Outline
This type is capable of two-way conversion: it can directly convert rotary motion into linear motion, or linear motion into rotary motion.
Features
-
Capacity: 2 kN / 4 kN
-
Allows high-speed linear motion even when the input shaft is rotating at low speed.
-
Delivers excellent mechanical efficiency with less power loss.
-
Equipped with two mounting surfaces: one parallel to the rack’s motion, and another at a right angle. Users can choose whichever surface is more convenient.
-
Offers 3 types of shaft end fittings, along with a wide range of options such as dustproof bellows to protect the rack shaft, limit switch for control, and RC encoder.
-
This type of jack does not have a self-locking function, so a brake must be installed.
