1203 P/6 Bearing Product Overview & Core Advantages
The 1203 P/6 is a precision double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined radial and axial loads. Featuring an open design with optimized internal geometry, this metric bearing delivers exceptional rotational accuracy and stability. Its compact dimensions (17mm bore × 40mm OD × 12mm width) make it ideal for space-constrained installations while maintaining robust load carrying capacity. Manufactured with chrome steel components and nylon cage, it offers excellent durability and smooth operation at high speeds up to 24,000 rpm.

1203 P/6 Bearing Structural Features & Performance Benefits
Double Row Design: The two rows of balls arranged at optimal contact angles provide high rigidity and superior moment load capacity compared to single row bearings, making it ideal for applications requiring precise shaft positioning.
Enhanced Load Capacity: With a radial dynamic load rating of 1989 lbf and static rating of 495 lbf, this bearing effectively handles combined radial and axial loads in both directions, ensuring reliable performance in demanding operating conditions.
High-Speed Performance: The nylon cage minimizes friction and allows for smooth operation at limiting speeds of 24,000 rpm. The open construction facilitates efficient lubrication management for sustained high-speed applications.
Precision Engineering: Manufactured to CN radial internal clearance standards with tight dimensional tolerances (bore: -0.008mm to 0), ensuring consistent performance and extended service life in precision machinery.
