Exploration of the lubrication mode of high-speed bearing

Bearings with dust cover Bearings with dust cover, suffix 2z, dust cover is made of stainless steel. Dust cover Jade inner ring shoulder to form a very narrow gap, and can withstand high temperatures and high speed. Bearings with dust cover is mainly used in the inner ring rotating conditions. If the outer ring is turned, the bearings running at high speed will cause the grease to leak. Bearings with seals Bearings with contact seals, suffix 2rs1, seals are made of steel with anti-oil and anti-wear nitrile rubber. This thank the ring is allowed to work temperature is -40 to +100 ℃, in a short time up to + 120 ℃. The contact lip seals the shoulder of the inner ring. The outer edge of the seal ring groove in the outer ring, in this position can provide a good seal. When sealed bearings operate under extreme conditions, such as extreme speeds or temperatures, grease may leak between the inner ring and the seal. If leaks can cause damaging effects on the bearing configuration, special design steps are required.
