This Optibelt VB S=C Plus belt is a classical V-belt with a B profile and a 2950 mm length. It measures 17 mm across the top, 11 mm high, with a 40-degree angle. When you need to match the belt being replaced, start with the marking on the old belt and confirm the profile and length.

The most reliable way to match this belt is to read the marking on the back of the belt you are replacing. Look for the profile letter and the length number. If the old belt is worn or the marking is gone, measure the top width and the outside length, then compare those figures to the 17 mm top width and 2950 mm length of this Optibelt belt. The profile B and the 40-degree angle are fixed by the belt construction, so the width and length are the practical checks.

A classical V-belt that has run for a long time may sit lower in the pulley groove, so a used belt can measure narrower than its original size. For that reason, match a new belt to the original specification rather than to a worn sample. If the drive uses more than one belt, replace the full set at the same time so the belts share the load evenly. On a multi-belt drive, mixing a new belt with old ones can leave the new belt carrying more than its share.

Before you install the belt, inspect the pulleys for wear, oil or debris, and check the alignment of the drive. A straight edge across the pulley faces will show whether the sheaves line up. Confirm that the tension is set to the drive manufacturer's recommendation. If you are unsure which belt you need, send the part number, the profile and the length from the old belt, and we can help confirm the right belt or suggest an equivalent.
