SKF QJ 203 N2MA/C2L Single Row Four Point Contact Ball Bearing 17 mm ID, 40 mm OD, 12 mm Race Width Austria

The SKF QJ 203 N2MA/C2L is a high-performance single row four point contact ball bearing manufactured in Austria, engineered to support combined radial and axial loads in compact and precision rotary assemblies. With a 17 mm inside diameter, 40 mm outside diameter, and a 12 mm race width, it is optimized for applications that demand high-speed operation up to 30000 rpm.

This bearing features a C2 internal clearance that improves axial stiffness when under load, along with a 35° contact angle which effectively distributes axial forces, allowing the bearing to sustain thrust in both directions. The machined metal cage ensures consistent ball spacing even at high rotational speeds, while the use of steel balls provides dependable rolling-contact performance and extended service life.

With an open end design and parallel bore, the bearing permits straightforward axial positioning directly onto shafts. It is highly suitable for compact motor spindle assemblies, precision rotary indexing units, small gearbox shafts requiring axial load support, and high-speed pump rotor bearings, making it versatile for industrial, manufacturing, and mechanical applications.

Maintaining rotation speeds at or below the 30000 rpm limiting speed will ensure long service life and optimal performance. This bearing is essential for engineering solutions requiring precise combined load handling and high rotational speed capabilities.
