LEESUN aluminum alloy guide roller selection of high quality aluminum alloy material extrusion molding, with the strengthening of the structure, high strength, the whole shaft computer balance correction processing, so that the balance of the amount of up to 2G, and the use of imported processing equipment and special tools, measuring tools, so that the surface roughness of 1.6 and 0.8, with the axis of 0.02mm. Shaft end with special process, with the imported bearing, in the high-speed operation, can be easily operated. Roller surface style can choose: smooth, sandblasting, roll flower and Teflon Teflon processing, the surface can be special hardening treatment, the roller surface hardness of hv300 or hv700, has good resistance to scratching, abrasion resistance, prolong the service life.
