| High Light | High Precision 5203 Ball Bearing ，5203-2RS Ball Bearing ，Machinery Angular Contact Ball Bearing | ||
5203-2RS is a premium double row angular contact ball bearing designed for high-precision, high-speed rotation scenarios, integrating exceptional rigidity and stable load-bearing performance. As a standard double row angular contact bearing model, its 17mm ID * 40mm OD * 17.5mm Width compact dimensions perfectly fit small-to-medium precision mechanical structures. The "2RS" designation denotes double-sided rubber seals, providing superior dustproof, moistureproof, and contaminant-resistant protection—extending service life in industrial, automotive, and precision equipment environments. Crafted from GCr15 high-quality bearing steel, it undergoes precision grinding and superfinishing, ensuring low friction, minimal vibration, and consistent rotational accuracy. The double-row structure significantly enhances radial load capacity and bidirectional axial load resistance, making it a core component for high-demand precision transmission systems.
CNC Machine Tool Spindles, Precision Machining Equipment, High-Speed Electric Motors, Automotive Auxiliary Components, Robotic Joints, Precision Gearboxes, Optical Processing Machinery, Medical Equipment Rotation Mechanisms, and other scenarios requiring high-precision double row angular contact bearings, dustproof high-speed bearings, or bidirectional load-bearing precision components
5203-2RS Double Row Angular Contact Ball Bearing (interchangeable with bearings matching "17x40x17.5mm size + double row angular contact + 2RS double-sided rubber seal + precision grade" specifications, such as SKF 5203-2RS, NSK 5203-2RS, INA 5203-2RS, Timken 5203-2RS brand-equivalent precision bearings)
