SJA series screw jack

The patented external shape design-unique rectangle fluted housing of the screw jack increases the heat-dissipation ability of the housing and extend the lifetime of the lubricant etc. The material of ductile cast iron raises the hardness and increase the efficiency and the wide application in low or high temperature environment of the housing. The design of the rectangle rear tube prevents the screw from self-rotating and the safety nut offers a guarantee to the security of the screw jack and monitors the wear degree of the nut.The advanced manufacturing equipments and assembling technique ensures the high quality of the products, leading designing concept creates superior products featuring in the strong shock-load resistance, high duty cycle, low noise, long lifetime and small size.
