Nippon Gear Co.
Nippon Gear High Speed Jack
Manufacturer: Nippon Gear Co., Ltd.
Features
- Capacity: 5kN~50kN
- Lifting screw speed: Max 20m/min)
- Compared to the Ball Screw jack it is 5 times faster.
- Duty cycle: Max 70% ED
- Has 5 times duty cycle compared to the conventional product
- Input rotation speed: Max 2000~3000min-1
- Can be used for wide-ranging operations by utilizing a servomotor.
- This type of jack does not have a self-locking function, so it is required to install a brake.
