T-1220 2-Axis Bore Target with See-Through Capability 20×20 mm PSD

Large-bore, see-through target for long-distance bore applications such as stern tube and shaft bearing alignments on large ships. Has large measuring range with its 20×20 mm super-linear sensor. Up to 1 micron resolution and <1% measurement error. Prism flips out of the way to allow the laser to pass through to other targets without having to remove the target.

  • Stern tube bores
  • Long-distance applications where the L-708LD Laser is used
  • General alignment of large bores where a big misalignment is expected
  • Cam/Crankshaft/Cylinder Bore Alignment/Inspection
  • Turbine Bores
  • Straightness checks on bores from 6 in. (152.4 mm) to 40 in. (1 m)
  • .0001 in. (0.001 mm) resolution and < 1% linearity when used with R-1307 Readout
  • PSD size of .79x.79 in. (20×20 mm)
  • PSD centered to measuring feet to within .0005 in. (0.012 mm)
  • Prism flips out of the way to allow the laser to pass through to other targets without having to remove the target.
  • Supports L-708LD Long-Distance laser as well as L-705/L-706 Bore Lasers and L-700 Spindle Laser.
  • Use the T-1225L Large-Bore 3-Leg Adapter for most applications from 4 in. (101.6 mm) to 40 in. (1 m)
