Two matched ultra-precision, high-speed, E-design single row angular contact ball bearings
These two ultra-precision, high-speed, E-design matched single row angular contact ball bearings are available in a variety of configurations. Compared with the same SKF B-type high-speed bearing design, its rotational speed capability is slightly higher and it can withstand higher loads.
