  • + Single row, ball, deep groove.
  • + Rings and balls are made of 44OC stainless steel (not cadmium plated).
  • + Equipped with Teflon seals.
  • + Prelubricated. (See Table 1, page 111 for options.).
  • + Bores and outside diameters of this series are the same as forcorresponding sizes of the KP-A Series, but rings are widerfor retainers and seals, and offsets between inner and outer ring facesare greater, providing increased bracket clearance at mounting

aerospace bearings

Ball Bearings

We can help design/manufacture any bearing. We stock other manufacturers: Barden, Fafrir, MPB, SKF, Kaydon, FAG, ND, KOYO, NSK, RMB, KBC, SMT, GMN, etc.

Cylindrical Roller Bearings

Cylindrical roller bearings for aerospace applications are capable of handling high radial loads and a wide range of application speeds.

Tapered Roller Bearings

Tapered roller bearings can withstand high accelerations and de-accelerations, heavy loads and a variety of temperature and environmental conditions.

Spherical Roller Bearings

Spherical roller bearings are the preferred choice when operating conditions include heavy loads and difficulties with housing alignment or shaft deflection.

Resources

  • our mission

    Our engineers are the best in the industry. We work directly with our OEMs and Bearing Distributors. Our engineers can help you with bearing, shaft and housing tolerances as well as semiconductor applications, cryogenic applications, extreme hostile environments, and extreme delta T temperatures environments.
