Key Advantages of ZCDR Series
90-Degree Transmission
Right angle output direction helps machine builders save installation space and simplify compact servo drive layouts.
High Torque Output
Planetary gear transmission supports stable torque delivery for indexing, feeding, positioning, and heavy-duty motion tasks.
Servo Motor Matching
Multiple frame sizes and ratios support different servo motor interfaces, speed requirements, and automation load conditions.
Industrial Reliability
Designed for continuous equipment operation, compact machinery, robotic systems, and demanding production environments.
Ordering Code Example
Example ordering code: ZCDR-90-5-19-70-90-M6. Move your mouse over each segment to see the meaning. Final motor interface dimensions should be confirmed according to the selected servo motor and installation requirements.
Series and Frame Size
ZCDR identifies the right angle planetary gearbox series. The frame size should be selected according to torque, motor power, installation space, and load condition.
Ratio Selection
Lower ratios are suitable for higher speed output. Higher ratios help increase torque output and improve motion stability.
Motor Interface
Motor shaft diameter, pilot diameter, mounting hole pitch, and screw size must match the servo motor drawing.
Selection Note
Before ordering, confirm torque, speed, backlash, load type, duty cycle, radial load, axial load, and installation direction.
Motor Interface and Installation Dimensions
Before ordering a ZCDR right angle planetary gearbox, please confirm the servo motor interface, shaft diameter, pilot diameter, mounting hole pitch, and mounting screw size. These values affect motor matching, flange alignment, transmission stability, and installation accuracy.
Motor Shaft Diameter
Confirm the motor shaft size before selecting the gearbox input bore.
Motor Pilot Diameter
The pilot diameter helps align the servo motor and gearbox input side accurately.
Mounting Hole Pitch
Check the motor mounting hole distance to match the adapter flange.
Mounting Screw Size
Select the correct screw size to ensure stable motor installation.
Reducer Operating Condition Selection Table
