KAA15AG0 38.1*47.625*4.763mm Thin Section Angular Contact Bearings

Thin Section Bearings are extra thin section bearings, with square cross-sections for both inner and outer rings, and the cross-sectional dimensions are consistent. The whole is composed of an inner ring, an outer ring, rolling elements, and a retaining structure. Based on the raceway form, there are three types of structures: deep groove ball, angular contact, and four-point contact, most of which are open designs. Cages are used to separate and hold rolling elements in place. The angular contact structure has a fixed contact angle and can withstand radial and unidirectional axial loads; the four-point contact structure can withstand bidirectional axial loads. The bearings have uniform wall thickness, compact shape, small installation space, and are suitable for various precision automated equipment.

Thin section bearings are suitable for medium and small loads and medium and high speed operating conditions, covering a wide range of industrial and civil equipment. In the industrial sector, it is mainly used to support servo motors, stepper motors, automated transmission modules, testing instruments, and small conveying mechanisms; in the light industry sector, it is used for fans, water pumps, and drive components for home appliances. The P5 precision model is suitable for conventional transmission equipment, while the P4 high-precision model is mostly used in robot joints, precision instruments, and other structures with stringent requirements for rotational accuracy.

The mass production of constant thin section bearings adopts a full-process quality control system, with inspection covering parts processing, assembly and finished product delivery. After components such as raceways and rolling elements are processed, their dimensional tolerances, roundness, cylindricity, and other geometrical indicators are inspected, and they are classified into P4 and P5 accuracy grades according to standards. During the assembly stage, process inspections are set up to control the fit clearance. After the finished product is greased and sealed, the rotation accuracy, operating noise and flexibility are sampled and tested according to the standard ratio. Some batches will have samples taken for short-term durability testing.
