The Optibelt SPB 3800 is a narrow wedge V-belt in the SK S=C Plus series. It carries an SPB profile, a 3800 mm length, a 16.3 mm top width, a 13 mm height and a 40 degree angle. MR Industrial Accessories supplies this belt to maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America.

The fastest way to identify the belt on your drive is to read the marking on its back. A worn belt often keeps its printed code long after the label on the machine has faded, so the back of the belt is usually the most reliable record you have. Look for the profile and the length together, then match them against this page. On this belt the marking reads SPB 3800, which tells you the profile is SPB and the length is 3800 mm.

A narrow wedge V-belt like this one sits in a groove cut for the SPB profile, and the 40 degree angle and 16.3 mm top width are what let it seat correctly. If the old belt has stretched, hardened or worn down, the marking is still the starting point for the replacement. Measure the length only as a check against the printed code, not as a substitute for it.

Send us the part number from the belt, along with the quantity you need and any details about the drive it runs on. Our team replies promptly by WhatsApp or email and can confirm the SPB 3800 or suggest an equivalent. If you are replacing more than one belt on the same drive, include the full set so we can quote them together.
