What are the Characteristics of the Sealing Structure of Single Row Deep Groove Ball Bearings?

Compared to standard contact seal bearings of single row deep groove ball bearings, light contact seal ball bearings have the following characteristics:

1) The interference between the seal and the inner ring is small, because the seal lip is slender, the seal lip pressure is reduced, and the torque is lower.

2) The seal lip is in contact with the outer slope of the seal groove of the inner ring, and the grease is splashed outward under the action of centrifugal force, so the dustproof performance is excellent.

3) Since the sealing lip touches the outer bevel of the sealing groove of the inner ring, the pressure inside the bearing is not easy to escape from the sealing lip, so it is not easy to occur the phenomenon of grease leakage.

● The main properties of sealed bearings of single row deep groove ball bearings

Sealed bearing performance includes: grease storage performance (anti-leakage performance), dustproof, waterproof, vaporproof performance, temperature rise performance, friction torque performance, vibration and noise performance, etc., but a variety of equipment generally require sealed bearings with good grease storage performance, dustproof performance and temperature rise performance, these three properties for the basic performance of sealed bearings, its merits and demerits directly affect the bearing life, but also the current domestic standards To test the important items of assessment.

1. Grease storage performance (anti-grease leakage performance)

The ability of sealed bearings to save grease in the bearing cavity after a certain period of operation.

2. Dustproof performance

The ability of sealed bearings to prevent dust from penetrating into the bearings during operation.

3. Temperature rise performance

Sealed bearing in certain conditions of operation, its outer ring surface temperature higher than the ambient temperature degree.
