This Optibelt SPZ 3550 is a narrow wedge V-belt in the SK metric profile series. It measures 3550 mm in length, with a 9.7 mm top width, 8 mm height and a 40° angle. Before fitting it, inspect the drive and sheaves so the new belt runs true from the start.
Check sheave grooves for wear, scoring, or embedded debris, and confirm the grooves match the SPZ profile. Misaligned or worn sheaves can shorten belt life and cause vibration even when the belt itself is correct. Verify that the sheave diameters and the center distance suit a 3550 mm belt before installation.
The same size is also listed under Mitsuboshi SPZ 3550 and Gates SPZ 3550. If you are matching an existing belt, read the marking on the back and compare the profile and length against this Optibelt SPZ 3550. Send the part number, quantity, and any drive details by WhatsApp or email to request a quote.
When replacing belts on a multi-belt drive, fit a full set of the same size and profile so the load is shared evenly. Keep the sheaves clean and free of oil or dust, and tension the belt according to the drive manufacturer's specification. After the first run-in period, recheck tension and alignment.
