Mitsuboshi A81K 4LK830 V-Belt
The A81K / 4LK830 is a high performance Kevlar V belt designed for demanding applications requiring strength, heat resistance, and long service life. Built with aramid fiber cords and a wrapped cover, this belt maintains flexibility under load and resists wear from environmental exposure. It is commonly used in equipment such as lawn tractors, tillers, compressors, and other machinery that runs on a classical A section belt.
This belt is a direct replacement for OEM belts requiring a 1/2 inch top width and 83 inch outside length. The Kevlar reinforcement ensures minimal stretch and consistent power transmission over time, making it suitable for both residential and commercial machines.
