The scope of application of BL rod pin coupling
It is suitable for the transmission shaft system connecting two coaxial lines, and has the ability to compensate the relative deviation of the two shafts and general shock absorption performance.The working environment temperature is -20º~+70ºC. It is not suitable for parts that require high shock absorption effect and need to control noise.
