High Torque Timing Pulleys S5M 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.
