Installation time comparison~Difference in number of bolts

We compare the mounting time of PSL-G (wedge system) and ETP-E Plus (hydro system) friction fasteners.
It takes approximately three minutes to fasten an axis and hub with a wedge system friction fastener. However, it is possible to fasten an axis and hub with a high degree of accuracy in approximately 20 seconds by using a hydro system friction fastener (degree of concentricity: 0.02 mm).
In addition, anyone can fasten the axis and hub with one bolt. Therefore, skilled techniques are not required.
It is possible to obtain a significant man-hour reduction effect by introducing hydro system friction fasteners for parts that need to be removed frequently.
