D90 - Belt alignment

The D90 belt alignment 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.


Large cost savings

Transmissions with two or more belts, or wide belts, are highly affected by misalignment, causing large differences in belt tensions as well as 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.

For all types of sheaves/pulleys

Easy-Laser® D90 BTA is attached to the sheave/pulley side 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 anchor plate/reference surface's clever design 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 you want to have a digital display and its associated benefits in the future, you can add the digital detector/display unit (Part No. 12-1054), which can detect the laser line from Easy-Laser® D90 BTA. Full expandability in true Easy-Laser fashion!
