Description
OPTIBELT BB 74 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 BB 74 and any equivalents.
This is an Optibelt BB 74 double-V (hexagonal) belt from the DK series, with a BB profile. To match it to the belt you are replacing, read the marking on the back of the old belt and confirm both the profile and the part number. The same size is also listed under Mitsuboshi BB 74 and Gates BB 74.
A double-V belt drives from both sides, so the replacement must match the profile and the length exactly. The profile is BB. If the old belt is worn or the marking is unreadable, measure the outside length and compare it with the part number before you order. Do not substitute a single-V belt for a double-V belt.
When you request a quote, send the part number BB 74 and, if you have it, a photo of the marking on the back of the belt. If the drive runs more than one belt, note the quantity so the set can be matched. We carry Optibelt and can confirm the right belt or suggest an equivalent.
