https://www.optibelt.com/en/products/rubber-timing-belts/optibelt-omega-hl/ On drives with a low belt speed, optibelt OMEGA HL timing belts surpass the capacity of optibelt OMEGA HP by up to 15%. In addition, the design was optimised so that optibelt OMEGA HL is much more suitable for shock loaded drives with extreme fluctuating loads.
