Driving components - Cap bearings, half bearings - Fastening with two screws

With a Shield bearing
 bearings with dust cover, the suffix for the 2Z, dust cover is made of stainless steel.  Shield formation of jade inner ring shoulder a very narrow gap, and can withstand high temperatures and high speed.  Shielded bearings with inner ring rotation of the main applications in working condition.  If the outer ring rotation bearings in high speed operation, it can cause grease leakage. 
 
 With a seal bearing
 bearings with contact seals, suffix 2RS1, O-ring is a steel skeleton of the anti-oil and anti-wear nitrile rubber set. 这 This allows the work of Xie seal temperature -40 to +100 ℃, in a short time up to +120 ℃. Contact the seal ring lip seal with the inner shoulder.  Seal the outer edge of the groove in the outer ring, in this location can provide a good sealing effect.
 When the sealed bearings running under certain extreme conditions, such as when high speed or high temperature, may result in grease in the inner ring and the seal leakage between.  If the leaks would cause damage of bearing configuration effects, use a need to go through a special design steps.
