7009 ACE/P4BVG275 Bearing Product Overview & Core Advantages
The 7009 ACE/P4BVG275 is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. Engineered to a P4 (ABEC-7) tolerance class, this bearing is optimized to handle combined loads—simultaneously supporting significant radial and axial loads. Its 25° contact angle provides superior axial load capacity and high rigidity, making it ideal for high-speed spindles and precision machinery. The phenolic cage and pre-lubrication contribute to its smooth operation and long service life in a wide temperature range from -30°C to 110°C.
