KP-BS Series and MKP-BS Series Bearings
KP-BS series bearings are single row, radial-type airframe control bearings. MKP-BS products are precision bearings. ABEC tolerances.
KP-BS Series Bearings
- Manufactured to AS27648 per SAE AS7949
- External self-aligning single row ball bearing
- Installed with PTFE 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 Bearings
- Precision Series tolerances in light blue
- When ordering precision parts be sure to add the “M” prefix to the standard part number
