Our 7005 7008 7010 series angular contact ball bearings are the cornerstone of high-speed CNC spindle technology, designed to provide extreme rotational accuracy and thermal stability. These bearings feature a defined contact angle (typically 15?? or 25??) that allows them to support significant axial loads in one direction while maintaining high radial capacity. Manufactured to P4 and P2 precision standards, they ensure that machine tool spindles operate with minimal runout, which is essential for achieving superior surface finishes on machined parts. We use high-strength phenolic resin cages that are specifically designed to minimize heat generation at high RPMs, preventing thermal expansion of the shaft. The balls are precision-matched to ensure even load distribution across the raceway. These bearings are often used in duplex or triplex arrangements (DB, DF, or DT) to provide the necessary axial stiffness for milling and grinding operations. Every 70 series bearing is tested for vibration and high-speed stability in our specialized lab. For manufacturers of woodworking machinery, high-speed carving spindles, and precision grinders, these angular contact bearings offer the reliable, long-lasting performance required to maximize productivity and machine uptime.
