The Optibelt 25 AT5K6 / 3600 AFX is an Alpha Flex timing belt with an AT5 profile, a 3600 mm length and a 5 mm pitch. Before you fit it, inspect the drive and the sheaves so the new belt runs true and lasts.
Check each sheave for worn grooves, burrs, corrosion or buildup, and confirm the teeth are clean and undamaged. Misaligned or worn sheaves will shorten the life of any timing belt, including this AT5 profile belt. Verify that the sheave tooth form matches the AT5 profile and that the 5 mm pitch is correct for the drive.
Measure the old belt and compare it with the 3600 mm length before ordering. Confirm the width and tooth profile from the marking on the back of the belt, and note the part number 25 AT5K6 / 3600 AFX. If the drive uses more than one belt, replace the set together so the load is shared evenly.
When you request a quote, send the part number 25 AT5K6 / 3600 AFX, the profile AT5, the length 3600 mm and the pitch 5 mm. Our team replies by WhatsApp or email and can help confirm the right belt for your drive.
