KF-XP0 Large-section Four-point Contact Bearing for Large Automated Slewing Mechanisms

KF-XP0 series bearing

Three main materials are used for thin Section Bearings.The standard model features high-carbon chromium bearing steel for the inner and outer rings and rolling elements, making it suitable for conventional drying conditions.The corrosion-resistant version features stainless steel inner and outer rings and rolling elements, making it suitable for humid and corrosive working environments.The ceramic hybrid version adopts a composite structure, with the inner and outer rings made of bearing steel and the rolling elements made of ceramic material, making it suitable for special working conditions such as high speed, low friction, and high temperature resistance.All cages are typically made of nylon or brass and are responsible for separating and positioning the rolling elements, providing structural support for stable bearing operation.

The precision of thin Section Bearings is mainly P5 and P4 grades.The radial and axial run-out specifications for P5 are larger than those for P4, making it suitable for normal operating scenarios.The P4 grade strictly reduces radial and axial run-out errors, resulting in smaller rotational position deviations.The P5 end face and raceway fit accuracy requirements are relatively low, while the P4 has higher requirements for the rotational concentricity after assembly.The two levels of accuracy indicators are clearly distinguished, and the factory tests and judges them according to the corresponding run-out parameter standards.
