The Optibelt B 45 is a classical V-belt in the VB / HVAC Power series, built for drives that call for a B profile. Its 1219 mm length, 17 mm top width, 11 mm height and 40° angle suit the dimensions of the existing pulley groove. Confirm those values against the belt you are replacing before you order.
Classical V-belts of this profile are common on HVAC air-handling units, fans, blowers and light industrial drives where a single B-section belt runs between two pulleys. The 40° angle and 11 mm height are matched to standard B grooves, so the belt should sit in the pulley without riding high or bottoming out.
To confirm fit, read the marking on the back of the old belt and compare it with B 45. Then check the profile and the 1219 mm length against the drive. If the old belt has stretched or worn, measure the pulley grooves and the center distance rather than relying on the used belt alone. The same size is also listed under Stark B 45, which gives you a second option to ask about.
Send the part number, the profile and the length in your quote request, along with a photo of the belt marking if it is readable. We carry Optibelt belts and can help confirm the right B 45 for your drive or suggest an equivalent.

Frequently asked questions
- How do I confirm the B 45 is the right belt for my drive?
- Match the profile B, the 1219 mm length, the 17 mm top width, the 11 mm height and the 40° angle to the old belt and the pulley grooves. If the marking is worn, measure the groove width and the drive center distance.
- What should I send with my quote request?
- Send the part number B 45, the profile and length, and a photo of the back of the old belt if the marking is readable. If you are unsure of the size, include the pulley dimensions and center distance.
- Is the same size listed under another brand?
- Yes. The same size is also listed under Stark B 45, so you can ask about that option when you request a quote.
