[ NG ]Shaft bore diameter 9N is not available for Keyway Bore+Tap. [ NG ]When specifying "Straight Bore+Tap" and "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.
[ ! ]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. >> Click here
[ ! ]When requesting Shape A (no hub), specify W=0
[ ! ]When W=0, specification for H is not required.
[ ! ]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)
