KG-XP0 Precision Slim Thin Section Bearing with High Running Accuracy
The KG-XP0 series is a four-point contact Reali-Slim thin section bearing series with a constant cross-section design of 25.4 × 25.4 mm. Its lightweight and compact design enables it to accommodate radial, axial and moment loads simultaneously, while offering high stiffness, low friction and high running accuracy. They are widely suitable for space-constrained rotating applications, such as robot joints, precision rotary tables, automation equipment and optical instruments.

The mainstream material of thin section bearing rings and steel balls is GCr15 bearing steel, which has high hardness and excellent wear resistance after heat treatment. Corrosion usage scenarios are made of 440C stainless steel, which has strong anti-rust ability and can meet the needs of humid and medium-containing working environments. The material selection of rolling elements and rings should be consistent to ensure that the materials of friction pairs are uniform. Cages are divided into two categories: brass and engineering plastics. The brass material is wear-resistant and not easy to deform, while the plastic material is light in weight and has low operating noise. The thermal expansion coefficients of all supporting materials are compatible with each other and adapt to the thin-walled structure of the bearing to ensure stable operation of the bearing.
The mainstream precision grades for thin Section Bearings are P4 and P5.The inner diameter, outer diameter, and width tolerances of P5 grade bearings are within the normal range, and the raceway form and position deviations, radial and axial run-outs meet general usage requirements.P4 grade is a high-precision specification with narrower dimensional tolerances, higher raceway geometric accuracy, and significantly reduced radial and axial run-out.The two grades of parameters are clearly defined, and all accuracy indicators are implemented in accordance with the specifications, ensuring a high degree of uniformity in the accuracy performance of bearings of the same grade.
