[ ! ]Shaft Bore diameter 6.35 is available for Straight Bore and Straight Bore + Tap.
[ ! ]Shaft bore dia. 9 is not available for Keyway + Tap.
[ ! ]Select 10K as P dimension if you request keyway width of 4.0mm (height 1.8mm) for Keyway + Tap with shaft bore diameter of 10.
[ ! ]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 s generated by the gears.
