Description Ordering Information Specifications and Drawings
 
LIMING: Planetary Reducer PB90-1/5-19+7MP90A-70-A W/O MOTOR
This is a high-precision, industrial planetary gearbox manufactured by LI MING Machinery (LIMING). This specific model is a right-angle or inline speed reducer designed to increase torque and lower the rotational speed of electric servo motors in automation and CNC applications.
Key Component Breakdown:
PB90: The PB Series frame size (90mm), engineered with high-precision helical gears for smooth, quiet, and high-efficiency operation.
1/5: The reduction ratio, which is 5:1 (meaning the output shaft rotates once for every five rotations of the motor).
19: The input bore or shaft diameter (19mm), which dictates which motor can be physically coupled to the gearbox.
+7MP90A-70-A: Designates specific custom flange, coupling, or adapter codes used to mount the servo motor accurately without backlash.
Important Operational Details
Efficiency: Typically exceeds 97% efficiency for single-stage models.
Backlash: Designed for minimal backlash to ensure high positional accuracy in robotics and CNC machinery.
Lubrication: Pre-lubricated with high-grade synthetic grease, but requires proper maintenance if subjected to heavy duty cycles.
Noise Rating: Engineered to keep noise strictly under 70 dB during operation.
