Screw elevator
The unique square groove shell of ELITE screw jack increases the heat dissipation capacity of the shell and prolongs the service life of grease. The selection of the shell material of ductile iron greatly improves the strength and performance of the shell, and it is widely used in high/low temperature. The square tail cover design, the control screw does not rotate. Advanced processing equipment and processing assembly technology are the guarantee of high product quality. Advanced design concepts create high-quality products with strong impact resistance, high strength, low noise, long life, and small size.
Modular combination enriches product combinations. The screw jack can be directly combined with any combination of motor/gear motor/special function accessories. The integrated design provides customers with thousands of easy choices. For specific parameters, consult the local office.
Non-standard designs can be made according to customer requirements, such as stainless steel housings and screw jacks, multi-head screws, high temperature resistance, low temperature resistance and other products.
Complete accessories: dust cover, anti-backlash design, safety nut, ball screw, limit switch, overload clutch, potentiometer, encoder, brake, hand crank, installation accessories, etc.
