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

[ ! ] For aluminum flanges, the flange thickness is 1.5.
[ ! ] 1 The number of teeth 33, 34, 49 to 60 toothed pulleys is t=2.0 (Machined Flange)
[ ! ] 2 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.
[ ! ] The tolerance of the tap position dimension from the boss end face and pulley end face is ±0.3.
[ ! ] 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 the shaft bores.

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.

V stepped hole

F Stepped Hole (Counterbored
Hole on the Hub Side)

Y Both Ends Stepped Hole

WB Two-stepped hole
