Competitive price steel cage needle roller bearing HK series

Feature:

1. Drawn cup needle roller bearing with a closed end for shaft end applications with high dynamic loads

2. Drawn steel outer shell (cup) has a reduced cross-section for use in restricted spaces

3. Steel cage guides and evenly spaces rollers for reduced friction, vibration, and noise

4. Through-hardened, high-carbon chromium steel rollers for heat tolerance and durability under heavy loads 

HK series needle roller bearing has a closed end and is suitable for shaft end applications with high dynamic loads. It has a smaller cross-section than a machined needle roller bearing for use in restricted mounting spaces. The steel cage provides guidance and even spacing of the rollers for minimum vibration and noise when operated at high speeds. The needle rollers are made of through-hardened, high-carbon chromium steel for durability and heat tolerance.

Roller bearings use rolling elements to maintain a separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Roller bearings can be open on both ends (a shaft can pass through) or open on one end and closed on the other. An open end can be sealed or shielded to protect the bearing from solid contaminants and moisture that could reduce its lifespan. If an end is sealed, the sealing component is an elastomer lip that contacts the shaft. If it is shielded, the shielding is a non-contact lip, usually made of metal. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers etc.
