5GN150K Oriental Motor Parallel Shaft Gearhead, 150:1, 90 mm Frame, Very Low Speed Output
The 5GN150K from Oriental Motor is a GN-type parallel shaft gearhead with a 150:1 ratio, one of the highest reductions in the 5GN range. It fits 90 mm (3.54 in.) square frame motors with a GN-type pinion shaft and brings the output down to about 12 r/min at 60 Hz (10 r/min at 50 Hz). That very slow, steady rotation suits display turntables, timing and dosing mechanisms, slow agitators and other drives where precise low speed matters most. The 12 mm metric output shaft takes standard couplings, sprockets and pulleys.
5GN150K Specifications (Oriental Motor)
| Specification | Value |
|---|---|
| Product type | Parallel shaft gearhead |
| Series | GN type |
| Gear ratio | 150:1 |
| Frame size | 90 mm sq. (3.54 in. sq.) |
| Output shaft | 12 mm, metric |
| Output speed (calculated) | 12 r/min at 60 Hz / 10 r/min at 50 Hz* |
| Supply | Sold separately from the motor |
*Synchronous motor speed (1800 r/min at 60 Hz, 1500 r/min at 50 Hz) divided by the gear ratio. According to Oriental Motor, the actual speed is 2–20% lower depending on the load.
Why Choose the 5GN150K
- Very high reduction: around 12 r/min at 60 Hz for slow, controlled motion
- Simple speed reduction: no electronic speed controller needed for a fixed low speed
- Compact parallel shaft design: mounts in line on the 90 mm motor
- Modular gearing: swap the ratio later without changing the motor
Typical Applications
- Display and rotary turntables
- Dosing, timing and metering mechanisms
- Slow-speed agitators and mixers
- Low-speed indexing and positioning drives
