Deflection and breaking force
The deflection provides information about the manufacturing quality. When comparing the measurements on each side, a small difference in deflection values is ideal. If the deflection of a saw chain differs greatly from one side to the other, this is a sign of poor-quality riveting. Chains with this type of riveting can break after prolonged use as the tensile forces act at different levels on each side. The guide bar is also subjected to high levels of wear with poor-quality riveting of this kind. The chains from GRANIT and the original equipment manufacturer boast the best riveting with a difference of just 2 mm between sides. With a difference of up to 17 mm, the manufacturing quality of the products from other manufacturers is significantly impaired. The breaking force provides information about the durability of the chain in the event of sudden overloading, for example in the event that the saw chain jams. The higher the breaking force, the better. With a breaking force of 8.3 kN, the GRANIT Endurance Cut saw chains are among the top performers. The excellent results in the deflection and breaking load tests show that GRANIT saw chains are able to withstand very high breaking loads even after prolonged use.
