4144525 PIN SPRING For HITACHI ZX330-5A 6HK1

The specific uses of spring pins include: positioning : used to determine the relative position between parts to ensure the accuracy of assembly. Connection ‌ : as a connection, join different parts or assemblies together. Fixed ‌ : to ensure that the parts will not easily move or fall off after assembly, to maintain the stability of the structure. In addition, spring pins are also divided into toothed elastic cylindrical pins and toothless elastic cylindrical pins.

Spring pin, also known as elastic cylindrical pin, is a headless hollow column shape, axially slotted, with chamfer at both ends, used for positioning, connecting, fixing and so on between parts. The spring pin needs to have good elasticity and shear resistance, and its outer diameter is slightly larger than the assembly aperture. To ensure that it is firmly fixed in position to prevent the relative movement or loosening of the parts. The main categories of spring pins include light elastic cylindrical pins and elastic cylindrical pins with teeth ‌, coil elastic cylindrical pins.

Spring pin is generally composed of elastic elements and pin body two parts, its role is mainly to connect, fix or transfer force. Among them, the elastic element has a certain elasticity and shear resistance, which can keep the pin body stable when connecting or transferring force to prevent loosening or falling off. Therefore, spring pins are widely used in various mechanical manufacturing. Spring pins can also be used for power transmission, such as connecting two drive shafts or drive wheels. In the power transmission, the spring pin can reduce vibration and shock, and maintain the smooth and stability of the transmission.
