Bearing Surface Flatness

Checking the flatness of large bearings surfaces during in-situ machining can be time consuming and difficult, especially if they are vertical. Fortunately, our laser alignment systems handle these kinds of alignment checks with ease and can help to speed up the job and improve accuracy.

L-740 Ultra-Precision Leveling Laser Alignment System

Over 50 years of alignment experience went into the design of the L-740 Ultra-Precision Leveling Laser Alignment System, featuring an automatically rotating laser plane with a long operating range and the highest accuracy in the industry for fast and easy alignment data taking:

  • Combining a continuously sweeping laser plane with large measuring-range sensors and wireless communication helps the L-740 to take bearing flatness data in record time.
  • Precision laser planes have a flatness measuring capability of 0.5 arc second (.00003 in/ft or 0.0025 mm/m).
  • Two methods to check flatness:
    1. Use our built-in 2 arc second level vials (or 1 arc second split-prism option) to level the laser and check the surface for flatness relative to a level earth plane.
    2. Use 3 reference points on the surface and check the rest of the surface for deviation from the reference datum plane.
  • PDA or PC data displays can show multiple target sensors at the same time
    • Allows multiple points to be checked for flatness at the same time
    • Speeds up alignment checks and reducing costs.
  • If realignment is needed, real-time data automatically updates the flatness data as adjustments are made.
  • Wireless targets can be used up to 150 ft (46 m) from the laser. Powerful Windows-based Plane5 Flatness Software makes collecting and analyzing bearing flatness data fast and easy.
