However, it is not only laser optical alignment or tension testing that are often among the basic criteria for gentle operation when installing belts. Particularly in systems that have been in use for a long time, where parts are replaced based on maintenance intervals, the following should not be underestimated, for example ...

... assessment of the condition of the belt pulleys... permissible shaft misalignment angular or parallel... the influence of vibration-damping elements ... tightening torques for Taperlock connections ... where necessary, checking the belt profile/type ... Set equality/age of the components to be replaced ... extraordinary operating conditions... external influences (light, temperature, vapors, Ex zone) ...

determination of the optimum bearing arrangement... correct mounting of the bearing... where necessary, adjustment of the bearing clearance... optimum relubrication of the bearings...

what is optimized over the service life of the system ... etc.
