38 mm x 118 mm Epoxy Bonded Air Bearing. Manufactured with aerospace quality material. Epoxy bonded air bearings utilize a thin layer of epoxy to bond the surface of the air bearing to the supporting structure, offering higher precision, less friction, and longer life. The thin layer of epoxy serves as a cushion, allowing for higher stiffness, greater accuracy and near frictionless movement while maintaining a low-profile. Additionally, epoxy bonded air bearings are able to withstand wide temperature ranges, vibrations, shock, and other harsh environmental conditions.
