Brif introductions of needle bearing HK2020

This  caged drawn cup needle roller bearing has a steel cage and is suitable for 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 at high speeds. The needle rollers are made of through-hardened, high-carbon chromium steel for durability and heat tolerance. The bearing can be used at temperatures up to 284 degrees F (140 degrees C). This drawn cup needle roller bearing meets Deutsches Institut für Normung standard DIN 618-1 and International Organization for Standardization standard ISO 3245 for quality assurance, and is used in various applications, such as automotive and truck transmissions, agricultural and construction equipment, pumps and compressors, and two-cycle engines, among others.

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, among others.

1. Drawn cup needle roller bearings with open ends and with closed end are needle roller bearings with a very small radial section height.

2. This type bearings have by a very low sectional height and high load carrying capacity.

3. The HK Series are for the open end type and the BK Series are for the closed end type.

4. The bearings are typically used in applications where the housing bore can not be used as a raceway for a needle roller and cage assembly but where a very compact and ecnomical bearing arrangement is required.
