UNIVERSAL BELT For: gardening machines (lawn tractors, lawn mowers, etc.) for flat engine or self-propelled engine. Features: External development inches: 22" External development mm: 559 mm Section equivalent: Z20 CODE : 3L220 ALSO : The structure is characterized by a special low friction fabric, aramid ropes, chloroprene rubber compound reinforced with cloth. The 3L, 4L and 5L banded belts are designed and manufactured specifically for machines with friction coupling and where the transmission system includes an external belt tensioner. The outer fabric ensures a silent engagement of the friction joint and increases resistance to wear and heat. Aramid ropes offer high tensile strength, no elongation and high resistance to sudden loads. R OFL EX G AR DEN
