Description
OPTIBELT BB 55 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 55 and any equivalents.
The Optibelt BB 55 is a double-V (hexagonal) belt in the DK series with a BB profile. It is built to run on both sides, which suits drives that need power transmitted from either face. If you are replacing an existing belt, start by reading the marking on the back of the old belt.
The marking on a double-V belt usually shows the profile and the part number. On this belt that is BB and BB 55. Confirm both before you order, because a belt with the same length but a different profile will not sit correctly in the pulley grooves. The same size is also listed under Stark BB 55, Dayco BB 55 and Gates BB 55.
Once you have confirmed the marking, check the drive for worn pulley grooves, misalignment and any debris that could damage the belt. Double-V belts are often used where a drive has pulleys on opposite sides, so inspect both sets of grooves. If the old belt is stretched, cracked or glazed, replace it rather than reinstalling it.
When you request a quote, send the part number BB 55 and the brand Optibelt, along with the profile BB and the belt type. If you are unsure whether this is the correct belt for your drive, send a photo of the marking on the old belt. The team can help confirm the right belt or suggest an equivalent.
