JTE Series Electric Cylinders description

JTE Series Electric Cylinders are basically screw jacks with travelling nut, but with lifting cylinder design. Combined the advantages of Linear actuator and Screw Jack to achieve the high load lifting in industry application. Available in Ball Screw and Acme Screw. The screw is fully enclosed by push rod which is guided in external protection tube, that is well suited for industrial environments where protection of the lifting screw mechanism and dependable operation are critical, and the protection level can reach IP55, IP56. As a better choice over hydraulic actuators or pneumatic cylinders with this clean alternative, easy to install, control, low maintenance and a quieter solution. In the absence of vibration load, Electric Cylinder with acme screw has self-locking and precisely position loads, will hold loads without backdriving. But Ball Screw Electric Cylinder has not self-locking, brake motor is required.
JTE Series Electric Cylinders Actuators lift and precisely position up to 20 tons. They are widely application in tunnel freezers, frying machine, polysilicon ingot furnace, monocrystalline silicon in the photovoltaic industry, vehicle lifters in the vehicle manufacturing industry, flexible tooling and welding lifts, medical devices, woodworking machinery, food machinery, aerospace, defense military, and astronomical telescopes remote control actuators.



The JTE Series Electric Cylinders can be ordered to accept the motor type of your choice, whether geared motor, or AC motor etc. Available in Standard(double input shafts), Direct Motor Mounts and Parallel Motor Mounts with additional Gearbox.


Electric Cylinders Features:
* Available in Acme Screw and Ball Screw, precise positioning, and uniform speed. 
* Load capacity range from 2.5 ton to 20 ton. 
* There are no "standard" travel lengths. each electric cylinder is built to specification.
* Machine Screw Ends: Threaded End, Top Plate, Clevis End, Rod End, and Fork Head.
* Can be operated by manually operated or by electrically driven.
* Double seal to prevent abrasive particles and contaminants from entering the actuator critical mechanisms, and assures trouble-free operation even in most severe environments.
* Synchronized Lifting System, 2-16 pieces Actuators could be driven by one motor.
* Standard Electric Cylinders are purchased without a motor or external gearbox (reducer). NOTE: Brake motors must be specified for all Ball Screws Electric Cylinders. and for any Acme Screw Electric Cylinder with an efficiency ratio greater than or equal to 30%.

Electric Cylinder Actuator Material
* Acme Screw: Carbon steel #45. Custom stainless steel.
* Translating Tube(Push Rod): High strength steel. Custom stainless steel.
* External Protection Tube: High strength steel. Custom stainless steel.

Permissible Critical Bucking Force of Electric Cylinders
The primary electric cylinder actuators size selection factor is the bucking resistance of screw shaft, Also know as Euler cures, the graphs (Euler 2: Guided) below give safety operating state for each size of electric cylinder. Buckling limits are relevant for compressive load only.
