Belt alignment visible to the eye

Belt drive alignment

 PAT – the final solution to all your belt alignment needs!

With the PAT, you are never in doubt about whether your belt transmissions are aligned or not. By using the groove as reference, you will achieve a precise alignment which reduces belt wear, bearing failures and vibrations.

Two transmitters with visible red laser line

The PAT comes with two-line laser transmitters, each equipped with two spring-loaded guides that fit into the pulley grooves. The use of two laser transmitters with integrated targets makes it very easy to find out what kind of alignment is required. Parallel offset, angular error, and twist are instantly visible to the operator. Within a few minutes, the operator can determine if the machine requires alignment or not.

Mounting of the transmitters

The PAT units are very easily mounted on the pulleys. The spring action probe finds the center of the belt groove. The industrial built-in magnets snap the units to the pulley in a perfect fit. The PAT is equipped with various-sized removable guides to fit standard sheave sizes A-E (6 mm – 40 mm). Additional guides for the alignment of timing belts are available as accessories.

The alignment process with the PAT

The visible red laser line makes it easy to determine the position of your belt-driven machines.

The alignment process is as easy as the mounting. Just turn on the lasers and look at the opposite mounted unit. The laser draws a line on the target label as in the illustration to the left. If necessary, adjust your machine position until the laser lines are aligned with the center mark on both units.
