7068 BGM Bearing Product Overview & Core Advantages
The 7068 single row angular contact ball bearing is a precision bearing engineered for applications demanding high rigidity and accurate rotational performance. Its defining characteristic is the 40° contact angle, which enables it to efficiently support combined loads—significant radial loads acting in conjunction with substantial axial loads in one direction. Manufactured to a P6 (ABEC-3) tolerance class, it guarantees exceptional running accuracy, making it a reliable component for high-performance machinery. The open design, combined with a robust brass cage, facilitates high-speed operation, with a limiting speed of 1,300 rpm.
