The AT5 profile and 5000 mm length are the key dimensions for this belt. The 5 mm pitch is fixed by the profile. If your current belt is worn, check for cracks, missing teeth, or exposed tensile cords. Confirm that the width and tooth profile match your pulleys before ordering. If you are unsure, send the old belt's marking and we will help verify it.
For replacement, inspect the pulleys for wear, debris, or damaged teeth. Check that the belt tracks correctly and that the tension is set according to your equipment manual. If the drive uses multiple belts, replace them as a set to maintain even load sharing. After installation, run the drive and recheck tension.
