Rectangular Flat Air Bearings LSAP075150 / 610-22082

Number of Units:

Frictionless linear or rotary motion in a plane can be achieved by using this small air bearing. Its rectangular shape can be placed efficiently within certain linear guideway applications. Despite its small surface area, this air bearing has a stiffness of over 160,000 lbs/inch and carries 30 pounds of load. As with all LSA series bearings, this air bearing has equal performance at zero, low and high speeds.
