introduction

Cold-formed cylindrical coil spring is a commonly used elastic element, widely used in machinery, chemical industry, aviation, construction and other industries. Cold-formed cylindrical coil springs made of circular cross-section materials with a diameter of 0.16mm~0.48mm are small cylindrical coil springs. GB/T 1973 Small Cylindrical Coil Springs is divided into 3 parts. --- Part 1.Technical conditions. The purpose is to give the technical requirements, test methods and inspection rules of small cylindrical coil springs and Packaging, marking, transportation and storage requirements. --- Part 2.Dimensions and parameters of tension springs. The purpose is to give the marking, dimensions and parameters of small cylindrical helical tension springs. --- Part 3.Dimensions and parameters of compression springs. The purpose is to give the marking, dimensions and parameters of small cylindrical helical compression springs. Small cylindrical coil spring Part 3.Dimensions and parameters of compression springs
