FAQ

Question?
What does "2RS" signify in the HK3016-2RS part number?

The "2RS" suffix indicates that the bearing is equipped with contact seals made of nitrile butadiene rubber (NBR) on both sides. These seals provide excellent protection against the ingress of dirt and moisture, and they also help to retain the lubricant within the bearing, ensuring a long service life.

Yes, the HK series of drawn cup needle roller bearings is designed to run directly on a hardened and ground shaft. For optimal performance, the shaft raceway must meet specific requirements for surface hardness (typically 60 HRC), roughness, and geometric accuracy. If the shaft cannot be prepared this way, an INA inner ring (IR series) can be used.

Drawn cup needle roller bearings must be installed using a press-fit into the housing bore. It is critical to use a proper mounting mandrel that applies force only to the stamped face of the outer cup. Applying force to the open end or the rolling elements can damage the bearing. The bearing should be pressed in until its face is flush with the housing face.
