According to the different bearing series and sizes, there are two different designs. The seal ring is made of stamping steel, usually with a cylindrical extension at the inner diameter of the sealing ring, forming a long sealing gap with the inner ring shoulder. Some seals do not extend.
Bearing with low friction seal ring: the suffix is RSL, 2RSL or RZ, 2RZ, according to different bearing series and size, it also has different structural design.A very narrow gap to form a cylindrical surface or the inner concave contour of the sealing ring and the inner ring shoulder, is actually not contact, therefore, a low friction bearing seal and bearing with Z can run the dustproof cover at the same speed, but its better sealing performance.
Bearing with contact seal ring, the suffix is RSH, 2RSH or RS1, 2RS1 Sealed Angular Contact Bearings Sealed Angular Contact Bearings,Lip Sealed Angular Contact Bearings,Durable Sealed Angular Contact Bearings,Ball Bearing For Machine Tool Spindles LUOYANG AUTO BEARING CO.,LTD , http://www.lyautobearing.com
