Screw guide guards, also known as screw guide covers, are a type of protective cover that effectively shields screws, light guides, shafts, columns, and other components from dust and other external contaminants and damage.

Process Classification

Divided into steel ring-supported and stitched styles based on production methods.

Available in various shapes such as cylindrical, tower, square, rectangular, elliptical, stair-like, crescent, and semi-circular, among others.

The connection types include: (1) Endless Neck (Buckle-style), (2) Endless Flange (Screw-type), and (3) One Flange, One Neck. Flanges are further categorized into PVC Flanges and Metal Flanges.

Steel ring support

Offered in various fabrics, supported by steel wire rings, and constructed with high-frequency heat-sealed sleeves, featuring a fixed outer diameter. Capable of operating normally between 110℃ (high temperature) and -40℃ (low temperature). Effective in dust, water, oil, emulsifier, and chemical resistance. It boasts a neat appearance and resistance to deformation. Its rigidity and tightness make it suitable for ventilation and dust removal in numerous mechanical applications. Diameter and length can be customized according to specific customer requirements.

Sewn style

Available in various materials depending on the working environment, they are first formed into discs through stamping and sewing. The two adjacent inner edges and two outer edges are stitched together, achieving good shape stability and firmness in the horizontal direction through the stitching process. Installation types include solid, zipper, hook-and-loop, and snap-button, offering greater convenience for the user's installation.

Job Characteristics

The component can extend or compress, suitable for both vertical and horizontal usage. When in a horizontal position, plastic or aluminum support rings are used to maintain a uniform distance between the protective cover's inner cavity 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 protective cover. Metal flanges are used for connections or fixed ends, or a clamping band option can be chosen.
