The Optibelt SPB 4000 is a narrow wedge V-belt in the SK metric profile series, with an SPB profile and a 4000 mm length. Before you fit it, inspect the drive and sheaves so the new belt runs true and wears evenly. We carry this belt and can help confirm it for your application.
A narrow wedge V-belt like this one seats deeper in the groove than a classic V-belt, so sheave condition matters. Check groove wear, cracks, corrosion and any burrs that could cut the belt. Confirm that the sheaves are aligned and that the belt sits at the correct height in the groove.
The SPB profile has a 16.3 mm top width, 13 mm height and a 40 degree angle. The 4000 mm length is the datum length. If the old belt is stretched or worn, measure the drive and compare against the markings on the back of the old belt before ordering.
The same size is also listed under Mitsuboshi SPB 4000 and Stark SPB 4000. For a quote, send the part number, the quantity and any details from the old belt. We reply promptly and can help confirm the right belt.
