pumps, fans and air handling units, machine tools, and agricultural and construction machinery. We stock B
section belts from several leading manufacturers, so you can choose the right balance of performance and

Finding the right B section belt
Reading the codeB54 means a B section belt with a 54 inch inside length (1372mm). Metric sizes may show the inside length (Li) or the datum length (Ld), which on B section is 40mm longer, so check which your belt uses.
Which brand?Every belt here fits the same B section pulleys. Choose Optibelt for the longest life on hard-working or continuous drives, or a value brand for occasional-use machinery.
Is it really B section?A B section belt is 17mm wide and 11mm deep. An SPB wedge belt is a similar width but deeper, at 13mm, and light-duty 5L garden belts are a different construction.
Tip: on drives with two or more belts, replace them all at once with a matched set of the same brand. For small pulleys or hot-running drives, a cogged BX belt of the same length is a straight upgrade.
