Sealed core ball bearing

Ball bearings also have a seal, its contact seal on both sides of the bearing - type suffix. These thin-steel reinforced seals are made of oil-resistant and abrasion-resistant acrylonitrile polybutylene (NBR) rubber. These seals allow operating temperatures ranging from minus 40 to +100 degrees Celsius, or up to 120 degrees Celsius for a short period of time. The sealing lip contacts a smooth chamfer on the inner ring in a light pressure manner. The standard seal bearings are lubricated by grease with lithium - based thickeners and have good antirust and other properties. MT33 or MT47 grease is used in the calculation of grease life similar to that of single row deep groove ball bearings. Note: sealed bearings are lubricated for life without maintenance. No heating over 80 degrees centigrade or washing before installation.
