This Optibelt 3V 1120 is a narrow wedge V-belt from the SK S=C Plus series. It has a 3V profile and a length of 2845 mm. Use this page to confirm it matches the belt you are replacing.
The most reliable way to match a belt is to read the marking on the back of the old belt. Look for the profile and the length: here that is 3V and 2845 mm. If the old belt is worn or the marking is gone, measure the outside length and compare it to 2845 mm. The 3V profile is a narrow wedge cross-section, so a standard V-belt of the same length will not fit the same pulleys.
The same size is also listed under Stark 3V 1120, Mitsuboshi 3V 1120, and Dayco 3V 1120. If you prefer one of those brands, we can quote the equivalent size. When you request a quote, send the part number 3V 1120 or the profile and length 3V and 2845 mm. If you are unsure, send a photo of the belt marking and the pulley grooves.
For drives with multiple belts, replace all belts in the set at the same time. A new belt running next to worn belts can carry more than its share of the load. Check pulley grooves for wear and alignment before installation, and set tension according to the drive manufacturer's specification.

Frequently asked questions
- How do I confirm this belt matches the one I am replacing?
- Check the marking on the back of your old belt for 3V and 2845 mm. If it matches, this Optibelt 3V 1120 is the same profile and length. If the marking is unreadable, measure the outside length and compare it to 2845 mm.
- What should I send to get a quote?
- Send the part number 3V 1120, or the profile and length 3V and 2845 mm. If you have the old belt, a photo of the back marking helps us confirm the correct belt.
- Can I use a standard V-belt instead of this narrow wedge belt?
- No. The 3V profile is a narrow wedge cross-section. A standard V-belt of the same length will not seat correctly in the pulley grooves. Use a belt with the 3V profile and 2845 mm length.
