NTN Needle Bearing HKS 20x29x18

The NTN HKS 20×29×18 is a drawn-cup needle roller bearing designed for applications requiring a compact yet durable bearing. It has an inner diameter of 20 mm, an outer diameter of 29 mm, and a width of 18 mm.

Using long, narrow needle rollers instead of balls, it can handle high radial loads while maintaining a minimal cross-section height, making it ideal for tight spaces such as shafts, gearboxes, small engines, and other rotating mechanisms. The drawn-cup design features a thin, hardened steel outer sleeve, with the shaft itself acting as the raceway. Properly installed and lubricated, this bearing ensures smooth rotation and long service life in compact applications.
