HD90149326033 Four-Point Contact Ball Bearing Product DescriptionI. Product Features1. Optimized core structure, adopting a detachable design of split inner ring + integral outer ring. Each steel ball theoretically forms four contact points with the raceways of the inner and outer rings, which conforms to the core design principle of four-point contact ball bearings. It can stably bear bidirectional axial loads, and at the same time can bear a certain radial load and moment load, adapting to the needs of multi-directional load working conditions.2. The raceway adopts a special Gothic arc design, which is precision ground with high surface smoothness. The standard contact angle is designed to be 35°, and the axial clearance can be independently defined without changing the fit between the raceway and the steel ball, ensuring uniform load transmission, reducing local stress concentration and lowering the risk of wear.3. The core components are made of high-purity bearing steel and undergo a strict heat treatment process, with high hardness and strong toughness. Combined with precision machining technology, they have excellent wear resistance, fatigue resistance and impact resistance, can adapt to complex working conditions such as high and low temperatures and high-speed operation, are not easy to deform or damage, and extend the service life.Equipped with an outer ring guided cage, optional brass or PEEK high-temperature resistant material, with a solid structure and smooth rotation. It can evenly separate the steel balls to avoid friction and collision between the steel balls, and at the same time improve the overall operation accuracy of the bearing, adapting to high-speed operation scenarios and reducing operation noise and heat generation.5. Detachable inner ring design: the inner ring can be installed separately from the outer ring and the steel ball cage assembly, which is convenient for the installation, disassembly and later maintenance of the equipment, greatly reducing maintenance man-hours and difficulty, adapting to on-site rapid maintenance needs. At the same time, the special chamfer design of the inner ring can improve the oil circuit and reduce deformation caused by axial clamping.6. Excellent sealing performance, which can effectively block the intrusion of dust and impurities, prevent lubricating oil leakage, and ensure the long-term stable operation of the bearing under complex working conditions with high dust and high load. Before leaving the factory, it has undergone strict precision testing, load testing and speed calibration, with strong performance consistency, no obvious noise during operation, no jamming phenomenon, extremely low failure rate, and meets the requirements of industry quality standards.7. Compact structure, the axial space occupation is significantly lower than that of double-row angular contact ball bearings, which is equivalent to the composite function of two sets of back-to-back angular contact ball bearings. It can be flexibly adapted to equipment with limited axial space without additional adjustment of the installation position, and has stronger adaptability.II. Product Specifications1.
