PLR Series Spur Gear Precision Planetary Gearbox

This precision spur planetary reducer features helical gearing for quiet operation, backlash ≤8 arcmin, and a double-support bearing design for high rigidity and torque. With up to 95% efficiency, IP65 sealing, lifetime lubrication, flexible mounting, and universal servo motor compatibility, it delivers reliable, high-performance motion control.

Features

Low Noise: Helical gear design ensures smooth and quiet operation.
High Precision: Backlash of 8 arcmin or less enables accurate positioning.
High Rigidity & High Torque: The output shaft features a large-size, large-span double-support bearing design, which significantly improves rigidity and torque capacity.
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 lubricating grease resists separation, and the IP65 protection class ensures zero grease leakage.
Flexible Installation: Can be installed in any orientation.
Wide Applicability: Compatible with all types of servo motors.
