High-strength chain PHC series

Using tensile strength as the measure of a quality chain does not always provide a complete picture. While tensile strength is important to use in calculating the maximum chain pull, useful in lifting calculations, this does not always represent the fatigue life and performance of the chain. The pattern of the work load is particularly complex in heavy drive environments where significant shock loads are present. This can lead to rapid elongation and chain failure. Therefore the SKF Xtra Strength Chain design includes, optimized hardness of the material, precision fit of the components as well as an overall size increase of the parts. This will in turn provide a much longer service life for the chain in demanding drive conditions.
