Mitsuboshi A18K 4LK200 V-Belt

The A19K / 4LK210 is a high performance Kevlar V belt designed for compact drive systems that require strength, flexibility, and resistance to heat and wear. Built with aramid fiber cords and a durable wrapped cover, this belt delivers long-lasting performance in small engine applications, garden equipment, and machinery operating on a classical A section pulley system.

This belt is a direct replacement for OEM belts requiring a 1/2 inch top width and 21 inch outside length. The Kevlar cord construction minimizes stretch under tension and ensures consistent power transfer, making it a reliable option for residential and light commercial use.
