[ ! ]Shaft Bore Dia. 9 is not available for Keyway+Tap. [ ! ]Combine the same handedness (L and L or R and R) for unparallel shafts and different handedness (L and R) for parallel shafts.
[ ! ]Helical gears generate axial thrust on shafts. Choose bearings that can withstand the axial thrust generated by the gears.
