Round sewn organ-type protective cover
In addition to the screw lead shield, the circular sewn organ shield can also be used to protect the screw, light bar, post, mandrel and other circular rotating cylinders.
It is sewn from punched discs. Two adjacent inner edges and two outer edges are sewn together. By sewing, you can achieve better appearance stability and firmness in the horizontal direction. It can be used to protect the small volume of debris and can withstand the weight generated by the debris. If you need water and oil proof, you can apply a waterproof film to the sewing area.
It can be used horizontally or vertically. Generally, a plastic or aluminum support ring is used when horizontally used. It maintains a certain uniform distance between the shield and the screw directly to extend the service life. When the stretch length is large, a metal ring can be added to each fold to improve the stability of the shield. The connection or fixed end usually uses a metal flange, or a ferrule can be selected.
When choosing such a shield, it must be noted that the inner diameter of the shield is about 10 mm larger than the diameter of the screw rod.

The customer must provide:
First, the length after stretching;
Second, the thickness after shrinking;
Third, the diameter of the protective piece;
Fourth, the outer diameter of the sheath requires a connection method;
Fifth, the use environment and material requirements technical description.
Generally, the ratio of the length of the sheath after stretching to the thickness after shrinking is about 100: 15, and it can also be processed to produce telescopic sheath products with larger or smaller ratios.
