MISUMI
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 TPC "tap hole dimensions" or changing to shape B. Thank you for choosing this product.
- Please check the content on our website as the PDF does not contain the most up-to-date information.
