Description
STARK B 40 belongs to v-belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for B 40 and any equivalents.
The Stark B 40 is a classical V-belt with a B profile, a 17 mm top width, an 11 mm height and a 40° angle. When you are replacing a belt, matching those dimensions to the belt you remove is the first check. The same size is also listed under Optibelt B 40.
To match the belt being replaced, read the marking on the back of the old belt and compare it with the Stark B 40. Confirm the profile is B, the top width is 17 mm, the height is 11 mm and the angle is 40°. If those values match, the belt is the same size as the one in service.
The same size is also listed under Optibelt B 40, so you can use that as a second reference when checking the old belt. If the marking is worn or missing, measure the cross-section and note the profile and dimensions before requesting a quote.
Send the part number Stark B 40, or the dimensions from the old belt, by WhatsApp or email. The team replies promptly and can help confirm the right belt or suggest an equivalent.
