Professional production of high-quality screw dust cover dust jacket also called screw screw shields, also known as retractable protective sleeve. Uses screw dust cover: Protection of screw, light bars, columns, shafts and other rotating parts from dust and other debris from oil pollution damage. This product is made of nylon fabric, insulation sheet, rubber echoed cloth, anti-tarpaulin, tarpaulins, flame retardant cloth, acid cloth and other materials are available to be tailored to the different needs of customers. Elongation and compression ratio generally sheath 1000: 150 (also vary according to the actual diameter), the product shape can be designed and manufactured according to the customer, polygonal screw shields, screw shields rectangular, cylindrical screw Requirements shield, also according to user requirements ratio larger or smaller sheath. With the mechanical components can stretch or compress for sports, diameter, stretching the length of the connection methods can be bent without restriction. Can be mounted using mechanical internal or external, vertical or horizontal. Screw protective cover with dust, water, oil, anti-emulsion and chemicals, anti-iron, tensile resistance, impact deformation, corrosion resistance and long service life. Protective sleeve to be protected by installing parts mating flanges at both ends, with the implementation of non-contact coupling guard. The protective sleeve and on the connection between the flange is to rely on the security of its own pre-compression elasticity achieved, so running the job stability, flexibility, and low noise, and its surface is glossy black, and most of the law on the machine Portland pieces coordination. Users can also request the production of white protective cover screw (screw heat protective sleeve). Yu Rui welcome to visit the factory inspection, consultation orders.
