KP-BS Series

Single Row Radial
Aircraft Control Bearing

• Manufactured to AS27648 per SAE AS7949
• External self-aligning single row ball bearing
• Installed with Teflon® seals
• All external surfaces except bore and stainless steel seal retainers are cadmium plated
• Pre-lubricated
• Designed to compensate for initial misalignment, the KP-BS series is internally identical to the KP-B series on the previous page. Self-alignment is performed by an external self-aligning ring whose internal spherically-ground surface is accurately matched to the external spherically-ground surface of the outer ring.

MKP-BS Series

• Precision Series tolerances in light blue
• When ordering precision parts be sure to add the "M" prefix to the standard part number
