High Torque Timing Pulleys P2M/P3M Type
Caution
- Please note that the swaged flange options, NFC, RFC, and LFC, are not reflected in the CAD data.
- For customers who are selecting timing pulley with tapped holes on the tooth surface. Depending on the shaft bore diameter selected by the customer, the accessory set screw may protrude and interfere with the belt. Please check whether the set screw protrudes from the bottom of the pulley root on the 3D preview or CAD. If it protrudes, please consider alteration SLH "Set screw length change" or changing to shape B. Thank you for choosing this product.

[ ! ] 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 and set screws.
It may have a relief in the tapped hole depending on its size.
[ ! ] 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.
[ ! ] Shaft Bore Dia. 4.5 and 6.35 are selectable within Shaft Bore Dia. d for Shaft Bore Specs. H, P, V and F.
[ ! ] Specify NK10 if keyway width of 4.0 mm (height 1.8 mm) for shaft bore spec. N and shaft bore diameter of 10 is desired.
[ ! ] For A-Shape pulley with shaft bore spec. P, N, or C, the screw holes are set at around 90° to keep away from peaks.
