http://bit.ly/2VG6Obb The XT190 is a wireless, digital tool for alignment of belt drives. with the Easy-Laser® XT190 you reduce the wear on sheaves and pulleys, belts, bearings, and seals, and you also reduce vibration. Easy-Laser® uses the pulley’s side surface as a reference during alignment. This gives greater accuracy, as the contact surface for the tool is larger than if the tool was mounted against the radial surface. The XT190 can be used for all types of sheaves/pulleys, such as v-belt, timing belt, flat belt and chain drives. #laseralignment #beltalignment #easylaser
