KB090AR0 Angular Contact Thin-Section Ball Bearing for Semiconductor Inspection Workstations

The KB090AR0 is an open-type bearing with a 30° contact angle, featuring bearing steel rings, a brass cage, and precision steel balls. Featuring a lightweight, hollow structure, it offers excellent axial load-bearing capacity, smooth rotation with minimal resistance, and stable precision; it is widely used in industrial machinery, medical imaging equipment, and precision rotating equipment for the aerospace industry.

Slim Section Bearings are suitable for medium and small loads and medium and high speed operating conditions, covering a wide range of industrial and civil equipment.In the industrial sector, it is mainly used to support servo motors, stepper motors, automated transmission modules, testing instruments, and small conveying mechanisms; in the light industry sector, it is used for fans, water pumps, and drive components for home appliances.The P5 precision model is suitable for conventional transmission equipment, while the P4 high-precision model is mostly used in robot joints, precision instruments, and other structures with stringent requirements for rotational accuracy.The product features a mature sealing and lubrication design, enabling continuous operation in lightly dusty environments, and boasts a compact structure.

The narrow section bearing adopts a thin-walled integrated structure, which has light overall weight, low friction resistance during dynamic operation, and controllable temperature rise during high-speed operation. P4 and P2 high-precision models have extremely small radial and end face run-out, weak rotational vibration, and outstanding dynamic positioning stability. The bearing rolling elements are evenly distributed in force, can withstand continuous alternating loads, and are not prone to deformation. When used with lubricating media, it can form a uniform oil film, reduce rolling wear, and suppress operating noise. Its stable dynamic performance can support precision equipment to continuously start, stop, and rotate back and forth for a long time, and continue to maintain high-precision motion output.
