D92 – Belt alignment

Easy-Laser® D92 BTA is the perfect tool for sheave and pulley alignment. Mounted in a few seconds, the laser line projected onto the targets allows you to quickly ascertain and correct the misalignment. It couldn’t be easier!

The D92 belt alignment tool is attached to the sheave 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 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.

For all types of sheaves/pulleys

Easy-Laser® D92 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® D92 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. 12-1054), which can detect the laser line from Easy-Laser® D92 BTA. Full expandability in true Easy-Laser fashion!
