HMK Needle roller bearings are a special type of roller bearing characterized by slender needle rollers. Different from other rolling bearings, needle roller bearings feature ultra-small radial section, compact structure and outstanding radial load capacity, which are the optimal solution for equipment with limited installation space.

We supply a full range of needle roller bearings, including solid ring needle bearings with or without inner ring and drawn cup shell-type needle bearings. Complete series cover NA, NKI, NK, HK and other mainstream specifications to meet various industrial working conditions.

Core Advantages

1. Ultra-compact Size

Small radial dimension saves installation space, ideal for narrow and compact mechanical structures where other bearings cannot be installed.

2. Excellent Radial Load Capacity

Equipped with a large number of needle rollers, these bearings can bear heavy radial loads and maintain stable operation under continuous working conditions.

3. Diversified Structural Types

Available in solid ring type and drawn cup type; optional inner ring design to adapt to different assembly requirements and installation environments.

4. Low Friction & Long Lifespan

Adopts high-quality bearing steel and precision grinding technology, effectively reducing running friction, wear resistance and extending service life.
