Correct alignment of the shaft is important in order to achieve high efficiency and reliability of rotating machinery, such as motors, pumps, ventilators, fans and compressors. Schaeffler offers the new FAG Top-Laser EQUILIGN. This can be used to carry out laser optical alignment. Thanks to its robust design and useful functions, the handy device is ideally suited to use in maintenance. The device guides the user step by step through the measurement procedure up to determination of the correct alignment status. In addition to high plant availability, good alignment also makes a considerable contribution to reducing energy and costs. It is of a watertight and contamination-resistant construction specially for these sometimes rough ambient conditions and is ready for operation permanently and anywhere by means of batteries or rechargeable batteries. In poor light conditions, an integral light metere ensures that the screen brightness adapts automatically to the environment. The TFT display thus remains well visible at all times. With a mass of 800 gram and compact dimensions, the precision measuring device can be carried comfortably and the screen can be operated using both thumbs.
