• Bottom and Workbench Contact, except the four screw holes, the center ring directly below the bearing also contacts the worktable.
• Our pinion module is larger than other brands, other brand modulus is 0.8-0.9, we are 1.25, so at high deceleration ratio of 18, our gear strength is better.
• There are steel rings at the bottom, and the load is borne by steel parts, in case the bearing presses the aluminium structure to deform clearance.
• An integrated design of gear and cross roller bearings is under developing, it can improve rotation accuracy and stability.
• Electroless nickel plating on working face, heat-treat, to prevent rusting and scratching.
