This Optibelt AT5 300 timing belt is part of the Alpha Power series. It has an AT5 profile, a 300 mm length and a 5 mm pitch. Use these three values to match it against the belt you are replacing.

The simplest way to confirm a match is to read the marking on the back of the old belt. Look for the profile and the length together: AT5 and 300. If the old belt is worn or the print is gone, measure the pitch and the overall length and compare them to the 5 mm pitch and 300 mm length listed here.

Because this is a synchronous belt, the teeth engage the pulley rather than relying on friction. A correct match depends on the profile and length, not on the width alone. If the drive uses more than one belt, replace them as a set so the load stays even across the pulleys.

Send the part number AT5 300, or the marking from the old belt, by WhatsApp or email. If you are unsure whether this is the right belt for your drive, include a photo of the old belt and the pulley. We carry Optibelt and can help confirm the right belt or suggest an equivalent.
