SF-1 type bearing and SF-2 type bearing 2 kinds of bearings, which is used in heavy and low speed, which is used in high speed and low load? Is it the mixture of rolled surfaces
Lubrication material is divided into several kinds, strictly speaking, RAMSHIN production of SF-2 bearing with POM is not solid lubrication material, is a good mechanical properties of composite material, work also need to oil lubrication, so called boundary lubrication bearing, generally used in heavy and low speed occasions, such as: metallurgy, construction machinery, hydraulic engineering
