Available in various materials such as nylon fabric, insulating materials, rubber-backed fabric, oil-resistant fabric, waterproof fabric, flame-retardant fabric, and acid/alkali-resistant fabric, we can customize products to meet different customer needs. Customers must provide: 1. The length after stretching; 2. The thickness after shrinking; 3. The diameter of the protective part; 4. The maximum outer diameter requirement for the sheath and the connection method; 5. Technical specifications for the usage environment and material requirements. Generally, the ratio of the length after stretching to the thickness after shrinking of the sheath is 1 meter to 15 centimeters, but we can also process and manufacture products with larger or smaller伸缩 (stretch/shrink) ratios according to customer requirements.
Dustproof, waterproof, oil-resistant, emulsion-proof, and chemical-resistant, with features like anti-metal shavings, stretch-resistant, non-deforming upon impact, corrosion-resistant, and long service life. The protective sleeve is connected to the alignment flange installed at both ends of the protected component, achieving a non-contact connection with the component. The safety of the connection between the protective sleeve and the alignment flange is achieved through its inherent pre-compressed elastic force, ensuring stable operation, flexibility, and low noise during use. The surface is black and glossy, coordinating with most flange components on the machine. White screw protector sleeves can also be custom-made. The expansion-to-compression ratio of the sleeve is 1000:150, allowing it to expand or compress with mechanical components. The diameter, extension length, and connection method are not restricted, and it can be bent.
Various materials are available based on different working environments. They are first formed into discs through stamping and sewing. The adjacent inner and outer edges are stitched together, which achieves good shape stability and firmness in the horizontal direction. It effectively protects parts such as screws, shafts, columns, and more from dust and other external pollutants and damage. The circular stitched guard is made by stitching multiple discs together, with adjacent inner and outer edges stitched together, ensuring good shape stability and horizontal firmness through the stitching process.
Especially suitable for protecting small particles, it can also bear the weight generated by the particles. The circular stitched protective cover can be used horizontally or vertically. When used horizontally, it is recommended to use a plastic or aluminum support ring to maintain a uniform distance between the leather bellows and the screw, thus extending its service life. When the elongation length is large, a metal ring can be added at each fold to enhance the stability of the leather bellows. The connection or fixing end usually uses a metal flange disk, or a sleeve clamp can be chosen. Additionally, we can also provide models with side openings. This type of product can avoid the hassle of disassembling and installing for customers, more effectively improving production efficiency, saving labor and materials, and has therefore been favored by an increasing number of users.
