Aids the alignment of belt drives

Optibelt recommends the handy and precise optibelt LASER POINTER II for aligning drives. Alignment is easier because it is not necessary to hold a levelling cord, and the powerful and bright laser beam is visible on the silver target magnets. The assembly engineer can also perform alignment quicker and more accurately. Less friction means less wear on pulleys and belts, longer running times and so fewer downtimes.

Reduction in spare parts costs. In the case of several or large drives, the use of the
optibelt LASER POINTER II usually pays off within the first month of purchase.
