Air Bearings have been emerging as a very important element to precision technology. Many questions and concerns arise when determining how to implement air bearings. In some cases there is a tight budget in which it will be too costly to replace the shaft or too costly to modify the bore diameter of the housing. OAV Air Bearing has a solution to all of the above. The innovative design includes an all-in-one package with the core air bearing and face collars in one product. Therefore, there is no need for careful alignment with the face collars since the air bearing is already pre-adjusted and tuned for maximum performance. OAV Air Bearing brings Roller Air Bearings into the market. This is the most convenient of all rotary air bearings. Perfect for spindle applications or any application which requires smooth and precise rotation.
