Type Of Deep Groove Ball Bearing

1. Deep Groove Ball Bearing With Dust Cover
Generally Used In The Single Lubrication Is More Difficult, The Placement Of Lubricating Oil And Check The Lubrication Is Not
Convenient Conditions, Usually Injected Into The Bearing Rust, Lubrication Dual-Purpose Lithium Grease Is 1/4 To 1/3 Of The
Bearing Internal Space.

2. Deep Groove Ball Bearing With Sealing Ring
Its Performance, Grease Filling, Use And Bearing With Dust Cover Are Basically The Same, The Difference Is That There Is A Large
Gap Between The Dust Cover And The Inner Ring, And The Sealing Lip And The Inner Ring Of The Non-Contact Seal Ring Is Small, There
Is No Gap Between The Sealing Lip And The Inner Ring Of The Contact Seal Ring Bearing, The Sealing Effect Is Good, But The
Friction Coefficient Has Increased.

3, There Are Stop Groove And Deep Groove Ball Bearings With Stop Ring
In Addition To The Function Of Bearing Radial Load, The Deep Groove Ball Bearing With The Stop Ring Can Also Limit The Axial
Displacement Of The Bearing, Simplify The Structure Of The Bearing Seat And Reduce The Bearing Size. Generally Used In Cars,
Tractors And Other Axial Load Is Not Large Working Parts.

4. Deep Groove Ball Bearing With Ball Filling Gap
There Are Notches In The Inner And Outer Rings On One Side, From Which More Balls Can Be Loaded, Increasing Its Radial Load
Capacity. However, Due To The Small Axial Load Capacity, It Can Not Run At High Speed. If There Is A Large Axial Load, It Needs To
Be Used With The General Deep Groove Ball Bearing.
