SKF 71920 ACBGA/HCP4AL Supernatančni, za visoke hitrosti izvedba B, univerzalno združljiv enoredni kroglični ležaj s poševnim dotikom primeren za neposredno mazanje olje-zrak

These super-precision, high-speed, single row angular contact ball bearings with 15° or 25° contact angle accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. Compared to the equivalent SKF E design high-speed bearings, these are suited for lighter loads. Being universally matchable, they can be used together in arrangements to provide effective load sharing, within a predetermined preload range, without the use of shims or similar devices. They have two lubrication holes, an annular groove, and two annular O-ring grooves in their outer rings.
