Komatsu belt tensioner

The Komatsu belt tensioner is made of high-strength steel with an anti-corrosion coating and can withstand tensile forces up to 2,500 N. The shaft diameter is 25 millimeters, and the overall body length is 180 millimeters, allowing precise installation on the engine and pulleys. The internal spring is designed with a resistance of 1,200 N, maintaining constant pressure on the belt for up to 15,000 operating hours. Double-sided bearings with initial lubrication can handle rotational speeds up to 4,000 RPM, ensuring smooth movement and reduced friction of the belt. Its ergonomic and reinforced design minimizes vibration and belt wear, extending the overall system lifespan.

The belt tensioner allows both manual and automatic belt pressure adjustment and is compatible with Komatsu diesel and gasoline engines. It weighs 1.8 kilograms, and its quick-mount design facilitates easy replacement and maintenance. The spring and tensioner arm travel up to 25 millimeters, compensating for belt stretch under varying working conditions. Stable performance in ambient temperatures from -20 to 90°C and resistance to vibration and shock maximize system efficiency and belt longevity.
