The SINOCONVE 4L Kevlar V-Belt is designed for lawn and garden machinery that uses clutching, frequent start-stop operation, or repeated reverse flexing. Its confirmed section dimensions are 0.50 inch in top width, 0.31 inch in thickness, and 40° in belt angle.
Aramid/Kevlar cord reinforcement supports high tensile strength, low stretch, and resistance to shock loads. A dry-wrapped special fabric cover helps improve wear resistance and reduce slippage while clutching. The belt is also designed to resist oil, heat, cracking, and repeated flexing. Final length and fitment must be confirmed from the complete belt marking, outside length, sample, or drawing.
The supplied structure reference uses NR/SBR top rubber, buffer rubber, and bottom rubber with a polyester-cotton canvas outside fabric. The Kevlar version uses aramid/Kevlar tensile reinforcement; a polyester-cord construction may also be confirmed for specific orders. Available performance options include static conductivity to ISO 1813 and an operating temperature reference of -55°C to 70°C.
4L is a Kevlar-reinforced lawn and garden V-belt featuring a 0.50 inch top width, 0.31 inch thickness, and 40° belt angle. The aramid tensile cord is intended to control elongation and improve resistance to shock loads in clutching and variable-duty applications. Its dry-wrapped fabric cover provides good resistance to wear and tear while helping limit slippage during engagement. The belt also offers resistance to repeated reverse flexing, oil, heat, and cracking. It is suitable for lawn mowers, garden tractors, tillers, snow blowers, and other outdoor power equipment. Length must be confirmed from the complete marking, outside-length code, sample, or technical drawing.

For light-duty V-belts, the outside-length code may be shown in tenths of an inch. For example, 3L400 indicates approximately 40 inches outside length. The exact marking and length must be confirmed before ordering.
Please provide the complete belt marking, outside length, equipment brand and model, pulley dimensions, clutching method, operating load, quantity, preferred color, old belt sample, or technical drawing. No unverified length range has been added. Final specifications and warranty terms are subject to the order contract.
