The Dayco BX 46 is a cogged classical V-belt in the BX profile with a length of 1244.6 mm. The raw-edged, cogged construction is common on industrial drives where standard classical V-belts are specified. This page covers where this type of belt is used and how to confirm it fits your drive.

Cogged classical V-belts like the BX 46 are used on drives that run at higher speeds or over smaller pulleys than a wrapped belt handles well. The cogged underside improves flexibility and heat dissipation, which suits equipment such as fans, pumps, compressors, and general line-shaft drives. The BX profile is a classical cross-section, not a narrow wedge or a serpentine belt, so it will only seat correctly in a BX-profile pulley groove.

To confirm fit, read the marking on the back of the old belt and compare it to the BX 46. Check that the profile is BX and that the length matches 1244.6 mm. Inspect the pulley grooves for wear, oil, or debris, and check alignment and tension. If the drive uses multiple belts, replace the full set at the same time so the load stays evenly distributed. The same size is also listed under Stark BX 46 and Optibelt BX 46, which may help if you are matching an existing installation.

When you request a quote, send the part number BX 46 along with the profile and length from the old belt if it is still readable. If the marking is worn, send photos of the belt and the pulley grooves, plus the drive make and model. The team can help confirm the right belt or suggest an equivalent.
