When connecting the load, be sure of alignment of the center, tension of the belt, and
parallel of the pulley. When connecting the load such as a pulley or a belt, be cautious of the
allowable thrust load, radial load, and shock, as well as tighten the screw for a coupling or a
pulley not to be unscrewed.
When attach a coupling or a pulley to the shaft, be cautious of damage on shaft or bearings
and it is banned to disassemble or change structure of the device or the shaft for connecting
with a load.

use flexible coupling as image showing above. If the center of the load and the shaft is not
aligned, it may cause severe vibration, damage on shaft or shortened life cycle of bearings.
