MS27649 AW-AK Series
MS27649 AW-AK Series
The AW-AK Series Radial, Stainless Steel Airframe Control Ball Bearings are designed according to MS27649 and SAE-AS7949 standards. These are single row, deep groove ball bearings made from CRES 440C stainless steel, which are not cadmium plated. They feature PTFE seals and CRES sealcaps and are prelubricated for life. The bores and outside diameters match those of the KP-A Series, but the rings are wider to accommodate retainers and seals, providing increased bracket clearance at mounting.
To order, specify the bearing number and factory specification as indicated in Table 1 on page 8. For example, AW3AK FS464.
The document provides detailed measurements for various models in both inches and millimeters, including bore diameter, outside diameter, and width. It also lists the approximate weight in pounds and kilograms, as well as the radial and thrust limit load ratings in pounds-force (lbf) and newtons (N).
Some models, such as AW10AK, AW12AK, AW16AK, and AW20AK, are not currently in production and will be manufactured as demand justifies tooling. Availability should be checked before ordering.
