Key Features of the SKF TKSA 31

Here are the core features of the SKF TKSA 31 shaft alignment tool, which highlight its intuitive operation, affordable design, automatic measurement capabilities, built-in reporting, and comprehensive machine library:

• Easy 3-Position Measurement: Uses the well-known 9-12-3 o’clock measurement method with additional positioning flexibility, requiring a minimum rotation of only 140° — suitable for applications with limited rotational access.
• Automatic Measurement: Enables hands-free operation by automatically detecting the position of the measuring heads and capturing data only when they are correctly positioned.
• Live View Correction: Provides real-time vertical and horizontal correction values on the touchscreen display, supporting intuitive adjustments and facilitating precise machine position corrections.
• Automatic PDF Reports: Generates alignment reports after each measurement, which can be customised with application notes and easily exported as PDF files for documentation.
• Machine Library: Built-in library stores all machines and alignment reports, simplifying machine identification and streamlining the alignment workflow across multiple assets.
• Soft Foot Detection: Embedded soft foot tool helps identify and correct soft foot conditions before alignment, ensuring a stable foundation for accurate results.
• Affordable & Budget-Friendly: Focuses on the standard shaft alignment process and essential functions, making professional laser shaft alignment accessible for almost every budget.
