DBR Series Helical Precision Planetary Gearbox

Helical gear design ensures quiet operation. Backlash ≤5 arcmin for precise positioning. Large-size, double-support bearing boosts rigidity and torque. Efficiency: 1-stage ≥95%, 2-stage ≥92%. Low grease wear, lifetime lubrication. IP65 sealing prevents leakage. Any orientation. Fits all servo motors.

Features

Low Noise: Helical gear design achieves smooth and quiet reducer operation.

High Precision: Backlash ≤5 arcmin enables accurate positioning.

High Rigidity & High Torque: The output shaft uses a large-size, large-span double-support bearing design, significantly improving rigidity and torque.

High Efficiency: Up to 95% or more for 1-stage, and 92% or more for 2-stage.

Maintenance-Free: Low grease wear allows for lifetime lubrication.

Excellent Sealing: High-viscosity grease resists separation, and IP65 protection rating ensures no grease leakage.

Unrestrained Installation: Can be installed in any orientation.

Wide Applicability: Compatible with all types of servo motors.
