• Supplied new with full traceability documentation to support maintenance records

The MS27641‑10 / KP10A is a precision‑manufactured roller (ball) bearing intended for airframe applications where dependable, low‑friction rotation and contamination protection are required. Built to MS/AS27641 dimensional standards, this FAA‑PMA eligible replacement features robust materials and sealing to withstand typical aircraft operating environments. Dual PTFE contact seals retain MIL‑G‑81322 grease, protecting raceways from debris and moisture while minimizing maintenance intervals. Rings and balls are produced from aircraft‑grade chrome steel, hard‑turned to retain geometric accuracy and wear resistance under load.

This bearing is ideal for control linkages, bellcranks, and similar mechanisms on fixed‑wing and rotorcraft platforms. Always confirm fitment and applicability against your aircraft I.P.C. or PMA eligibility listing before installation.
