V-belt Gates BB51

GATES BB51 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 BB51 and any equivalents.

The Gates BB51 is a double-V (hexagonal) belt in the Hi-Power Dubl-V series with a BB profile and a length of 1370 mm. It is built for drives that use both sides of the belt. The same size is also listed under Dayco BB51.

Before fitting, inspect the drive and sheaves. Check sheave grooves for wear, rust, or debris that can shorten belt life. Confirm that the sheaves are aligned and that the belt tensioning system moves freely. A double-V belt contacts both sides, so both sets of grooves must be in good condition.

Verify the part number on the old belt and match it to the BB profile and 1370 mm length. If the drive uses multiple belts, replace them as a set so the load is shared evenly. Keep the sheaves clean and check that the belt sits correctly in the grooves.

To request a quote, send the part number BB51 and the quantity you need by WhatsApp or email. If you are unsure whether this is the right belt for your drive, include the profile and length from the old belt and our team will confirm it or suggest an equivalent.
