A new handheld laser optical alignment device has been launched that enables faster, easier alignment of shafts in rotating equipment such as fans, motors, pumps, gearboxes, ventilators and compressors.



On show for the first time in the UK at MAINTEC 2013, Schaeffler’s FAG Top-Laser EQUILIGN is a compact, robust, easy-to-use device that guides the user step-by-step through the measurement process until correct shaft alignment is achieved. Graphical operating instructions and an intuitive autoflow function ensure that all maintenance technicians can use the device, regardless of their skills or experience.

The correct alignment of coupled and uncoupled shafts is critical in order to achieve high efficiency and reliability of rotating equipment. Approximately 20% of rotating equipment is incorrectly aligned. A correctly aligned shaft means less friction and vibration are generated by the drive system, which means less wear on belts, pulleys, bearings and seals. This means the running time and reliability of rotating machinery is increased, energy costs are kept to a minimum and overall plant efficiency is improved.

FAG Top-Laser EQUILIGN is waterproof and contamination-resistant (protected to IP65), which means plant and maintenance engineers can use the device in harsh industrial environments. The device is powered by batteries or rechargeable batteries and so is ready-to-use at all times. Even in poor light conditions, an integral light meter automatically adapts the brightness of the display to suit the environment. The device is compact and easy to carry, weighing just 800g. An ergonomic design also allows the user to operate the device using both thumbs.

FAG Top-Laser EQUILIGN benefits from a reliable real time display that indicates any horizontal or vertical movements during alignment. Up to 50 measurement files can be stored directly on the device. Even if operation is interrupted, the measurement data is automatically secured and the process can be continued later without any problems.

Measurement data can be output in metric or imperial units. Users can also select from 20 available languages, including Russian and Chinese. The device is supplied with a practical carry case and a range of accessories including mounting brackets, reflector, chains, posts and batteries.

In addition, a set of 360 shims (20 shims in three sizes and six thicknesses) and a withdrawal tool is available for eliminating vertical misalignment and ‘soft foot’. An Accessory Kit is also available for larger shaft diameters or coupling heights, which includes various sizes of posts and chains, as well as magnetic holders.
