Extending service life thanks to correct alignment is easy. Large savings can also be made when it comes to the cost of these types of belts and pulleys. Whichever  tool you choose for sheave/pulley alignment, it usually pays for itself within a few months.
 
The advantages of laser compared to traditional technology

Using lasers makes alignment faster and easier than with traditional methods such as rulers and cords. These methods usually require two people to carry out the work, one to hold the ruler and one to adjust the machine. Spotting small differences with the naked eye using traditional methods is both arbitrary and subjective. Laser measurement systems are considerably easier to read and are much more accurate. From the belt manufacturer’s side, it is sometimes recommended that there is a maximum angular error between the pulleys of 0.5 to 0.25 degrees for optimal service life and efficiency. Such small angles cannot be seen with the naked eye without the assistance of a laser.

Correctly aligned machines means greater improvements

·         Increased availability and productivity of the machine = assured production

·         Increased service life of belts, pulleys and bearings = fewer removals of replacement parts

·         Optimally utilized lubricant film = less risk of overheating and secondary damage

·         Reduced friction = lower energy consumption

·         Less vibration = reduced noise level

·         Less risk of serious breakdowns = safer working environment

·         Greater overall savings with fewer spare parts, lower energy consumption and less unscheduled downtime.
