Selecting the right option
Match the section letter and length code to the existing belt, or use a groove gauge on the pulley to confirm the section. The PIX pulley gauge is listed on the AIMS site.
These belts are ATEX certified. Confirm that this covers the requirements of your site and area classification before specifying, and contact AIMS if you need help.
The PIX catalogue pages for this product can be downloaded from the Catalogue section of this page.
Fitting and use
Fit the belts to matching pulleys and replace every belt on a multi-belt drive at the same time so the load is shared evenly. Check the pulley grooves for wear with a groove gauge before fitting new belts.
Catalogue dimensions are reference only. Contact AIMS to confirm actual measurement if a specific dimension is critical to your application.
