7200A Angular Contact Ball Bearing which were used for cars,compressors, construction, electric motors, food industry, home appliances etc.
Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously supporting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. Retainers are made of brass ,synthetic resin of others subject to individual bearing features and application conditions.
It uses axially asymmetric races. An axial load passes in a straight line through the bearing, whereas a radial load takes an oblique path that tends to want to separate the races axially. So the angle of contact on the inner race is the same as that on the Tycontact angle of the bearing should be matched to the relative proportions of each. The larger the contact angle (typically in the range 10 to 45 degrees), the higher the axial load supported, but the lower the radial load.
1.Single-row angular contact ball bearings
Axial load in single direction can be sustained. While supporting pure radial load, the bearings must be installed and used in pairs since the line of action of the rolling element load is not in the same plane as that of the radial one, resulting in inner separate force.
2.Double-row angular contact ball bearings
This is basically a back-to-back mounting of two single-row angular contact ball bearings, but their inner and outer rings are each integrated into one. Axial loads in both directions can be sustained, and the capacity to sustain moments is good. This type is used as fixed-end bearings. Their cages are pressed steel.
3.Four-point angular contact ball bearings
The inner ring is split radially into two pieces. Their design allows one bearing to sustain significant axial loads in either direction. The contact angle is 35°, so the axial load capacity is high. This type is suitable for carrying pure axial loads or combined loads where the axial loads are high. The cages are made of machined brass.
They are mainly used for steel industry, mining& construction, papermaking machinery, wind turbines, semiconductors, machine tools, gearboxes, electric motors, pumps& compressors, injection molding machines.

C: Do you like accept small order bearing?
J: we enjoy to grow up together with all our clients, whatever big or small, you will become bigger and bigger to be with us.
C: What causes bearing noise?
J: Bearing noise is a function of both the bearing and the way it is used. Some external factors that affect bearing noise include lubricant type, excessive bearing load, and improper installation. Once the abnormal noise occurred, you can contact our engineers, we will help you find the reasons and provide the appropriate solutions.
C: What is your terms of payment ?
A: 100%T/T advance
B: 30% T/T in advance .70% against copy of B/L (For large order)
C: 50% in advance, the balance should be paid after seeing the picture of total goods.
E: Western union
F: Official Bank Account
C:Can I get some samples and do you offer the sample free?
J:sure, we are happy to send you samples.If we have stock, we can send you free sample.
And you just need to pay freight. If there have no stock, you need to pay sample fee and freight
