Easy-Laser® XT770 Shaft Alignment System

Easy-Laser® XT770 is the most powerful of our Generation XT shaft alignment systems. The 360° Live feature gives you even more possibilities to perform advanced adjustments.

With Easy-Laser XT770 shaft alignment system you can perform shaft alignment of horizontal and vertically/flange mounted machines, but also align machine trains, measure twist of foundation, soft foot, bearing clearance, and more. The EasyTrend program allows you to keep track of machine movement over time. That is useful when checking for thermal expansion and pipe strain issues for example.

2 axis PSDs (position sensitive detectors) permit adjustment of your machine both vertically and horizontally at the same time, with measuring units in any position. We call it 360° Live adjustment. With the XT770 shaft alignment system, you have a choice of several different measurement methods, e.g. continuous sweep and multipoint. This gives you the flexibility you need to achieve the perfect measurement result.

Easy-Laser XT measuring units and display unit are shockproof and rated both IP66 and IP67 water and dust proof. Along with long operating times, this guarantees you will be able to take on and finish even the toughest jobs.
