Key Technical Specifications
| Item | Parameters | Description |
|---|---|---|
| Product Series | PLM Round-Body Square-Flange Helical Gearbox | Precision Planetary Gearbox |
| Specifications / Frame Size | 140 | Model Specifications |
| Gear Ratio | L1: 3/4/5/7/8/10; L2: 12/15/16/20/25/28/30/35/40/50/70/100 | Reference configurations: PLM140-L1-22-110-145.jpg; PLM140-L2-35-114.3-200.jpg. Values below apply to these drawings; other motor interfaces and custom outputs require separate confirmation. L1 drawing has a conflicting flange PCD annotation (145 versus 200 mm); confirm interface dimensions before ordering. |
| Rated Output Torque | L1: 360–480 Nm; L2: 360–480 Nm | Ratio: torque (Nm). L1 — 3/10:360; 4/5/7:480; 8:440. L2 — 12/15/30/100:360; 16/20/25/28/35/40/50/70:480. |
| Maximum Torque | 1.5 × rated output torque | Drawing-listed maximum; not a continuous-duty rating. Confirm allowable duration and duty cycle. |
| Backlash | L1: ≤3 arcmin; L2: ≤5 arcmin | Reference configurations only; accuracy may differ for other interfaces. |
| Maximum Input Speed | 6000 rpm | Maximum input speed; confirm duty cycle for the selected ratio. |
| Rated Speed | 3000 rpm (input) | Rated input speed, not output speed. |
| Efficiency | L1: 95%; L2: 90% | Reference configurations only; other interfaces may specify different efficiency. The L2-19-110-145 drawing instead lists 95%, ≤7 arcmin backlash and 16 kg. |
| Operating Temperature | -10 to +90 °C | Drawing-listed range for the reference configurations. |
| Maximum Axial Force | 4700 N | Drawing-listed maximum; confirm combined loads and load position. |
| Maximum Radial Force | 9400 N | Drawing-listed maximum; confirm combined loads and load position. |
| Weight | L1: 16 kg; L2: 21.5 kg | Drawing tolerance ±3%; motor interface and custom output change weight. |
| IP Rating | IP65 | Reference configurations only. |
| Service Life | 20,000 h | Drawing-listed value; actual life depends on load, speed, duty cycle and operating conditions. |

Match the model, reduction stage and motor interface to the drawing. Custom input or output dimensions require a separate set of files.
Selection FAQ
PLM140 Can I Order by Model Number Alone?
First confirm the gear ratio, Load, Output Speed, Mounting orientation and motor interface. The same frame size may have different interfaces and configurations.
Drawings and 3D How to Confirm Models?
Find resources on this page or in the Download Center, Confirm the final version against the motor interface and machine mounting dimensions.
What If My Specifications Are Incomplete?
Provide the Motor Model, Load, Target Speed, Required Torque, Cycle Time & Installation Space, Our engineers can help confirm the requirements.
