7002 ACE/P4A Bearing Product Overview & Core Advantages
The 7002 ACE/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. This P4 (ABEC-7) tolerance class bearing is preloaded and pre-lubricated, enabling it to handle significant combined loads (radial and axial) simultaneously. Its compact design, featuring a 15 mm bore and 32 mm outside diameter, makes it ideal for space-constrained, high-speed machinery where high rigidity and operational reliability are paramount.
