How To Calculate Belt Tension

proper belt tensioning

How you tension a belt at installation will determine how long the belt will run. Too little tension results in slippage, excess heat, and premature belt & pulley wear. Too much tension results in excessive stress on belts, bearings, and shafts. However, there is still a wide range of tension which a belt will operate satisfactorily.
