Belt type 8mm section V-belts
8mm wide · 5mm deep · Optibelt quality
8mm section belts are the largest of the light-duty classical V-belts, sitting just below Z section, and are
used on small machine tools, workshop equipment, small pumps, fans and compressors, food and packaging
machinery, and garden equipment. These belts are made by Optibelt, our premier brand, for smooth, quiet running and long life.
Search by the size on the old belt, or use the filters to narrow it down by length.
Finding the right 8mm belt
Reading the sizeA size like 8 x 500 Li means an 8mm section belt with a 500mm inside length. Some sizes are given as the datum length (Ld) instead, which is a little longer, so check which one your belt shows.
Measuring a small beltIf the size has worn off, wrap a piece of string round the inside of the belt, mark it and measure the string. That gives you the inside length.
Check the sectionMeasure the top width and depth. An 8mm section belt is 8mm wide and 5mm deep. If yours is narrower, see our 5mm or 6mm sections; if it's wider, see Z section at 10mm.
Tip: if a small belt stretches or slips quickly, check the pulleys for wear and the tension. A worn pulley groove will wear out a new belt fast.
