High load capacity cylinder ELZ series

electrictrapezoidal screwworm gear

FREN Electric cylinders are an advancement of our standard program. By thought construction is an electrical cylinder in the situation also components out to be taken up. The lift link inside electrical cylinders is protected by the tubing system from any damage by environmental influences and is approximately to rotate secured. In the FREN Electric cylinder there is a robust worm gear pair driving a trapezoid thread spindle. The gear box is made of nodular graphite cast iron 50 fit high loads and meeting high safty standards. The worm is hardened and ground and running on tapered roller bearings. The worm wheel is made of high-strength material which is particularly resistant to abrasion; it is mounted between deep groove ball thrust bearings. The thrust tube consists of steel and is outside polished and chromium plated. The spindle ends can be supplied after customer's request also stainless. The ELZ5 to ELZ350 line ist the worm gear alternatively filled with grease or oil and the tubing system is lubricated with grease on delivery and fit for operating temperatures ranging between -30°C and +80°C. To be increased the trapezoid thread spindle is the life span additionally coated with lubricating varnish by better fail-safe characteristics to be achieved and thus.The operating factor at maximum load is 20% per hour 30% per 10 minutes. The trapezoid thread spindles are stand single-threas double-thread three-thread and fourthread execution. For higher demands with regard to lifting speed and operating factor we use ball screw spindles. FREN Electric cylinders are fitted with blue prime coat (RAL 5012)
