• 9 exact ratios from 5.2:1 to 90:1
• 3 levels of backlash precision:
  
  Expert < 1 arc minute
  Medium < 5 arc minutes
  Basic < 10 arc minutes

Features & Benefits:

• Low Backlash - Three levels of backlash from 10 arc minutes to less than 1 arc minute assures the proper repeatability for your application.

• Multiple Output Options - Available in single or double output shafts, hollow bore with keyway, or hollow bore with shrink disc for maximum design versatility.

• Universal Motor Mounting - Provided with an adapter for virtually all servo motors and a torsionally rigid flexible coupling for optimum motor shaft alignment.

• Optimized Gearing - Hardened and ground worms and bronze alloy wheels provide high torque, smooth operation, and superior shock absorption.

• Higher Radial Load Capacity - Oversized taper roller bearings accommodate high radial forces.

• Lower Noise - Precision worm gearing provides noise levels below 55dB.

• Aluminum Alloy Housings - A hardened aliminum-magnesium alloy housing results in lower weight and higher torsional rigidity.

• Constant Worm Bearing Preload - A unique 3 bearing arrangement maintains proper worm bearing preload over all allowable temperature ranges.

• Gearhead Mounting Options - Tapped holes, through holes, and centering flanges maximizes gearhead integration.
