bearings exhibit exceptional radial load-bearing capability within the miniature bearing category.

High Rigidity

Another benefit of line contact is superior rigidity. Under load, the bearing exhibits minimal deformation, ensuring transmission accuracy and stability—critical for precision instruments and high-speed components.
