For quick and easy
alignment of sheaves/pulleys

Easy-Laser® D90 is installed in a few seconds, and the laser line that is projected on the targets clearly shows how to adjust the machines.


The tool is attached in a few seconds, and you can easily see the laser line projected on the targets. When the line lies in the slots of the targets, the machine is in the right position. The result is a fast, precise alignment.


Transmissions with two or more belts, or wide belts, are highly affected by misalignment, causing large differences in belt tensions and also increased wear and tear on edges. When aligning with the Easy-Laser® BTA you reduce the wear on sheaves/pulleys, belts, bearings and seals as well as reducing vibration. Increased efficiency also means large energy cost savings.


Easy-Laser® D90 BTA is attached to the side of the sheave/pulley and not to the belt groove. This means it is just as easy to adjust v-belt, flat belt and timing belt pulleys as chain wheels. The clever design of the anchor plate/reference surface ensures hassle-free alignment of both large and small sheaves/pulleys.

Add a digital display unit

Easy-Laser® D90 BTA has targets that are read “visually” and ensure excellent accuracy. That is enough for many users. If, in the future, you want to have a digital display and its associated benefits, you can add the digital detector/display unit (Part No. 12-0791), which can detect the laser line from Easy-Laser® D90 BTA. Full expandability in true Easy-Laser® fashion!
