  • + Single row, ball, external self aligning.
  • + Equipped with Teflon seals.
  • + Exposed surfaces except bore, cap, and seals are cadmium plated.
  • + Prelubricated.
  • + Series is internally identical to the KP-B series. Self-alignment is provided by an external self-aligning ring whose internal sphericallyground surface is accurately matched to the external sphericallyground surface of the outer ring. These bearings are designed to compensate for initial misalignment.

Standard 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. 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.

  • Core Values

    We have one of the largest bearing inventories in the U.S. We stock other manufacturer's bearings. We distribute bearings for extreme high temperature. We will ship all bearing orders the same day for less than any other advertised price.

  • Certifications
