Now LIMON hollow rotary actuators are sized in 60,85,135,200. The surface is through high and middle
heat treatment which the grinding precision can be
ISO6 and surface hardness HRC 65.Also the repetitive accuracy is ±15arc-sec, and
concentricity&flatness ±0.05 mm.
These data above is under the strict control by LIMON to show its quality, now the hollow rotary
actuator is applied in different industries especially
in the 3C industry like the grinding machine of mobile phone shells also highly matched with the
linear module for some applications.
•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.
Now the hollow rotary actuator is applied in different industries especially in the 3C industry like
the grinding machine of mobile phone shells, also
visual testing equipment,Laser equipment industry, Semi-conduct equipment industry,etc.
