The Optibelt ZR DL 390 is a double-sided timing belt with a 990.6 mm length. This profile and length define how the belt fits a drive where both sides engage pulleys.
When selecting a replacement, the ZR profile and 990.6 mm length are the key dimensions to match. The double-sided construction allows the belt to drive pulleys on both faces, which is common in reversing or multi-pulley layouts.
To confirm the correct fit, check the marking on the back of your old belt. The part number DL 390 and the 990.6 mm length should match what is printed. If the marking is worn, measure the old belt and note the profile.
We carry the Optibelt ZR DL 390 and can help you verify it against your application. Send the part number, the belt marking, or a photo via WhatsApp or email, and our team will reply promptly with a quote or a suitable equivalent.

Frequently asked questions
- What does the ZR profile indicate on this belt?
- The ZR profile is a specific tooth profile used in timing belts. It determines how the belt meshes with the pulleys. The DL 390 is a double-sided version of this profile.
- How do I confirm the 990.6 mm length is correct for my drive?
- Check the marking on your existing belt. If it shows DL 390 and 990.6 mm, it is the same length. If the marking is unreadable, measure the old belt or send us the drive details for verification.
- Can you help if I need a different length or profile?
- Yes. Send us the part number, belt marking, or a photo of the old belt. We will confirm the correct Optibelt ZR DL 390 or suggest an equivalent based on your requirements.
