MS27641‑6 (KP6A) airframe ball bearing with 0.375" ID and 0.875" OD. New, fully traceable to the original manufacturer and built to MS27641 specifications.
The MS27641‑6, also known as KP6A, is an intermediate‑duty airframe ball bearing designed for flight‑control linkages, landing‑gear mechanisms, and other aircraft systems requiring a compact bearing with tight tolerances. This single‑row, radial contact bearing features a 3/8" inner diameter and 7/8" outer diameter, with inner and outer ring widths of 0.313" and 0.250" respectively. Dual PTFE contact seals help keep grease in and contaminants out, while heat‑treated E52100 steel rings and balls deliver consistent performance. Factory grease fill to MIL‑G‑81322 supports extended service life. A cadmium finish and stainless retainer enhance corrosion resistance. Each unit is new and fully traceable to the original manufacturer, providing confidence for maintenance shops and aircraft owners seeking an OEM‑spec replacement.

Solid bond, works easily, allows plenty of work time and cures overnight.
While shipping was slow, typical USPS, not Pilots HQs fault, I was happy to get the product in a somewhat reasonable time frame. Product works great.
We use these pillow cases in our office. They have a clean fit and are very easy to change between patients.
Simple purchase, a book. Simple or not, ordered, paid, was informed the process was moving, delivered on schedule. All as one would hope. 🤙
