kP-BS Series Self-Aligning Torque Tube Type

Control Bearings
KP-BS Series
Self-Aligning Torque Tube Type
MS27648. MIL-B-7949

Single row, ball, external self aligning.
Equipped with Teflon seals.
Exposed surfaces except bore, cap, and seals are cadmium plated.
Prelubricated. (See Table 1, page 111 for options.
Series is internally identical to the KP-B series. Self-alignment is
provided by an external self-aligning ring whose internal
sphericallyground surface is accurately matched to the external sphericallyground surface of the outer ring. These bearings are designed to compensate for initial misalignment.
