MITSUBOSHI A 81 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 A 81 and any equivalents.
The Mitsuboshi A 81 is a classical V-belt with an A profile. Its 13 mm top width, 8 mm height and 40° angle identify the cross-section, while the A 81 part number covers the length. This page gives maintenance, engineering and purchasing teams the key dimensions to match an existing drive belt.
The A profile is a familiar classical V-belt section. With a 13 mm top width and 8 mm height, it fits pulleys machined for A-section belts. The 40° angle is the included angle of the belt cross-section, so it seats correctly in the pulley groove when the drive is properly aligned and tensioned.
The A 81 part number is the reference to use when checking a replacement. The same size is also listed under Stark A 81 and Optibelt A 81, so you can compare markings if the old belt is worn or the label is unreadable. Always confirm the profile and the part number before ordering.
For a quote, send the part number A 81 and the quantity you need. If you are unsure whether this is the right belt for your drive, include a photo of the belt back and the pulley groove so our team can help confirm the profile or suggest an equivalent.
