The Komatsu belt tensioner is made of alloy steel resistant to fatigue and corrosion, capable of handling forces up to 1500 Newtons. Its rotating shaft diameter is 30 millimeters, and the tensioner arm measures 120 millimeters. The internal torsion spring with 250 Newtons per millimeter resistance ensures uniform belt tension under all operational conditions. Wear-resistant bearings with 0.01-millimeter precision provide smooth, noise-free rotation.
The body structure features an aluminum cover with thermal resistance up to 100 degrees Celsius and reinforcing grooves to reduce mechanical stress. The permissible rotation angle of the tensioner is 15 degrees, and the total weight is approximately 3.5 kilograms. Its modular design allows quick replacement without disassembling the engine, while the low-flow internal lubrication system extends bearing life.
