Description
OPTIBELT AX 21 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 AX 21 and any equivalents.
This Optibelt Super TX AX 21 is a cogged classical V-belt with an AX profile and a length of 584 mm. We carry it for maintenance, engineering and purchasing teams who need a defined part number rather than a guess at the counter.
The most useful quote request is short and specific. Send the part number AX 21, the Optibelt Super TX series name, and the profile and length you see on the belt: AX and 584 mm. If you are matching an old belt, include a photo of the back marking and the worn profile so we can confirm what you are replacing.
The same size is also listed under Dayco AX 21. If your drive currently runs that reference, tell us so we can compare the two listings against your application. For drives with more than one belt, list the quantity and note whether you are replacing the full set.
If the marking on your old belt is unreadable, send the drive details instead: sheave groove profile, the measured outside length, and the equipment or drive it runs on. We will check the Optibelt Super TX AX 21 against what you describe and reply with the correct part number.
