The Optibelt ZR DL 187 is a double-sided timing belt with a length of 476.25 mm. It is built for drives where both faces of the belt must transmit timing, such as reversing or twin-shaft arrangements. Confirm fit by checking the belt marking and the drive's pitch and width.

Double-sided timing belts are common on applications where two shafts must turn in opposite directions from a single drive, or where a belt must engage pulleys on both sides. The DL 187 carries timing teeth on both faces, so it can drive two pulleys from opposite sides without a separate idler or twist. The 476.25 mm length is the datum length for this belt; verify it against the old belt's marking before ordering.

To confirm fit, read the back of the old belt. You should find the Optibelt name, the ZR series, and the DL 187 code, along with the length. Compare that to the drive's pulley pitch and width, and check that the belt path allows both faces to engage their pulleys. If the marking is worn or missing, measure the old belt's length and count the teeth to match the 476.25 mm figure.

When you request a quote, send the part number DL 187 and the belt marking from the back. If you have the old belt, note the tooth profile and width so we can confirm the correct replacement. We carry the Optibelt ZR line and can help you match the belt to your drive.
