Open Radial Contact Deep Groove Equal Cross-section Bearings KF-CP0 Series
KF-CP0 is an open C-type radial contact deep groove ball bearing, The cross-section is always 19.05mm. Its core features are equal cross-section thin-wall design, lightweight, compact size, and low friction torque. It mainly bears radial loads and is not suitable for large cover torque and large thrust conditions.

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.
Due to their stable precision and structure, thin Section Bearings are widely used in industrial and civil sectors. In the field of electromechanical power, it is widely used in the spindles and power transmission components of various small and medium-sized motors; in the field of automation, it is applied to assembly line transmission units, precision motion modules, and moving joints of intelligent equipment. In the fields of civil and general machinery, it is compatible with ventilation equipment, water supply pumps, and transmission structures of household appliances. Different precision levels can be selected as needed, with strong overall compatibility. The protective structure can cope with normal field environments and meet the requirements for long-term continuous operation of the equipment.
