HKB20 Marginal lubricating Bearing

It is a sliding bearing made of high-quality cold-rolled steel plate as the substrate, sintered with porous spherical bronze powder in the middle, and then rolled and bonded with a layer of modified polyoxymethylene on the surface of the porous spherical bronze powder layer, which is then rolled and produced. This type of bearing, due to its surface rolling with oil storage pits with spiral angles arranged in a regular pattern, needs to be coated with lubricating grease during assembly. It is particularly suitable for situations where fluid lubrication is difficult to form under high load and low speed. The oil storage pits on its surface can ensure optimal grease distribution and can be maintained without refueling for a long time.
