Screw shields, also known as a shield screw protective cover, it can effectively protect the screw from dust, light bars, shafts, columns and other parts external characteristics of the pollution and destruction. Screw shield processing methods, as well as taking into account the factors of different materials suitable for different processes can be divided into two forms. Screw shield a steel ring support, such a guard using a variety of fabrics, with a stiff wire ring support at high temperature 110 ° C, -40 ℃ low temperature between normal work. Can be effective dustproof, waterproof, anti-oil, anti-emulsion and chemicals, this shield shape neat, is not easy deformation characteristics, based on its tight, strong guard and can be used for a number of mechanical ventilation, dust and other. The flexibility of the product not only in the material optional, but also in that it can be according to the specific requirements to determine the required diameter and length. Another is sewn screw protective cover, a circular screw shields are stamped wafer sewn into the two adjacent inner edge, the two outer sewn together by sewing can be achieved better shape stable and firmly in the horizontal direction. The material can have a variety of options, depending on the working environment. Screw shields Material: artificial leather cloth, nylon cloth, insulating membrane, rubber composite fabric, anti tarpaulins, tarps, flame retardant fabric, acid cloth, dark green cloth, three anti-cloth and other materials are able to do with the parts stretched or compressed motion, vertical or horizontal use can. Horizontal position, using a support ring of plastic or aluminum, to maintain a uniform distance between the shroud cavity with the lead screw and prolong life. Stretched length each compromise together with a metal ring to improve the stability of the shroud. Use metal flange connection or fixed end, or select ferrule Grey all the staff look forward to working with you for your cooperation
