S6005 CTA P4 UL GMN 25x47x12 Angular Contact Ball Bearing

Applications

The S6005 CTA P4 UL GMN angular contact ball bearing is designed for precision industrial applications where combined radial and axial loads occur together with high rotational speeds. Typical uses include machine tool spindles, high-speed drives, industrial automation, precision motors, and compact assemblies requiring stable axial shaft guidance within bearing housings or complete bearing units.

Design Advantages

This bearing features a CTA cage optimized for high-speed operation, ensuring stable ball guidance and low energy losses. The P4 precision class (equivalent to ABEC7) provides very high running accuracy, while UL preload allows correct operation in matched bearing arrangements. Compared to standard deep groove ball bearings, the angular contact design delivers higher system stiffness and improved axial load control. Manufactured by GMN, it offers high durability, low vibration, and consistent performance in demanding industrial environments.
