Screw Jack
Ball Small Jack
Outline
Extremely compact, lightweight, and easy-to-use jacks, delivering high performance similar to standard ball screw jacks
Features
- – Basic capacity: 4 kN
- – The lightest weight possible is achieved, while securing sufficient strength.
- – The housing is compact and designed to allow either its upper or lower surface to be attached to your device.
- – High-efficiency and high-speed operation is enabled by using rolling friction.
- – We can also manufacture a jack with an anti-rotation mechanism that prevents its screw shaft from co-rotating.
- – Wide-ranging options are available, including dustproof bellows to protect the screw shaft, limit switch for control, and RC encoder.
- – The jack does not have a self-locking function. It is required to install a brake.
