S-670 3-Axis Laser Alignment Systems [DISCONTINUED]

S-670 3-Axis Laser Alignment Systems [DISCONTINUED]

The S-670 Coupling System includes the L-785 Shaft Laser, the T-1285 3-Axis Wireless Coupling Target, mounting brackets, built-in Bluetooth communication, and Couple6 Alignment Software. Alignmnet data is processed in real time and sent via the Bluetooth to the Couple6 software for real time analysis and display.  Alignment corrections can be viewed live as they are made. The laser and target are pre-aligned to the brackets and mount without tools or jigs. Mounting brackets accommodate shafts from 1.5 in. to 6 in. (38.5 mm to 152.4 mm).  Larger sized shafts can be easily accommodated with accessory chains or brackets. With a super linear PSD, the S-670 System offers resolution of 1.0 micron (offset), 0.014 mm/m (angular) and +/- 5 angular range.

L-785 Laser

The L-785 is a low-powered, sealed (IP 67 protection), dual-beam visible light Class II laser. The laser operates on lithium ion battery and lasts 150 hours of continuous operation on a single charge. The laser beam has horizontal centering adjustment, ensuring quick setup. The visible light beam requires no special viewing devices, allowing a quick initial alignment by eye.

T-1285 Target

The battery-operated T-1285 target features a true 3-axis capability that reads both horizontal and vertical center and angle measurements simultaneously. The 3r axis is the rotation sensor (accelerometer) that allows the target to automatically sense starting and stopping points, eliminating the need to use “clock” positions. A sweep angle of as little as 60º allows the system to work in cramped spaces. Target data is processed and sent instantly via Bluetooth to the Couple6 software for real-time analysis and display of misalignment data.

A-970 Bracket Set

These aluminum and stainless-steel dual-post mounting brackets feature quick-set speed nuts for nearly instant set-up and can accommodate shaft diameters from 1”  in. to 6 in. (25.4 mm to 152.4 mm) with standard chainless bracket, and shaft diameters from 5? to 12 in. (127 mm to 305 mm) the with chain attachment. With extra chain links it can accommodate up to 18? (457 mm) of shaft diameter.

It has built-in magnets for shafts with large flanges, such as turbine rotor couplings.

Shaft Alignment

  • Patented Dual-Beam™ Technology that allows the measurement of offset and angle simultaneously with one PSD (sensor), thus eliminating 50% of measurement errors when using 2 sensors.
  • Laser industry’s highest-resolution 2-axis, super-linear PSD sensor, providing 0.5 micron resolution and a measuring area of 33 mm (V) x 13 mm (H).
  • Angular resolution that is 10 times higher than the highest angular tolerance
  • Live 3-axis display in Shim/Move phase
  • Duo-Plane™ Live Move Screen
  • Easy-Guide™ navigation with easy-to-follow, high-quality color screens

" The machine move stage is the most critical step in any alignment. Behind its great graphics, this is where we have seen the very high resolution and accuracy of the system pay real dividends, because the live move data on a Stealth system has proven to be dependable and accurate. I have been very impressed to be able to align a new motor to close tolerances on several occasions with only one alignment measurement, one combined vertical and horizontal live-move correction and a confirmation retest – job done!. Well, you may not always be able to align a machine that fast, but it shows two things: that the condition of the machinery being aligned makes a big difference, and that the Stealth lasers are truly up to the task!
