Two major sealing methods for stainless steel bearings

In a special production environment, many stainless steel bearings are equipped with corresponding sealing devices. On the one hand, it keeps the grease (oil) inside the stainless steel bearing from being lost during use and ensures that the bearing is in a lubricated state. On the other hand, it protects dust or harmful gases/liquids outside the bearing from entering the inner cavity of the stainless steel bearing, preventing damage to the bearing. The following editor will explain the sealing method of stainless steel bearings to you.

1. Non-contact sealing refers to the gap between the sealing ring and the rotating shaft. The smaller the gap, the better the sealing effect, but the smaller the shaft speed is allowed, and vice versa.

2. Contact sealing, that is, there is no gap between the sealing ring and the rotating shaft. The larger the contact area of ​​the sealing ring contacting the outer ring, the better the sealing effect, but the smaller the shaft speed is allowed, and vice versa.

The above are some of the sealing methods of stainless steel bearings explained by the editor. I hope it will be helpful to you. If you still don’t understand, please continue to pay attention to our website.
