The Optibelt 85 / 14M 3402 AFX is an Alpha Flex timing belt with an HTD 14M profile and a 3402 mm length. It is a synchronous belt intended for drives where the pulley grooves and belt teeth must mesh correctly. Before fitting this belt, inspect the drive and sheaves so the new belt is not damaged by worn components.
Check the sheaves for worn grooves, corrosion, or debris that can affect tooth engagement. Confirm the pulleys match the HTD 14M profile and that the 3402 mm length suits the drive layout. Misalignment or a damaged sheave can shorten the life of any new synchronous belt.
When you request a quote, send the part number 85 / 14M 3402 AFX and the quantity you need. If you are replacing an existing belt, include the marking from the back of the old belt and a photo of the drive. Our team can confirm the belt or suggest an equivalent.
For drives using more than one belt, replace the set together so the load is shared evenly. Keep the old belt for comparison and note any unusual wear on the sheaves. After installation, check tension and alignment according to your maintenance procedure.
