[ NG ]Shaft bore diameter 9N is not available for Keyway Bore + Tap. [ NG ]When specifying "Straight Bore + Tap" or "Keyway + Tap," make sure that the hub length satisfies the condition of "(W)>M+3."
[ ! ]When the tooth width is smaller, the transmitting torque is smaller. [ ! ]Shaft bore diameter 6.35 is available for Straight Bore and Straight Bore + Tap.
[ ! ]Specify 10K as the P dimension if keyway width of 4.0mm (height 1.8mm) for Keyway + Tap with shaft bore diameter of 10 is desired.>> Click here
[ ! ]When requesting Shape A (no hub), specify W=0
[ ! ]When W=0, specification for H is not required. [ ! ]The "-" text on the above table means that any Shaft Bore Dia. is not selectable.
[ ! ]For WDH alterations, the H range requirements considered as Q and R = P must satisfy the condition of "Q + ○ ≤ H ≤ G - ○, R + ○ ≤ H ≤ G - ○." (○: Refer to the value in the specification table)
[ ! ]For DHL/DHR alterations, the H range requirements considered as Z = P must satisfy the condition of "Z + ○ ≤ H ≤ G - ○." (○: Refer to the value in the specification table)
