We have benchmarked competitors and found some with DIN ratings as high as 12! (higher numbers equal less uniform gear profiles). International DIN ratings relate to the uniformity of the surface and overall concentricity with our DIN rating of 6 being considered outstanding.
In addition, our superior DIN rating enables tighter gear backlash by design, basically there is no need for us to build in excessive backlash as compensation.
Our Swiss engineers designed the pitch, angle and profile of HGT Precision gears for ultimate efficiency and strength resulting in a gearbox that runs cooler with very low noise levels relative to some other brands. We use constant mesh dog engagement for bullet quick changes as fast as 38 milli-seconds.
All gears are heat treated inhouse to ensure strength and longevity.
