With two wireless measurement units, large sized detectors and powerful lasers, the instrument performs precise measurements in even the most challenging conditions. The ergonomic display unit with intuitive touch screen navigation makes your alignments fast and easy, whilst innovative features, like the “free measurement”, increase the alignment performance. With the focus on improving alignment practices, the SKF Shaft Alignment Tool, TKSA 41, is one of the industry’s best value alignment solutions. - Wireless communication improves instrument handling and allows alignment of difficult to reach applications from a safe position.- Free measurement allows alignment measurements to start at any angle and finish with an angular sweep of just 90°.- Automatic measurement enables hands-free measurements by detecting the head position and taking a measurement when the heads are rotated into the right position.- Automatic reports are generated after each alignment. The reports can be customised with notes and pictures from the built-in camera for the most comprehensive overview. All reports can be exported as pdf files.- Live view supports intuitive measurements and facilitates horizontal and vertical alignments (NOT vertical shaft alignment. See TKSA 51 or TKSA 71 for that functionality).- Machine library gives an overview of all machines and alignment reports. QR codes can be used to further simplify machine identification and improve the alignment workflowRecommended for almost every industryShaft alignment is recommended for almost every industry, as it enables machine uptime to be significantly improved and maintenance costs to be reduced. The simplicity of the TKSA 41 provides greater confidence for the performance of alignment tasks on all types of horizontal rotating machines.Specifications:- Sensors and communication : 29 mm (1.1 in.)

In 1993, Marshall Space Flight Center awarded AVCON a contract to fabricate a set of magnetic bearings, install them in a fixture representing a Space Shuttle Main Engine turbopump, and test them under simulated Shuttle mission conditions. Those tests are under way.

Among companies producing advanced magnetic bearing systems for industrial use is AVCON, Inc., Agoura Hills, California. AVCON offers a unique technological approach that evolved from the company's work on contracts with Lewis Research Center, and Marshall Space Flight Center. The technology developed in the NASA programs contributed to AVCON's ability to overcome the limitations of early magnetic bearing systems, namely large size and weight, high power consumption and cost. The company's product line embraces a family of very compact, lightweight, power efficient, low cost bearing systems.

Magnetic bearing vs ball bearing

Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion without friction or wear. Long considered a promising advancement, they are now moving beyond promise into actual service in such industrial applications as electric power generation, petroleum refining, machine tool operation and natural gas pipelines.

AVCON worked initially with Lewis on development of a magnetic bearing system for a Cryogenic Magnetic Bearing Test Facility. The resulting AVCON development was extensively tested over a two year span and these tests provided a wealth of data on the performance of magnetic bearings under severe conditions. In this program, AVCON developed the basic hybrid magnetic bearing approach that characterizes its commercial products, an approach in which both permanent magnets and electromagnets are employed to suspend a shaft; the permanent magnets provide suspension, the electromagnets provide control. Analyses of AVCON bearing tests showed that a hybrid magnetic bearing was typically only one-third the weight, substantially smaller and dramatically less power-demanding than previous generations of magnetic bearings.

The technological base afforded by AVCON's NASA work, buttressed by additional R&D sponsored by the U.S. Air Force and a major turbine engine manufacturer, enabled AVCON to develop a unique "homopolar" approach to permanent magnet type bearings that, the company says, are significantly smaller than prior designs; additionally, their control electronics are a fraction of the weight of previous systems and power consumption is much lower than in all-electromagnetic designs. Among other advantages cited are virtually zero friction and therefore no lubricant requirement; no wear, no vibration; longer service life; and very high reliability because single point failure modes are eliminated.
