This Optibelt SPZ 1120 is a narrow wedge V-belt from the SK metric profile line. It is used on industrial drives where a compact, high-grip belt is needed to transmit power between small-diameter pulleys. Confirm fit by matching the profile and the 1120 mm length to your drive.
The SPZ profile measures 9.7 mm across the top, 8 mm high, with a 40-degree angle. The belt length is 1120 mm. These dimensions suit drives that run SPZ-section pulleys and require a belt that seats correctly without bottoming out in the groove.
To confirm the right belt, read the marking on the back of the old belt and compare it with the profile and length above. Check the pulley grooves for wear and make sure the new belt sits at the correct height. If the drive runs multiple belts, replace them as a set so the load stays even.
The same size is also listed under Mitsuboshi SPZ 1120. Send the part number and the belt marking by WhatsApp or email, and the team can confirm the correct belt or suggest an equivalent.

Frequently asked questions
- What does the SPZ 1120 marking tell me?
- The SPZ is the profile and the 1120 is the length in millimeters. Match both to the marking on your old belt to confirm the replacement.
- Can I use this belt if my drive runs several belts?
- Yes, but replace all belts on the drive at the same time. Mixing a new belt with worn belts can cause uneven loading and premature failure.
- How do I request a quote for the Optibelt SPZ 1120?
- Send the part number and the marking from your old belt by WhatsApp or email. The team will confirm the belt and reply with a quote.
