Timing Belts and Pulleys
Reliance timing belts and timing pulleys are available in 2.5 mm and 5 mm pitch. High tensile stainless steel reinforced polyurethane belts with widths of 6 mm, 10 mm and 16 mm, coupled with aluminium alloy machine cut pulleys, provide cost effective motion over extended centres.
