Tooth groove dimensions slightly vary according to the number of teeth. (Pitch: 2.0 mm)
[ ! ] The tolerance of the tap position dimension from the boss end face and pulley end face is ±0.3.
[ ! ] Shaft Bore Specs. H (Round Hole), V, F, Y, and WB (Stepped Hole) do not have tapped holes and set screws.
[ ! ] Unless otherwise specified except for teeth and F dimensions, the dimension tolerance conforms to JIS B 0405 Class m.

● Shaft Bore Specification Select shaft bore spec mark and each dim. from the table below.
[ ! ] Surface treatment may not be applied to shaft bores.
[ ! ] No standard value is specified for chamfering of d dim.

H Round Hole

P Round Hole + Tap

N New JIS Keyway + Tap
C Old JIS Keyway + Tap

[ ! ] For A-Shape pulley, the screw
holes are set at around 120° to
keep away from peaks.

[ ! ] Specify NK10 when selecting "New JIS Keywayed Bore" + "Shaft Bore Diameter 10" + "Keyway Width 4.0 mm".
[ ! ] The difference between part number N10 and NK10 is the machining dimensions. See the table below, "New JIS Keyway Dimension Tolerance," for details.
