5GN75K Oriental Motor Parallel Shaft Gearhead, 75:1 High Ratio, 90 mm Frame
The 5GN75K from Oriental Motor is a high-ratio GN-type parallel shaft gearhead (75:1) for 90 mm (3.54 in.) square frame motors with a GN-type pinion shaft. The high reduction brings the output down to about 24 r/min at 60 Hz (20 r/min at 50 Hz). That makes it suited to slow, controlled motion such as indexing tables, turntables, mixers and slow-moving conveyors, where low speed and high output torque matter more than throughput. Power is delivered through a 12 mm metric output shaft, and the gearhead mounts directly onto the motor flange.
5GN75K Specifications (Oriental Motor)
| Specification | Value |
|---|---|
| Product type | Parallel shaft gearhead |
| Series | GN type |
| Gear ratio | 75:1 |
| Frame size | 90 mm sq. (3.54 in. sq.) |
| Output shaft | 12 mm, metric |
| Output speed (calculated) | 24 r/min at 60 Hz / 20 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.
Advantages of a High-Ratio Gearhead
- Slow, steady output: about 24 r/min at 60 Hz for controlled, low-speed motion
- High torque multiplication: suited to heavier loads at low speed
- Direct flange mounting: compact in-line assembly with a 90 mm GN pinion motor
- Modular: change ratio or replace the gearhead without replacing the motor
Typical Applications
- Indexing tables and turntables
- Slow conveyors and accumulation tables
- Mixers, stirrers and agitators
- Doors, shutters and positioning mechanisms
