[ ! ]

Tooth groove dimensions slightly vary according to the number of teeth. (Pitch: 5.08 mm)

[ ! ] Compliant with JIS B 0405 Class m
(Medium Class).

[ ! ] For aluminum and stainless steel flanges, the flange thickness is 1.5.
[ ! ] 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 or F (Stepped Hole), Y (Both Sides Stepped Hole) and WB (Two-stepped Hole) do not have tapped holes.
[ ! ] Unless otherwise specified except for teeth and F dimensions, the dimension tolerance conforms to JIS B 0405 Class m.

● 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.
[ ! ] The position of the keyway and the phase of the teeth are not guaranteed.
