KOYO High-rotating Speed 6404 2RS ZZ 20x72x19mm Deep Groove Ball Bearing

High-rotating Speed 6404 bearing Deep Groove Ball Bearings 6404 6404-2RS 6404-2Z

The 6403 bearings feature deep, honed raceways, resulting in a perfectly balanced bearing can be used in a wide range of applications witch need to carry both radial and axial loads. There have four types are available, OPEN type (No shields), ZZ type (Metal shields), 2RS type (Contact rubber seals), 2RZ (Non-contact rubber seals).

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.
