Sealing Device

The sealing device is designed to prevent external substances from entering the interior of the bearing, while also preventing the leakage of internal lubricating oil or grease. Common sealing devices include the following:

1. Metal cover sealing: usually used for low-speed bearings, with poor sealing performance and easy contamination.

2. Rubber seal: commonly used in high-speed bearings, with good sealing performance, but prone to aging.

3. Coil spring seal: usually used for high-speed bearings, with good sealing performance, but requires precision machining.

4. Groove sealing: Usually used for low-speed bearings, it has good sealing performance but requires high surface roughness.

5. Magnetic seal: Usually used for high-speed bearings, it has good sealing performance but requires high manufacturing costs.

The selection of sealing device should be based on the operating environment and requirements of the bearing, and a suitable sealing device should be chosen to ensure the normal operation of the bearing
