RMI Traction Drive Design• Two-Ball Bearing Design• Replaces Sliding Friction with Rolling Friction• Units operate on a 10° Angle Between Input and Output Shafts

2

What Makes RMI Different• New Technology • Ratios Ranging from 1:1.5-1:4• Significant Reduction in Manufacturing Costs vs.

Traditional Gears• Minimal Moving Parts• Only Rolling Friction• Reduced Heat, Noise, and Vibration• Built in One-Way Slip Clutch - No back driving of

Components• True High Efficiency at any Load/Speed
