[8mm Hexagon Hole to 8mm Hexagon Hole]

Feature:
1. The parts are connected and fixed by clamping, which will not cause any damage to the fixed parts, and can produce super clamping force on the hexagonal shaft.
2. The clamping mechanisms at both ends are independent of each other and are clamped by double bolts. When clamping the shaft, it is not necessary to insert the shaft at both ends at the same time.
3. Taking the center hole as the benchmark, it can effectively avoid the centrifugal force and vibration caused by the unbalanced mass and volume of the parts in high speed applications.
4. It has a long clamping length, which greatly increases the contact between the shaft and the surface of the center hole, and greatly increases the clamping force and the pressing area.
5. There are two clamping bolts at each end, and the two bolt setting at both ends of the balance will produce a balanced and firm clamping force on the shaft.


How to Use:
Since the outer diameter is small enough, it will not affect us to fix the motor on the U?shaped beam with a hex wrench because the outer diameter is too large. Because the length is short enough, we can insert the coupler into the shaft tip of the motor and the opposite U?shaped beam. Between beam and wall. This makes it possible to add the coupler to the assembly after the motor is fixedly installed on the U?shaped beam, or to remove it from the assembly without removing the mo
