tensile resistance wear resistance fatigue resistance corrosion resistance lightness/efficiency FATIGUE RESISTANCE : During use, a chain is subjected to alternate stresses. It is tightened on the upper strand, loosened after engagement on the drive pinion, then tightened again on the rear sprocket. It is also subject to acceleration and deceleration controlled by the rider and to torque changes on uneven terrain. The same applies as in the case of tensile resistance, i.e. the choice of steel and the quality of the heat treatment are essential factors responsible for determining fatigue resistance. In addition, all SEDIS motorbike chains undergo shot peening to increase their fatigue resistance even further. |
