Nippon Gear Co.
Nippon Gear Smoothy Screw Jack
Manufacturer: Nippon Gear Co., Ltd.
Features
- Capacity: 2kN/5kN
- The lightest weight possible is achieved, while securing sufficient strength.
- The housing is compact and space-efficient; and its shape and mounting holes are designed to allow either its upper or lower surface to be attached to your device.
- Conserves space as steel spheres and return tubes are not required.
- We can also manufacture a jack with anti-rotation mechanism which prevents its lifting screw from drag turning.
- Wide-ranging options are available, including dustproof bellows to protect the lifting screw, limit switch for control, and RC encoder.
- Maintenance-free design (disassembly of components inside of the housing is not allowed); however, please apply grease to the lifting screw on a regular basis.
- The jack does not have a self-locking function, so it is required to install a brake.
- A smoothy screw, consisting of a self-lubricating nut and stainless screw shaft is also available as a stand-alone product.
