The commonly used sealing structure for thin Section Bearings is contact sealing, with rubber seals being the mainstream.The seals are assembled on both sides of the bearing to prevent dust, moisture, and particulate matter from entering the interior, while also preventing grease leakage.Different sealing styles are matched to different working conditions. Standard sealing structures are used for normal working conditions to meet basic protection requirements.The sealing structure fits tightly with the outer and inner rings of the bearing, with standardized clearance control, which can maintain sealing performance for a long time and is suitable for most conventional operating environments.
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.
