This Optibelt SPB 4120 belt is a narrow wedge V-belt in the SK S=C Plus series. The SPB profile and 4120 mm length identify the drive position it fits, so you can match it directly to the belt you are replacing.
The SPB profile is a narrow wedge section, and this belt measures 16.3 mm across the top, 13 mm in height, and has a 40° angle. The datum length is 4120 mm. Those four figures are the ones to check against the old belt and the drive sheave grooves before ordering.
Because the profile and length are fixed, the SPB 4120 is selected by reading the marking on the back of the belt or by measuring the old part. If the existing belt is worn or the marking is gone, note the profile, the length, and the top width, and send those details for confirmation.
For a quote, send the part number SPB 4120 and the quantity. If you are replacing more than one belt on the same drive, include the number of belts in the set so the order matches the drive.
