Axis applications, from a professional point of view of the centerline axis of the beam, or a symmetry axis of the optical system. Astigmatic axis optical axis can be divided into primary and secondary optical axis of the optical axis. The other angles can be divided into solid shaft, hollow shaft, stainless steel shaft and alternative machining axes. Basic understanding of the optical axis of classification, and now we look at the optical axis applications. Let me talk about the optical axis of the solid shaft bearings, generally we used more for industrial robots, or as a professional measuring instruments, medical equipment, precision machine tools, aircraft shafts, pneumatic rams moving parts. Secondly hollow shaft, hollow shaft itself as a lighter, but also can reduce the weight of the equipment, to simplify the structure of the advantages of joint bearing manufacturers can measure the wire, compressed air inside the hollow shaft can be added to the lubricating oil and hydraulic oil. Custom-made stainless steel shaft bearing joints, generally used for corrosive environments chemicals, water and other substances, as part of the measurement. Finally, through a special machine axis, we have hard chrome plating completed after heat treatment is generally used on all types of automation equipment. Metal linear bearings conservation: lubrication and friction: Internal linear bearings injected anti-corrosion oil, if using grease lubrication, first with kerosene or organic solvents remove anti-corrosion oil supply bearings, then add the dried grease. (Recommended for lithium soap grease sticky tags N0.2 of.) If oil lubrication, do not remove anti-corrosion oil, according to the temperature change can be selected ISO viscosity grade oil VG15-100 shaft lubrication oil supply line from to no, or from the outside of the hole to the oil bearing housing. Since the ring will scrape oil, oil lubrication NA nonporous with a ring bearing.
