This spindle bearing is a single-row angular contact type with a contact angle of 25°, designed for adjusted mounting in pairs or sets. Bore diameter is 20.0 mm, outside diameter 37.0 mm, width 9.0 mm, and net mass 38.0 g. It features a solid cage (T) and non-contact lip seals fitted on both sides, keeping friction low while protecting the raceways from contamination. Manufactured to restricted (P4S) tolerances, this bearing suits applications requiring precise shaft guidance with minimal internal clearance and consistent axial preload when used in matched pairs or sets. The 25° contact angle allows it to carry combined loads, while the built-in seals permit operation without external sealing arrangements. Its dimensional accuracy and cage design support stable performance at the elevated rotational speeds typical of precision spindle arrangements.
