Roller Bearing – Airframe Ball Bearing FAA-PMA Replacement | MS27641-10 KP10A
Roller Bearing – Airframe Ball Bearing | FAA‑PMA Replacement MS27641‑10 KP10A
New, fully traceable MS27641‑10 (KP10A) airframe ball bearing — FAA‑PMA eligible replacement, sealed and grease‑packed for reliable aircraft control and linkage applications.
- FAA‑PMA eligible replacement for MS27641‑10 (KP10A)
- Pre‑lubricated with MIL‑G‑81322 grease and double‑contact PTFE seals for long service life
- High‑strength chrome steel rings & balls (E52100), heat‑treated for wear resistance
- Cadmium plating on exposed surfaces and stainless steel retainer for corrosion protection
- Designed for airframe control linkages, bellcranks, and moderate‑duty applications
- 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. Fully traceable and supplied new, 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.
