Description
MITSUBOSHI BB 118 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 118 and any equivalents.
This Mitsuboshi BB 118 is a double-V (hexagonal) belt in the BB profile. Double-V belts are used where a drive needs power transmitted from both sides of the belt, such as reversing or multi-pulley drives. Confirm fit by the profile and the part number.
To confirm this belt fits your drive, read the marking on the back of the old belt and match it to the BB profile and the BB 118 part number. Check that the pulleys are double-V (hexagonal) pulleys, since a double-V belt runs on both its top and bottom faces. If the old belt is worn or the drive has more than one belt, inspect the pulleys and replace the full set so the belts share the load evenly.
The same size is also listed under Optibelt BB 118, Dayco BB 118 and Gates BB 118. If you are matching a belt already in service, send the part number and a photo of the back marking. Our team can help confirm the right belt or suggest an equivalent.
