Description of single row bearing 7021C

The  Angular Contact Ball Bearing is designed to meet original equipment manufacturers' demanding requirements. These bearings have a contact angle  which enables them to withstand significant axial loads in one direction 

together with radial loads. They are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets since an axial component is generated when a radial load is applied.

Product Features and Benefits of Angular Contact Ball Bearing 

· High Quality Steel - Ultra clean steel to extend bearing life by up to 80%.

· Advanced Grease Technology -  lubricants that can extend grease life and performance.

· High Grade Balls - Quiet and smooth operation even at high speed.

· Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life.

· Contact Angle - Offered in 15, 25, 30 and 40 degree angles.

· Patented Seals - Provide resistance to contamination in the toughest environments.

Angular contact ball bearings can bear not only axail but also radial loading capacity.Though only bearing unilateral axial loading capacity, they can be used together with the bearings bears opposite axial loading capacity. Angular contact ball bearings, with a limit ability to self-aligning, can not be dismantled.

Main products 

Angular contact ball bearing type:

Single row angular contact ball bearing: only carry a direction of the axial load, when in bear radial load, can cause additional axial force must be applied to the corresponding reverse load, therefore, the bearings are generally used in pairs.

Double row angular contact ball bearing: At the same time can bear radial and axial load joint load, limit shaft on both sides of the axial displacement.

Angular contact ball bearing main technical indicators:

(1) Bearing precision index: More than GB / 307.1-94 P4 level accuracy

(2) High-speed performance index: 1.3~1.8x 106 /min

(3)Service life:more than 1500h

Feature:
1) Load capacities are higher than deep groove ball bearings of same dimensions
2) Used for bearing radial-axial combined loads or pure thrust loads
3) Low operating friction and high limiting speed

Type:
1). Single row angular contact ball bearings
2). Double row angular contact ball bearings
3). Four-point contact ball bearings

Mounting
