OEM Available Retractable Spring Powerful Springs Extension Spring
Extension Spring is a typical Spring, namely the representative of Spring, from straight cylinder to various variants, and even hook shapes can be shaped according to the design.
The Extension Spring is the reverse application of the compression Spring. The application scope is roughly less specific than the product category, but the operation control is one level higher than the compression Spring.
Compression Spring
Each ring is divided into winding, because it can withstand pressure, both ends can be open or closed, winding or grinding flat. The following is the necessary information of a compression spring:
(1) Controlling diameter (a) outer diameter, (b) inner diameter, (c) the inner diameter of the casing, (d) the outer diameter of the round rod.
(2) Wire or bar size.
(3) Materials (type and grade).
(4) number of turns :(a) total number of turns and (b) right or left.
(5) Style of ends
(6) Load at a certain length of torsion zone.
(7) Load ratios ranging from one inch to several inches in length.
(8) Maximum solid height.
(9) Minimum compression height when used.
