PVC SLEEVE PU sleeve STRAIGHTENED ROLLERS / ROLLER LENGTHS Lagging GENERAL TECHNICAL INFORMATION
●During the inspection, the concentric precision of each roller is measured. If the concentric precision falls outside the specified tolerance (page 28), the tube is straightened. The concentric deviation is corrected only if it falls outside the tolerance.
●When measuring the concentric precision and also for the straightening process, the tube is the reference point. The concentricity between shaft and tube is not checked.
●The PVC sleeve ensures a particularly high noise reduction and offers a high level of protection for sensitive materials. An improved conveyance of materials is achieved with the higher coefficient of friction compared with a steel tube. Materials can easily be separated since the larger diameter leads to a higher speed with the same rotational speed.
●The PU sleeve ensures a high level of noise reduction, particularly for steel containers, and offers a high level of protection of sensitive materials. An improved conveyance of materials is achieved with the higher coefficient of friction compared with a steel tube. Materials can easily be separated since the larger diameter leads to a higher speed with the same rotational speed. With mechanical stress, e.g. with abrasion, it offers a higher robustness than a PVC sleeve.
●The lagging ensures a high level of noise reduction and offers a high protection of medium-heavy to heavy materials. An improved conveyance of materials is achieved with the higher coefficient of friction compared with a steel tube. Materials can easily be separated since the larger diameter leads to a higher speed with the same rotational speed. The lagging offers a high robustness under mechanical stress and is very abrasion-proof. Compared to sleeves, that are not connected to the tube, axial forces are also allowed.
