SKF S71909 ACBGA/HCP4A Super-precision, high-speed, B design, universally matchable single row angular contact ball bearing with seals

These super-precision, high-speed, B design, single row angular contact ball bearings, with seals, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. They are designed to accommodate very high speeds and, non-contact compared to SKF E design high-speed bearings, are best suited for lighter loads and lower operating temperatures. Being universally matchable, they can be used together in arrangements to provide effective load sharing, without the use of shims or similar devices.
