7007 ACE/P4A Bearing Product Overview & Core Advantages
The 7007 ACE/P4A is a single-row angular contact ball bearing engineered for high-precision and high-speed applications. Designed to accommodate combined loads (radial and axial loads in one direction), it features a 25° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it delivers exceptional running accuracy and rotational stability. Its phenolic resin cage and factory-applied lubrication contribute to smooth operation at its high limiting speed of 46,000 rpm, making it an ideal choice for demanding, precision machinery.
