The Optibelt ZR MXL 4040 is a timing belt with an MXL profile and a length of 1026.16 mm. It is used in light-duty synchronous drives where the belt's teeth mesh with matching pulleys to maintain position and timing.
This belt is commonly found on small precision drives such as those in instrumentation, office equipment, and light industrial machinery. The MXL profile and 1026.16 mm length identify the belt's tooth geometry and pitch length, which must match the pulleys and the drive's layout.
To confirm fit, read the marking on the back of the old belt and compare it to the profile and length shown here. Also check the pulley grooves for wear and verify that the belt's width and tooth pattern align with the pulleys. If the marking is unreadable, measure the belt's length along its pitch line and count the teeth to cross-check against the MXL profile.
When replacing a timing belt, inspect the entire drive: worn pulleys or misalignment can shorten belt life. If you need help confirming this Optibelt ZR MXL 4040 or a similar timing belt, send the part number and any photos of the old belt to our team by WhatsApp or email for a prompt quote.

Frequently asked questions
- How do I confirm that the Optibelt ZR MXL 4040 fits my drive?
- Check the marking on the back of your old belt for the profile and length. The MXL profile and 1026.16 mm length must match your pulleys and drive layout. If the marking is unclear, measure the pitch length and count the teeth to verify.
- Can you help if I only have the old belt and no part number?
- Yes. Send clear photos of the old belt, including any markings on the back, along with the pulley dimensions if possible. Our team can help identify the correct timing belt or suggest an equivalent based on the profile and length.
- What should I check on the drive before installing a new timing belt?
- Inspect the pulleys for worn grooves, check alignment between pulleys, and make sure the drive is free of debris. Worn or misaligned components can cause a new belt to fail early, so address any issues before installation.
