OAV Air Bearing Linear Slides are high precision and accurate air slide assemblies. Our Bearings provide you with the confidence of integrated bearing motion systems and dynamic response that is much better than conventional rolling bearings.

​OAV Air Bearing Linear Slide assemblies combine an accurate guide surface with an air slide ready-fit for installation. This provides the user with the convenience of integrated guide and bearing systems. 

The Outer Spin Rotary Air Bearing provides the ability to spin outer rings with an incredible accuracy of TIR± 1 millionths inches (.025 microns) while maintaining zero friction and contact, zero maintenance, no generation of thermal energy at high speeds, and a limitless operating life. This ultra-precise, hard-installable innovation is here to replace conventional bearings with unmatched improvements and efficiency. OAV Air Bearings offers products that have significantly higher levels of stiffness with superb geometric performance.

The OAV External Spin Rotary Air Bearing preloads both the horizontal and vertical surface with an opposing thin film of pressure, maintaining the perfect gap and optimal levels of tolerance.

The table below lists the three different X-Spin Roller Air Bearings available: 

Part NUMBER	INSIDE DIA.	OUTSIDE DIA.	BEARING WIDTH	Radial load	Thrust load	Datasheet
OAVRL13MX	13mm	44.5mm	22mm	57.8N	133.5N
OAVRL40MX	40mm	100mm	36mm	178.4N	320.3N
OAVRL75MX	75mm	140mm	51mm	578.3N	1245.5N

The OAV Modular Air Bearing design subdivides motion systems into smaller installable parts. They can be independently installed and then used in different systems and shapes. OAV Modular Air Bearings make use of industry standards for interfaces. 

​OAV Modular Air Bearings offer many benefits such as reduction in cost, shorter installation time, flexibility in design, augmentation, and exclusion. It is a complete offering of air bearings produced with the design for easy retrofitting into existing applications or designing into new applications for ultimate accuracy positioning.

​OAV Air Bearings generate evenly distributed gas films between surface and the substrate. Because of low gas viscosity and friction losses by viscous shearing, mechanical contact is avoided. Our modular air bearings are manufactured from aircraft quality lightweight material. It is ultra-precise with exceptional linear straightness and flatness. Vibration and maintenance-free, ready to install.

The OAV Thrust Air Bearing is a breakthrough innovation in air bearing technology. For the first time, an air bearing is available that fully integrates and works on a three-way frictionless surface. The OAV Thrust Air Bearing configurations run on standard sized shafting for fixed, linear motion while maximizing rotational motion with ultra precision and zero friction using aerospace quality aluminum.

​OAV Air Bearings have higher stiffness and excellent geometric performance. The OAV Thrust Air Bearing preloads both the horizontal and vertical surfaces with opposing thin films of pressure. This maintains the perfect gap for ultimate tolerance, and the surface design of the bearing equally distributes the air and pre-loads it over the entire surface area. The result is outstanding stiffness with maximized performance.
