The tapered bearing is one of the most commonly used forms of roller bearings in the industry. OAV is proud to be the first to introduce the Tapered Roller Air Bearing. Consisting of two main components – the inner assembly, and the outer-cage, the two components are typically mounted in opposing pairs on a shaft. Air supply is sent through the shaft with a cross-hole or inlet from the outer-cage. The OAV Tapered Roller Air Bearing has standard sizes available up to a 75 mm ID outer-cage spin or inner-race spin with options.
