Uncompromising Quality

PACAMOR KUBAR is a trusted name in high precision OEM and replacement ball bearings for commercial, private and military guidance and navigation systems.  Whether the device is used in an aircraft, water way patrol vehicle, sport craft or is launched in an elite ballistic missile, PACAMOR KUBAR bearings offer uncompromising reliability, delivered when you need them.

Bearing Technology

PACAMOR KUBAR offers a range of retainer designs and materials including, but not limited to, stainless steel Crown, two-piece Ribbon, Torlon  (polyamide-imide), and Phenolic. 

All instrument bearings for guidance and navigation systems are manufactured from 440C stainless steel, the preferred choice for all our high precision, miniature and instrument bearings.  Its corrosion  resistance is preferred under adverse environmental conditions.  Its highly finished, honed surface provides a long lasting structure for the 440C or Silicon Nitride (ceramic) balls, which allow the bearing to rotate smoothly at a variety of oscillating or rotating speeds.

PACAMOR KUBAR miniature and instrument bearings are produced to meet ABEC tolerances (as defined by the American Bearing Manufacturers' Association).      

Bearing Lubrication

Bearings are lubricated with temperature and moisture resistant oils and greases.  Optional shields or seals prevent the introduction of contamination.

Pacamor Kubar Bearings is a domestic manufacturer of high precision miniature and instrument bearings and offers over 40 years of expertise in radial ball bearings. Located in Troy, NY, Pacamor Kubar Bearings is one of the last American owned and operated miniature and instrument ball bearing manufacturers.
