When replacing a double-sided timing belt, the most reliable approach is to match the belt you remove. This Optibelt Omega belt is identified by its 645 mm length and D5M profile, with a 15 mm width. Use the markings on the old belt to confirm these three details before ordering.
Start by reading the back of the belt you are replacing. You are looking for the length, profile, and width. This belt is 645 mm long, has a D5M profile, and is 15 mm wide. If those three match your old belt, this Optibelt Omega double-sided timing belt is the correct replacement.
Double-sided timing belts are used in drives that require power transmission from both sides of the belt. Because both faces have teeth, correct installation matters. Confirm that the belt path and pulley arrangement match the original setup. If the old belt is worn or damaged, check the pulleys for wear or debris before installing the new belt.
If you cannot read the markings, measure the old belt. Lay it flat and measure the length in millimeters. The profile is determined by the tooth pitch and shape; D5M is a specific profile. The width is measured across the belt. If you are unsure, send a photo of the old belt and any markings to our team for confirmation.
