Vacuum Cleaner  Bearing  7224C

Due to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing

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
