Screw shaft guards, also known as screw shaft sleeves, are a type of protective cover that effectively shields screw shafts, light shafts, shafts, pillars, and other components from dust and other external contaminants and damage.

The products are categorized by manufacturing process into steel ring-supported and stitched types. By shape, they include cylindrical, tower, square, rectangular, elliptical, stair, crescent, and semicircular shapes, among others. Connection methods include: (1) Both ends with collars (grommet style), (2) Both ends with flanges (screw style), and (3) One end with a flange and one end with a collar. Flanges are further divided into PVC flanges and metal flanges.

Steel ring support

Available in various fabrics, supported by steel wire rings, and constructed with high-frequency heat-sealed sleeves, featuring a fixed outer diameter. It operates normally between 110℃ and -40℃. It effectively prevents dust, water, oil, emulsions, and chemicals. Known for its neat appearance and resistance to deformation, it is suitable for ventilation and dust removal in numerous machinery. The required diameter and length can be determined based on the specific customer requirements.

Sewn

A variety of materials are available based on different working environments. The product is first formed into discs through stamping and sewing. The two inner edges and two outer edges are stitched together, which achieves good shape stability and firmness in the horizontal direction through the sewing process. Installation methods include whole, zipper, hook-and-loop, and snap styles, offering greater convenience for the user's installation.

The component can be extended or compressed, suitable for both vertical and horizontal use. When in a horizontal position, plastic or aluminum support rings are used to maintain a uniform distance between the protective cover and the screw, thereby extending the service life. For greater stretch lengths, a metal ring is added to each fold to enhance the stability of the cover. Metal flanges are used for connection or fixation, or a sleeve-type option can be chosen.
