The Optibelt 85 / 8M 8400 AFX is a timing belt from the Alpha Flex series, built on the HTD 8M profile with an 8400 mm length and 8 mm pitch. This is a long synchronous belt for drives where tooth engagement must carry the load without slip. Use the part number to confirm the exact fit before you order.

HTD 8M timing belts are common on large, low-speed drives: main shafts, mixers, agitators, conveyors, and similar equipment where a V-belt would slip or stretch. The 8 mm pitch and 8400 mm length suit long center distances, and the teeth keep the driven shaft in step with the driver. Check that your drive uses an 8M pulley groove and that the belt width matches the pulley face.

To confirm fit, read the marking on the back of the old belt. The part number, profile, and length should match what you see here. Also check the pulley teeth for wear, the flanges for damage, and the tensioner for smooth travel. If the drive runs more than one belt, replace the set together so the load stays even.
