Thin Section Bearings can be divided into three categories according to their material.For standard models, the bearing rings and rolling elements are made of high-carbon chromium bearing steel, which has stable mechanical properties.The corrosion-resistant model has stainless steel parts for some moving parts, making it suitable for highly corrosive working environments.Special operating condition models adopt a combination of materials, with bearing rings made of bearing steel and rolling elements made of ceramic.The matching retainer can be made of nylon or brass, each serving a specific purpose: isolation and guidance. The selection of materials is designed around different usage conditions, and the structural materials are clearly defined.

The precision of thin Section Bearings is divided into two levels: P5 and P4.The tolerances for the inner diameter, outer diameter, and width of P5 grade bearings are within the normal range, while the specified values for the roundness and cylindricity errors of the bearing rings are larger than those for P4.The P4 grade compresses the dimensional tolerance range and reduces the geometric error of the raceway.The P5 raceway profile deviation standard is more lenient, while the P4 raceway dimensional accuracy is higher.Both levels of precision have fixed tolerance standards, and all dimensions and geometric errors are controlled according to the corresponding level. The machining precision of the parts corresponds one-to-one with the level.The bearing precision can be selected according to different working conditions, taking into full account factors such as applicable range and cost performance.

The mass production of 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.Due to objective factors such as processing equipment and operating conditions, there may be slight deviations in the parameters of products in the same batch within the industry's allowable range, but the overall batch assembly can be stably adapted.
