Product Description

Cycloid Gear Speed Reducer

Taiwan C. Varitron Cycloidal Speed Reducer delivers the features today’s industry needs. High reduction ratios, without sacrificing efficiency. Compact designs, without requiring special motors. Exceptional shock load capacity, without having to oversize. Greater overhung load capacities, without using expensive special components. A precision backlash option, without resorting to special gearing. All of this, while requiring minimal maintenance.

• Single stage reduction ratios up to 87:1 saves space

• Rolling motion minimizes friction and wear, reducing heat,resulting in a 95% efficiency rating per stage

500% shock load capability as there are only compressive forcesrather than shear forces on the tooth

• Low speed of cycloidal wheel results in minimal reflected inertia,less wear, and extremely long service life

• Due to the large overall “tooth / pin” contact area, select aReducer using smaller mechanical service factors

  • Horizontal,vertical, double shaft, motor mount and others
  • W/AC,DC, Servo Motor, Brake, Hydraulic, Air Explosion Motor
  • Motor provided is 100% Taiwan made with CE & ISO cert.
  • Ideal for stop/start and reversing operation
  • Brakes can be added
  • Cycloidal Reducers’ bearings uses KOYO, NTN, SKF, NSK
  • Flange diamentions or shaft can be coustomise.
  • Ideal reducers,gearbox to meet yourspeed transmission needs.
  • Same foot mounting as Sumitomo
