Lower cost universal joint shaft coupling comes with shaft hole diameter D1 120mm, outer diameter 70mm. The compact universal joint shaft coupling has the advantages of high accuracy, high precision and long service life.

Features

• The structure is reasonable, the use is safe and reliable, and the integral fork head is adopted, which eliminates the weak link of the bolt pressing the bearing seat (cover), and completely avoids the common vicious damage caused by the loosening or breaking of the bolts.
• The service life is 30%-50% higher than other types of couplings.
• High carrying capacity.
• The transmission efficiency is high, the transmission efficiency is as high as 98.7%-99.9%, and the energy saving is remarkable when used in high-power transmission, which can reduce power consumption by 5%-15%.
• The transmission is stable and the noise is low, the general noise is 30-40dB(A).

Application

Tips: What is the use of universal coupling?

A universal coupling is a linkage or joint between two shafts, for example, a driving shaft and a driven shaft, which permits rotation of the shafts when their axes do not coincide. Such couplings are very widely used, for example, in machine tools, instruments, control devices, and automobiles.
