KSP Series and KSP-A, MKSP, and MKSP-A Series Bearings
KSP series and KSP-A, MKSP, and MKSP-A series bearings are self-aligning, single-row airframe control bearings with ABEC tolerances.
KSP Series Bearings
- Self-aligning single row ball bearing
- Manufactured to AS27645 per AS7949
- All external surfaces except bore and stainless steel seal retainers are cadmium plated
- Installed with PTFE seals
- Pre-lubricated (see grease specifications)
- Warning: Do not allow these bearings to act as misalignment stops!
