Linispeed Jack
- This is Ball screw lifting unit that can make the most of the performance of the servo motor.
- Linispeed Jack achieves a maximum operating speed of 200 mm/s and a maximum Percentage duty cycle of 100% ED, helping to improve the productivity of your equipment.
Even when operating at higher speeds, the jack is smaller than conventional jacks, and the newly developed structure allows for a low profile, contributing to more compact equipment.
Features
-
・Super high speed
Conventional jacks had a maximum screw shaft speed of 120 mm/s, and the faster the speed, the larger the jack needed to be.
Linispeed Jack achieves a "constant thrust" that can transport heavy loads at high speeds of 200 mm/s without increasing the size.
-
・Low profile and compact
Linispeed Jack is even more compact by placing the ball nut inside the worm wheel.
The dead space that previously existed due to the height of the nut is eliminated, allowing for a lower floor. This reduces the overall height of the device and creates more room for lifting.
-
- Traveling nut specification for pit-less design
Pitless operation is now possible even in environments where pits were previously required.
Basic form
A pit is required in the floor
Traveling nut specifications
Can be placed directly on the floor, no pit required
-
・High frequency operation
Linispeed Jack achieve a maximum allowable Percentage duty cycle of 100% ED, enabling continuous operation and greatly contributing to increased productivity of equipment.
Furthermore, Ball screw 's expected travel distance is achieved in line with high-frequency operation.
-
・Comprehensive ease of use
Linispeed Jack maintains ease of installation and interlocking operation, while enabling high-speed, high-frequency operation and a low profile.
Furthermore, high-speed input allows the motor and coupling to be made compact.

・The position of the pressure vent and drain plug varies depending on the mounting style. Mounting styles other than screw facing up or down are special orders.
- Bellows are available as special models. Please contact us as consideration is required depending on the screw shaft speed. The bellows protect the screw in a dusty environment. They do not prevent water from entering from the outside.
*Please limit the screw compression load/screw tensile load to 50% of the allowable thrust.
*When a screw compression load is applied to TS, BS, PS, or HS, limit the thrust to 50% of the allowable thrust.
*When a tensile load is applied to the screw with TC, BC, PC, or HC, limit the thrust to 50% of the allowable thrust.
