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.
