  • + Single row, ball, self-aligning.
  • + Equipped with bonded Teflon seals.
  • + Exposed surfaces except bore, cap, and seals are cadmium
  • + Prelubricated.

  • (1) These bearings are self-aligning for 10° in either direction except MKSP4A, MKSP5A and MKSP6A

    Note: These bearings should not be used as track rollers, cam follower rolls, and the like.which are self-aligning for 8° in either direction.

     

Precision Series CONTROL BEARINGS category

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.
