Description
MITSUBOSHI B 51 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 B 51 and any equivalents.
The Mitsuboshi B 51 is a classical V-belt built to the B profile. Its 17 mm top width, 11 mm height and 40° angle identify the cross-section, so you can match it to the pulley groove on your drive. The same size is also listed under Stark B 51 and Optibelt B 51.
Use the profile and length as your first check when replacing an existing belt. The B profile sets the fit in the pulley groove, while the 40° angle and 11 mm height confirm the belt's cross-section. If the old belt is worn or the marking is unreadable, measure the top width and height and compare them with these values.
For a quote, send the part number B 51 and the quantity you need. If you are unsure whether this is the correct belt for your drive, include the drive details and a photo of the old belt. The team can help confirm the right belt or suggest an equivalent.
