SKF TKSA 51 Shaft Alignment Tool: Flexible, Accurate, and App-Driven Alignment Technology
The SKF TKSA 51 is a modern, app-based shaft alignment tool designed for technicians of all skill levels—from beginners to experienced professionals. Paired with a tablet or smartphone, this tool delivers a powerful balance of flexibility, portability, and precision. Its wide range of included accessories enables efficient alignment on motors, gearboxes, pumps, fans, drives, and many other rotating machines. With built-in training videos and intuitive controls, operators can achieve accurate measurements without specialised training.
Key Features of the SKF TKSA 51
1. Exceptional Measurement Flexibility
The TKSA 51 supports the well-known 9–12–3 measurement method, but adds greater freedom by allowing measurements to begin at any shaft angle. With only 40° minimum rotation required, it is ideal for confined spaces and applications with limited accessibility.
2. Automatic Alignment Reports
After each alignment, the system automatically generates a detailed report. Users can personalise these reports by adding notes, a machine photo, and a digital signature. Reports can then be exported as PDF files and shared directly through mobile apps.
3. Compact Yet Comprehensive
Despite its broad functionality, the tool remains lightweight and compact. Magnetic brackets, extension rods, and chains are included to accommodate diverse machine setups while still keeping the toolkit easy to transport.
4. Intuitive 3D Live View
The 3D live view feature provides real-time visual feedback during alignment. Technicians can rotate the virtual machine model to match the actual equipment, ensuring quick and accurate positioning of measurement heads.
5. Disturbance Compensation for High Accuracy
To maintain precision in environments with vibration or external interference, the TKSA 51 averages measurement values over time. This delivers reliable and stable readings even in challenging industrial settings.
6. Fully Functional Demo Mode
The free mobile app includes a demonstration mode, enabling users to explore the shaft alignment process and interface before purchasing the TKSA 51.
