Launched in 2007, Hamar Laser’s Stealth Series™ of laser shaft alignment systems set a new benchmark for precision, performance, and usability in industrial alignment tools. The series began with the S-680, a robust, high-end system featuring our advanced Dual-Beam™ technology and a rugged, fully sealed housing built to endure harsh industrial environments. It was designed to deliver exceptional accuracy, especially in long-distance and demanding alignment applications, and quickly became a flagship solution for facilities requiring top-tier performance.
Later that same year, Stealth Series™ introduced the S-670, a unique hybrid system that brought together the best of both worlds. The new S-670 adopted the form factor of the S-680, including its rugged dual-beam architecture, while being the first 3-axis sensor technology of the Stealth Series™ brand. This hybrid approach delivered advanced capabilities at a more accessible price point, allowing users to benefit from a powerful system without stepping all the way up to the 5-axis platform. Its compatibility with advanced software applications and accessories made it a versatile choice of facilities with a mix of alignment needs.
Completing the lineup in 2009, the S-660 introduced a streamlined, 3-axis platform that made laser alignment more accessible without sacrificing precision. Perfect for routine alignments and general-purpose machinery, the S-660 was compact, easy to use, and fast, making it ideal for facilities looking to improve alignment processes with minimal training. Together, the S-680, S-670, and S-660 formed the perfect trio of shaft alignment systems, delivering scalable performance and future-ready technology across every tier of industrial maintenance.
Together, the Stealth Series represents more than a decade of commitment to engineering excellence, setting the stage for the even more powerful and flexible X-Series™ systems that followed.
As technology and alignment standards continued to evolve, so did the capabilities of the Stealth Series™. Each system was designed with upgradeability in mind, allowing users to extend the value of their investment over time. As the most compact and accessible system in the Stealth Series™, the S-660 was built with simplicity and efficiency in mind, but without compromising the core performance needed for precision shaft alignment. Its 3-axis technology provided accurate, real-time feedback, while its compatibility with key software applications and hardware accessories ensured long-term versatility. Designed as an entry-level solution, the S-660 offered an ideal starting point for plants looking to modernize their alignment practices, with upgrade options that allowed it to grow alongside evolving maintenance needs.
Positioned as the mid-tier solution in the Stealth Series™, the S-670 was engineered to deliver the perfect balance between performance and flexibility. It combined the advanced 3-axis measurement technology of the S-660 with the dual-beam form factor of the high-end S-680, giving users powerful alignment capabilities in a more compact package. Fully compatible with X-Series™ software apps and hardware accessories, including Machine Train and Geometric applications, the S-670 stands out for its long-term adaptability. Most notably, it offers a full upgrade path to the 5-axis X-880 system, allowing users to scale into more advanced diagnostics and complex alignments without having to replace their entire platform.
As the original powerhouse of the Stealth Series™, the S-680 set the standard for high-performance laser shaft alignment when it launched in 2007. Designed with advanced 5-axis Dual-Beam™ technology, it provided unmatched angular and offset measurement accuracy across both horizontal and vertical planes. Its rugged design, precision sensors, and comprehensive feature set made it ideal for demanding industrial environments and complex machine configurations. Fully compatible with the latest X-Series™ software apps and hardware accessories, the S-680 remains a powerful and relevant platform today. And because it shares the same core architecture as the X-880, no upgrade is necessary, users already have access to Hamar Laser’s most advanced 5-axis capabilities right out of the box.
Assumptions for this example: You have a 480 volt motor drawing 40 amps and operating 8400 hours/year. The Power Factor is .85. Electricity costs $0.06/kWhr. Also assume that the amp draw is measured before and after the alignment and it is found that there is a 1 amp difference.
kW =V* A*PF*1.732/1000
kW =480V* 1A*.85*1.732/1000
kW =.706 = power savings
Savings ($) = operating hours * kW savings * kW cost
Savings ($) = 8400 * .706 * $0.06/kWhr
Savings ($) = 8400 * .706 * $0.06/kWhr
Savings ($) = 355.82
If your plant has 80 similar motors, and if only half of them had the same amount of savings, it would total $355.82 * .5 = $14,232!
The coupling icons next to the data displays show the direction of the misalignment at the coupling and update as you move or shim the motor! You can also zoom in on the coupling to show them in the live display area of the screen.
