Putting It Together
Assembly Tolerances Overall length tolerances required for cable assemblies and cut lengths of cable often dictate the production method to be used and thus the cost. Close tolerances frequently result in higher costs for both production and quality assurance. The allowable tolerance and inspection methods should be reviewed and agreed upon with Bergen prior to production.
When specifying assembly length, best practice will be to use distance between designated measuring points as shown in the different sections. Measuring points are normally located at the load bearing points of fittings.
Conduit Length Tolerances Overall conduit length tolerances are listed below. The acceptable tolerance and inspection method should be reviewed with Bergen prior to production.
Breaking Strength Safety Factor In determining the working load of a cable or wire rope, the direct stress plus the shock in bending loads must be considered. To assure long life, a reasonable safety factor should be applied to the working load. Standard industry practice is a 5:1 safety factor for many applications. Higher safety factors are used under certain conditions such as extreme shock loads, aircraft control cables, etc.
