KD-XP0 Four-Point Contact Thin-section Bearing Preloaded Precision Slewing Bearing

KD-XP0 series Thin Section Bearings

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 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.
