Laser shaft alignment tools are precision instruments used to ensure that two or more rotating shafts are properly aligned. Misalignment can lead to increased wear, vibration, and energy loss in machinery, which can result in costly repairs and downtime. These tools use laser beams to measure the alignment of shafts, providing accurate readings that help technicians make necessary adjustments. The process typically involves placing a laser transmitter on one shaft and a receiver on the other. The tool then calculates the alignment by measuring the distance and angle between the shafts. This technology is widely used in various industries, including manufacturing, energy, and automotive.
