Torison spring - Type N V&Small Cylindrically Coiled Tension Spring, Stainless Steel

Material: The diameter of the spring material is less than 0.5mm, and it is stipulated to use middle B grade steel wire or YB(T)11 group B steel wire. When using YB (T) 11 in group B steel wire, need to specify the code "S" in the mark. If other levels (groups) of materials, are agreed by the supply and demand sides and indicated in the marking.

Manufacturing accuracy: spring stiffness, outer diameter, free length of the specified 3-level precision manufacturing. If it is necessary to manufacture according to the precision of grade 2, add the symbol "2", but the width of the hook and loop opening are manufactured according to the precision of grade 3.

Rotation: The rotation of the spring is specified as right-hand rotation. If left-hand rotation is required, the symbol "LEFT" should be indicated in the marking. Hook and loop opening width: The hook and loop opening width of the spring is 0.25D~0.35D.

Surface treatment: the use of carbon spring steel wire manufactured springs, the surface of the general oxidation treatment, but can also be galvanized, cadmium-plated, phosphating, and other metal forging layer and chemical treatment.

A light spring is subjected to a force of the same magnitude in all parts whether it is in equilibrium or in accelerated motion The elongation is equal to the ratio of the force applied to the spring at any position to the coefficient of strength.

The force on a light spring with two ends connected to an object cannot change suddenly in an instant - the slow-change property of springs. The spring force on a light spring with one end not connected to an object can change to zero in an instant.

Packaging: The inner packaging is a plastic bag, and the outer packaging is a carton. Then the tray. Carton size: 29*19*19.5CM and 23.5*17.5*8CM and pallet size: 215*100*90CM, or as your request.
