This Optibelt B 50 belt is a classical V-belt in the VB / HVAC Power series. It has a B profile, a 1346 mm length, a 17 mm top width, an 11 mm height, and a 40 degree angle. Use these dimensions to match the belt you are replacing.
To confirm the B 50 is the correct replacement, read the marking on the back of the old belt. If it shows B 50, the profile and length match. You can also measure the old belt: a B profile has a 17 mm top width and an 11 mm height, and the outside length should be 1346 mm. The 40 degree angle is the included angle of the belt cross-section.
The same size is also listed under Stark B 50. If you need to cross-check, that is the equivalent size to reference. Send the part number, the belt marking, or your measurements to request a quote. Our team can confirm the B 50 or suggest an equivalent based on the data you provide.
