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.
