FAQ

What is the difference between Li (internal length) and Ld (pitch length)?

Li (1450 mm for this belt) is the measurement of the inner circumference. Ld (1485 mm), also known as pitch or effective length, is the length at the neutral axis of the belt where the reinforcing cords are located. Ld is the dimension used for calculating drive geometry and center distances.

Yes, this belt is marked as ATEX compliant. This means it has been designed and tested to be static conductive (ISO 1813), preventing the build-up of static electricity that could ignite a spark in potentially explosive atmospheres. Always verify the specific ATEX zone requirements for your application.

The UNISET marking indicates that these belts are manufactured to extremely tight tolerances. This allows you to install multiple belts on a single drive without the need for individual matching. All UNISET belts of the same size are considered a matched set, ensuring uniform load distribution and extending the service life of the drive system.
