A common misunderstanding is that sheave/pulleys are not significantly affected by misalignments. This assumption means that the industry has unnecessarily high electricity bills. Several studies have shown that proper alignment can lead to savings of up to 10% in energy costs alone!
Extending service life thanks to correct alignment is easy. And whichever of our tools you choose for belt alignment it usually pays for itself within a few months.
Easy-Laser belt alignment systems XT190 and D90 uses the pulley’s side surface as 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. Also, any faults and damage on the pulley affect the result less on the side. The risk of wear and damage on the pulley is obviously greater in and by the groove where belts run. A further advantage is that without extra accessories, all types of pulleys can be aligned, regardless of belt type. It is even easy to compensate for pulleys of varying widths. Magnetic mountings on lasers, detectors or targets make it easy to install the equipment. Even non-magnetic pulleys can be aligned as the units are extremely light and can be mounted against the side, secured by double-sided tape.
For small and large pulleys (A/B). A large mounting surface (C) as on the XT190 or D90 affects accuracy less than a small one with the same fault on the pulley.
