Published configuration codes use the TJX24RA family. Confirm the full configuration code against the selected drawing when ordering this 24JX370 platform.
Compare reduction ratio, output speed, load torque and gearbox length as one configuration.
Performance and dimensions are subject to the selected winding, reduction ratio where applicable, drawing and agreed test conditions. Please confirm the current configuration with Hongyang before ordering.
Dimensions, curves and interfaces.
mechanical drawing; gearbox length L varies with stage
The selected drawing controls shaft, mounting and tolerance details. Any lettered dimensions without a value are specified for the chosen build.
Fit the motor to your assembly.
24 mm planetary gearbox with 20 ratio configurations and in-line output. Use an existing configuration as the starting point, then review the interfaces that connect it to your equipment.
Output speed / load torque selection
Review continuous and peak torque together with output speed.
Output shaft and mounting review
Define shaft engagement, external loading and mounting position.
Winding and supply selection
Include the supply, operating cycle and any required feedback or holding behavior.
This published 24JX370 configuration is not available with an encoder. Discuss feedback requirements before selecting an alternative series.
Evaluate the motor in the real mechanism.
Loaded output
Select output torque and speed together; allow for starting and peak loads.
Mechanical fit
Check shaft loading, support, orientation and mounting envelope.
Duty and control
Define run time, reversing cycles and the required control behavior.
Length by gear stage
The gearbox length changes with the reduction stage. Use the length from the selected row and drawing.
Create a clear approval baseline.
Technical inquiry
Send this series name, the full variant if selected, the installation drawing and required working point.
Sample evaluation
Check fit and performance in your equipment. Record the supply, load, duty and test method.
Production approval
Agree the drawing revision, model code, acceptance requirements and order quantity before release.
