SKF Thrust Ball Bearing 51203, 17 mm ID, 35 mm OD, 12 mm Width, Open, 1 Row

The SKF 51203 thrust ball bearing is a precision-engineered component designed to provide efficient axial load support in a wide range of industrial, automotive, and aerospace applications. With a 17 mm inner diameter and a 35 mm outer diameter, it is optimized for installations that require a compact yet robust solution for axial guidance and rotation. Its open end type allows for easy visual inspection and lubrication access. The bearing features a single row of steel balls retained by a high-strength sheet metal cage, ensuring excellent performance even at high speeds or under elevated loads.

Constructed with durable steel races and balls, this bearing offers longevity and the ability to operate reliably in environments exposed to contaminants, vibration, or high operating temperatures. The precision ground bore facilitates an interference fit, enhancing shaft stability and reducing operational noise. Its separable design allows quick assembly, disassembly, and part replacement during preventive maintenance, minimizing equipment downtime and servicing costs.

The 51203 model is classified as an extra light series thrust ball bearing, featuring a 12 mm race width and a parallel bore. It provides an internal clearance of CN, making it suitable for general industrial settings where moderate clearance is acceptable. The unit supports static loads up to 27 kN and dynamic loads up to 16.3 kN, with a limiting speed rating of 9500 rpm - making it suitable for high-speed rotating equipment and assemblies demanding precise axial guidance.

Typical use cases include gearboxes, pumps, compressors, automotive transmissions, marine propulsion systems, and various machinery where axial loads need to be transferred efficiently. The robust build of the sheet metal cage ensures the bearing maintains its structural integrity under high pressure and temperature, while the high-grade steel balls resist environmental degradation and wear.

The plain race type, open end configuration, and standardized dimensions enable compatibility with existing equipment or direct replacement needs. This bearing is the preferred choice for those seeking reliable, easy-to-maintain thrust solutions in industrial and commercial operations. Whether used in original equipment manufacturing or maintenance and overhaul projects, SKF's commitment to quality assures optimal performance and operational longevity.
