1. One way clutch @ Made of tungsten carbide steel on the contacting surface to keep rigidity, precision and durability. @ The gear is hardened to HRC60° And ground to the best transmission accuracy. 2. Roller @ High feed accuracy at exact positioning with hollow roller of less weight, and lower inertia. @ Hard chrome plated heat treated to HR60° For the best rigidity. 3. Disk Brake @ Apply the best brake lining to have accuracy, durability, and rigidity. 4. The Anti-reversing Device (1) The structure is same as the one way clutch. It can precisely control the lower roller which will not reverseeven for long time ysed as it is high in stability and precision. (2) The brake will not out of control by the splashed waste oil when it is punching such such cause the lower roller to reverse, and transfer distance unprecise. (3) It will not cause high heat. (4) Superhard alloy and rolling post have been used. They are not easy to wear out. (5) The acting form of the rolling posts is by circular movement, not like the four guided posts in straight line moving, so it will not stuck. (6) As less friction it will acurred, so the torsion it need will correspondingly reduced, And the transfer structure will not easy wear out. (7) Speed can be reached to 30m/min if the anti-reversing device is fitted. In general it is 20m/min. Efficiency has been increase about 50%. (8) Its special structure has been increased its using life.
