The Optibelt DT5 400 is a double-sided timing belt from the Alpha Power series. It measures 400 mm in length. Double-sided timing belts are used where a drive needs synchronized power taken from both faces of the belt, such as reversing or dual-output arrangements on industrial machinery.
Confirming fit starts with the belt you are replacing. Read the marking on the back of the old belt and compare it against the part number and length on this page. A double-sided belt must match the pulley profile on both faces, so check that the drive uses toothed pulleys on each side before ordering.
Because both faces carry teeth, these belts are not interchangeable with single-sided timing belts of the same length. If the old belt is worn, cracked at the tooth roots, or showing exposed cord, replace it rather than reinstalling it. On drives running two belts, replace both at the same time so the load stays even.
Send us the part number, the belt marking, and the length you need. Our team can confirm the Optibelt DT5 400 against your application or suggest an equivalent, and we reply by WhatsApp or email.

Frequently asked questions
- What is a double-sided timing belt used for?
- It is used on drives that need synchronized motion from both faces of the belt, such as reversing or dual-output arrangements. Both sides carry teeth, so both pulleys in the drive are toothed.
- How do I confirm this belt fits my drive?
- Compare the part number and the 400 mm length against the marking on your old belt, and check that both pulleys are toothed. If anything does not match, send us the details and we will help confirm the right belt.
- What should I send for a quote?
- Send the part number Optibelt DT5 400, the marking from the old belt, and the length. A photo of the belt and the drive helps us confirm the match or suggest an equivalent.
