Two Row Angular Contact Ball Bearing3324M 120 X 260 X 106mm For Cement Pump

 Two row angular contact ball bearing3324M 120 X 260 X 106mm for cement pump

The ball bearing 3324m belongs to high precision contact ball bearing that will use cement sugar and other industry machine. The bearing we had batch stock for customer urgent need them.
We can offer the design drawing service and offer the sample to test the quality.
We had manufacture the angular contact ball bearing 3324m with size 120*260*106mm for pump equipment. The spare part including one outer ring and inner ring and ball and brass .the bearing will bear high load and lower speed. All the dimension tolerance will be meet the customer machine requirement.

Now the bearing 3324M with brass cage data as following:

The bearing 3324m actual picture as following:

Angular contact ball bearings
Angular contact ball bearings have high limiting speed, and can carry radial and axial loads at the same time.

1. Single-row angular contact ball bearings
Single-row angular contact ball bearings can only carry pure axial loads in one direction,and the capacity increases with contact angle. The nominal contact angles are 15°, 25° and 40°. When the bearings carry radial loads, the inner and outer rings will be separated because of additional axial force. They are normally mounted in pairs.
Single-row angular contact ball bearings have two structures: separable and non separable, because of more balls in bearings, high loading capacity and stiffness can be gained.
The basic type of separable angular contact ball bearings is type S70000. Type SN70000 have separable inner ring, and the inner and outer rings can be mounted respectively when the installation conditions are restricted.

2. Double-row angular contact ball bearings
Double-row angular contact ball bearings are nonseparable. They can carry combined loads which is main in radial and moment loads, and limit axial displacement of shafts or housings in two directions, the nominal contact angle is 30°,they have higher stiffness comparing with single-row bearings. They correspond to a pair of single-row angular contact ball bearings mounted back to back, but the width is narrower.Therefore, they are especially suitable for applications required high stiffness.
Double-row angular contact ball bearings usually have fitting slot, the side of the raceway without fitting slot must carry main loads when bearings are in use.
The obliquity is limited between inner and outer rings of double-row angular contact ball bearings, the permissible slant angles depend on the internal clearance, dimensions, internal design, the forces and the moments of the bearings. It must be ensured that higher additional stress can’t be formed in bearings when the permissible slant angle is maximum. The bearing life will be shortened ,the running accuracy will be reduced and the noise will be increased if there was slant angle between inner and outer rings.Nylon or brass solid cages are generally used in double-row angular contact ball bearings.
