OAV Roller air bearings

Air Bearing Rollers for Frictionless Motion Replacement

OAV Roller Air Bearings are designed as a direct replacement for conventional rolling elements, delivering frictionless motion with zero mechanical contact. By using advanced porous graphite air film technology, these rollers eliminate wear, reduce heat generation, and provide ultra-smooth motion even at high speeds.

​

Unlike traditional roller bearings, OAV air bearing rollers maintain a consistent, pressurized air gap between surfaces—removing friction, vibration, and performance degradation over time. This results in significantly longer service life, improved system efficiency, and maintenance-free operation in demanding environments.

​

Engineered for precision and durability, OAV roller air bearings provide high stiffness, excellent load distribution, and stable motion across both horizontal and vertical axes. Their non-contact design ensures consistent performance while minimizing runout, making them ideal for applications requiring smooth, reliable, and repeatable motion.
