Product Overview and Core Advantages
The 7072 is a single row angular contact ball bearing designed for applications requiring high precision and the ability to accommodate significant axial loads in one direction. With a 40° contact angle and manufactured to a P6 (ABEC-3) tolerance class, this bearing delivers exceptional running accuracy and rotational stability. Its robust construction, featuring chrome steel rings and a brass cage, ensures reliable performance in demanding industrial environments. The open design allows for versatile lubrication options, making it suitable for high-speed operations up to 1,200 rpm.
