PowerTRUE™ 90 Technology

Right angle gear meshes are typically limited to ratios from 1:1 to 3:1 when using standard bevel gears. Compared to these designs, the PowerTRUE™ 90 gear increases the ratio range to 5:1. The key to higher torque density is a unique tooth design, created by complex machining made practical with advanced CNC equipment and software. In the design, multiple teeth in the face gear simultaneously mesh with a standard involute pinion. The continuous tooth engagement yields a high contact ratio between the gear and the pinion, boosting torques to new levels and efficiency to 98%.

  • Lower backlash accomplished through single axis mesh adjustment
  • A compact right angle design utilizing a high-tech face gear
  • Whisper quiet operation due to high contact ratio
  • Mesh ratios from 1:1 to 5:1
  • 98% efficiency
