Bearing seal is on the outside of the bearing, such as bearing shell parts and diameter of axle parts and end cover part of the additional sealing device.

Should be considered in selecting bearing sealing device, a kind of lubricant bearing (fat or oil), the sealing contact surface of rotational speed, supporting installation error, and many other factors.Low requirements for sealing, bearing high rotational speed and shaft installation error and slants big, can choose non-contact sealing device.Non-contact sealing device can be divided into ptfe soft belt bearing use seal clearance and the use of centrifugal force LiangWu oil self-lubricating composite bearing types.If you want to enhance the sealing effect, can be added in the non-contact centrifugal or stagnation pieces, using centrifugal force to control the discharge of the grease in order to achieve sealing effect.If bad work environment, the possibility of moisture infiltration or bearing lubrication oil bearing parts can choose contact self-lubrication thrust gasket sealing device.Contact sealed devices typically have oil seal, grease seal, mechanical seal, etc.
