Angular Contact Ball Bearing
TFL offers the most comprehensive range of angular contact ball bearings. The contact angle of angular contact ball bearings can withstand large axial and radial loads in one direction. In addition, because of the axial component generated when the radial load is applied, these bearings are usually used in pairs, triples, quadruples or groups.
What is an Angular Contact Ball Bearing?
Angular contact ball bearings have raceways on the inner and outer rings. The inner and outer rings can be relatively displaced along the bearing axis. This type of bearing is particularly suitable for bearing compound loads, that is, loads acting both radially and axially. The axial load-bearing capacity of angular contact ball bearings increases with the contact angle α. The contact angle is the angle between the line of contact points between the ball and the raceway in the radial plane and the vertical line of the bearing axis.
Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, the additional axial force will be caused. And it can only limit the axial displacement of the shaft or housing in one direction. Angular contact ball bearings have a contact angle of 40 degrees to withstand large axial loads. Angular contact ball bearings are of a non-separable design. The shoulders on both sides of the inner and outer rings are different in height. To improve the load capacity of the bearing, the shoulder on one side will be processed lower so that the bearing can be loaded with more steel balls.
Double row angular contact ball bearings can withstand larger radial loads, mainly combined radial and axial loads and moment loads, limiting the axial displacement of the shaft on both sides. The tiltability between the inner and outer rings of the double row angular contact ball bearing is mainly used to limit the bidirectional axial displacement of the shaft and the housing. The allowable tilt angle depends on the internal clearance of the bearing, bearing size, interior design, and acting on it. The force and moment on the bearing and the maximum allowable inclination angle should ensure that no excessive additional stress is generated.
What Are Thrust Ball Bearings Used For?
Single row angular contact ball bearings can only bear axial load in one direction. TheThe additional axial force will be caused when bearing radial load when bearing radial load, and corresponding reverse gear must be applied. Therefore, these kinds of bearings are generally used in pairs.
Single row angular contact ball bearings are often used in the following applications: machine tool spindles, high-frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts, booster pumps, drilling platforms, food machinery, substations Degree head, repair welding machine, low-noise cooling tower, electromechanical equipment, painting equipment, machine tool slot plate, arc welding machine.
The double row angular contact ball bearings are characterized in that they can simultaneously bear the combined load of radial and axial loads and limit the axial displacement of the shafts on both sides. Compared with two-way thrust ball bearings, this kind of bearing has a higher limit speed, a contact angle of 32 degrees, good rigidity, and can withstand a sizeable overturning moment. It is widely used in the front wheel hubs of cars (some models also use the same size Double row tapered roller bearings).
Double row angular contact ball bearings are often used in the following applications: oil pumps, roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery, planetary reducers, extraction equipment, cycloid reducers, food packaging machinery, Electric welding machine, electric soldering iron, square box, gravity spray gun, wire stripping machine, half shaft, inspection and analysis equipment, delicate chemical machinery.
