This Dayco BX 81 is a cogged classical V-belt in the BX profile with a length of 2133.6 mm. Cogged classical belts of this type are used on industrial drives where a raw-edged, molded-cog construction is specified, such as on older machine tools, fans, pumps and general line-shaft equipment. The same size is also listed under Stark BX 81, Optibelt BX 81 and Gates BX 81.
When confirming fit, start with the marking on the belt you are replacing. The profile must read BX and the length designation must match 81, which corresponds to 2133.6 mm in this listing. If the old belt is worn or the marking is unreadable, measure the outside length and compare it to the length given here rather than relying on a generic B-section belt.
Check the drive before ordering. Inspect the sheave grooves for wear, verify that the belt sits correctly in the groove and confirm that all sheaves on the drive are aligned. On a multi-belt drive, replace the full set at the same time so the belts share the load evenly. Cogged classical belts are often chosen where the drive runs over smaller sheaves and needs extra flexibility.
To request a quote, send the part number BX 81, the quantity and any drive details you have. If you are unsure whether this is the correct belt, include a photo of the back marking and the sheave dimensions. We carry Dayco belts and can help confirm the right belt or suggest an equivalent.

Frequently asked questions
- What does the BX profile mean on this Dayco belt?
- BX is the profile of this cogged classical V-belt. It is a raw-edged, molded-cog belt in the BX section, and this listing gives its length as 2133.6 mm.
- How do I confirm that the Dayco BX 81 is the right belt for my drive?
- Read the marking on the belt you are replacing. It should show BX and 81, which matches the 2133.6 mm length listed here. If the marking is gone, measure the old belt and check the sheave groove and alignment before ordering.
- Can I mix this belt with other brands on the same drive?
- We recommend replacing all belts on a multi-belt drive as a set so they are the same type, profile and length. This size is also listed under Stark BX 81, Optibelt BX 81 and Gates BX 81 if you are matching an existing set.
