6268, 61972 Deep Groove Ball Bearings For Motors, Instrument With Arc Groove Form

 

Feature:

They are the most typical rolling bearings with extensive applications. The raceways in both of the rings are in arc groove form, which can carry radial and axial load in double directions. They can be applied in situations where high-rotating speed and low noise and low vibration are required.

 

Cages:

Deep groove ball bearings generally use pressed cages of steel sheet or brass cages. When the outer diameter is less than (inclusive)400mm, they use pressed cage with steel sheet. When the outer diameter is bigger than 400mm, they use brass cages.

 

Applications:

Can be found in automobiles, machine tools, motors, instruments, construct machines, railway vehicles, agricultural machines and various other special machines

 

Types:

Basic type, With snap ring groove on the outer ring(-N), With one shield(-Z) on one side or two shields(-2Z) on both sides, With one seal(-RS)on one side or two seals(-2RS)on both sides.
