PGR-series use Spiral bevel gear and precision grinding gears, smooth teeth surface, and high accuracy. High Input speed. High strength and lightweight aluminum casing.

1. High Positioning Accuracy
Precision grinding gears, smooth teeth surface, and high accuracy.
Single-piece structured ring gear with housing, alloy steel, high reliability.

2. High torsional Rigidity
Use superior taper roller bearing can bear much more axial and radial loads, high torque, and widespread application.


3. Low Backlash
Precision process and strict quality control:
Micro backlash one stage ≦2 arcmin , two stage ≦4 arcmin
Reduced backlash one stage≦4 arcmin , two stage ≦ 6 arcmin.
Standard backlash one stage≦6 arcmin , two stage ≦ 8 arcmin.

4. High Efficiency
One-stage 97%, Two-stage 94%
