This Mitsuboshi SPZ 612 is a narrow wedge V-belt with an SPZ profile. It measures 9.7 mm across the top, 8 mm in height and has a 40° angle. Use it where a compact, high-capacity drive calls for a narrow cross-section.
Narrow wedge belts like this SPZ 612 are common on industrial drives where space is tight and the pulley grooves are cut for a wedge profile. The 9.7 mm top width and 8 mm height identify the cross-section, while the 40° angle matches the groove angle the belt is designed to run in. Confirm fit by checking the old belt's profile marking and measuring its top width and height before ordering.
The same size is also listed under Optibelt SPZ 612. If your drive uses more than one belt, replace the full set at the same time so the load stays evenly divided. Send the part number, the profile from the back of the belt and the quantity you need by WhatsApp or email, and our team will confirm the right belt or suggest an equivalent.
