HZK Angular Contact Ball Bearings primarily support large, unidirectional axial loads. The larger the contact angle, the greater the load capacity. Cage materials include steel, brass, or engineering plastics, and molding methods include stamping or turning, depending on the bearing type and operating conditions. Other bearings include combined angular contact ball bearings, double-row angular contact ball bearings, and four-point contact ball bearings.
HZK Angular Contact Ball Bearings because the raceways of the inner and outer rings of angular contact ball bearings can move relative to each other on the horizontal axis, they can simultaneously withstand radial and axial loads—a combined load. (Single-row angular contact ball bearings can only withstand unidirectional axial loads and are therefore typically installed in pairs.) Cage materials include brass (ACM, BM), synthetic resin (AC), and steel (with an E suffix), depending on the bearing type and operating conditions.
HZK Angular Contact Ball Bearings are available in several types: 7000C (∝ = 15°), 7000AC (∝ = 25°), and 7000B (∝ = 40°). These bearings feature a locking collar on the outer ring, and the inner and outer rings are generally inseparable. They can withstand combined radial and axial loads, as well as unidirectional axial loads. The axial load capacity is determined by the contact angle; a larger contact angle increases the axial load capacity. These bearings can limit unidirectional axial displacement of the shaft or housing.
HZK Single-row angular contact ball bearings can only bear axial loads in one direction. When bearing radial loads, additional axial forces will be generated, and the corresponding reverse loads must be applied. Therefore, these bearings are generally used in pairs. Double-row angular contact ball bearings can bear large combined radial and axial loads and moment loads, mainly radial loads. They can limit the bidirectional axial displacement of the shaft or housing, and have a contact angle of 30 degrees.
HZK The characteristic of double row angular contact ball bearings is that they can bear the combined load of radial and axial loads at the same time, limiting the axial displacement of the shaft in both directions. Compared with double direction thrust ball bearings, this type of bearing has a higher limit speed, a contact angle of 32 degrees, good rigidity, and can withstand large overturning moments. It is widely used in the front wheel hubs of cars.
HZK Angular Contact Ball Bearings primarily withstand large unidirectional axial loads. The larger the contact angle, the greater the load capacity. Cage materials include steel, brass, or engineering plastics, and are formed by stamping or turning, depending on the bearing type and operating conditions. Other types include combined angular contact ball bearings, double-row angular contact ball bearings, and four-point contact ball bearings.
