Shielded bearings, suffix 2Z, dust cover is made ??of stainless steel. The dust cap jade inner ring shoulder to form a very narrow gap, and can withstand high temperatures and high speed. Shielded bearings used in the inner ring rotates conditions. If the outer ring rotates bearings in high-speed operation, will cause grease leakage.

With a ring of the bearing

With contact seals, bearings, suffix 2RS1, seals of nitrile rubber with steel skeleton of the anti-oil and anti-wear constant. Xie sealing ring allowable working temperature of -40 to +100 ° C up to +120 ° C, in a short time. The contact seals of the sealing lip with a shoulder of the inner ring. The gasket outer edge in a groove of the outer ring, in this location can provide a good sealing effect.

When sealed bearings run under certain extreme conditions, such as high speed or high temperature, may lead to leakage of grease between the inner ring and the seal. If the leak situation be bearing configuration is caused by the damaging impact, it certainly requires a special design steps.
