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

Process Category

Steel ring supported and stitched styles, divided by manufacturing process.

Available in various shapes including cylindrical, tower, square, rectangular, oval, stair, crescent, and semi-circular, among others.

The connection types include: (1) Both Ends with Collar (Bolted) (2) Both Ends with Flange (Screwed) (3) One End with Flange, One End with Collar. Flanges are further categorized into PVC flanges and metal flanges.

Steel ring supported

Available in various fabrics, supported by steel rings, and made with high-frequency heat-sealed sleeves, the outer diameter is fixed. It operates normally between 110℃ (high temperature) and -40℃ (low temperature). It effectively resists dust, water, oil, emulsions, and chemicals. It features a neat appearance and is resistant to deformation. Its tightness and rigidity make it suitable for ventilation and dust removal in various machinery. The required diameter and length can be determined according to the specific requirements of the customer.

Sewn

A variety of materials are available based on different working environments. 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 sewing process. Installation methods include whole, zipper, hook-and-loop, and snap styles, offering greater convenience for users.

Job Characteristics

The component can perform extension or compression movements, 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 connections or fixed ends, or a sleeve-type option can be chosen.
