ABR042 / ABR060 / ABR090 / ABR115 / ABR142 / ABR180 / ABR220

Features
  1. Higher output torque rating by using spiral bevel gear design. 30% more than straight bevel gear.
  2. Allows input speeds up to 8 times than with straight bevel gearing.
  3. Improved load sharing through precision tooth design and longer service life.
  4. Ground gears verified with sophisticated software, ensures smooth, quiet operation with reduced backlash(<=2arcmin)
  5. High tensile low weight single piece aluminum alloy housing for highest stiffness.
  6. Maintenance free lifetime lubrication.
  7. Patented sealing design for high speed and continuous running.
  8. High efficiency up to 95%. Low noise level down to 61 dB.
  9. Most ratios available from 3~200.
