Application: Laser Sheave / Pulley Alignment
Large savings to be made with correctly aligned machines
- A common misunderstanding is that sheave/pulleys are not affected dramatically by misalignments. This assumption means that the industry has unnecessarily high electricity costs. Several investigations have shown savings up to 10 % in energy costs alone!

Transmissions with several wide belts are especially sensitive. It is easy to understand that the difference in belt tension between the inner and outer belts can differ greatly when aligned incorrectly. This reduces efficiency as not all belts are driven optimally. If one belt is worn then all belts must be replaced with new ones at the same time, which adds expense to the entire operation. Even wide belts are affected more as the tension is uneven over the entire width.
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 of our tools 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 work 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 these methods is both arbitrary and dependent on who is performing the alignment. Laser measurement systems are considerably easier to read. In addition, they 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 utilised 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.
