A-516-II Self-Centering, 2-Axis Target 20×20 mm with Roller-Bearing Measuring Feet

A-516-II Self-Centering, 2-Axis Target 20×20 mm with Roller-Bearing Measuring Feet

Description

The A-516-II Target is a 2-axis, self-centering target with wheeled measuring tips, designed for deep-bore, large-diameter bore straightness applications, such as gun barrels and hydraulic cylinders. For bores using the roller tips, the A-516-II can accommodate bores from Ø3.90 in. (Ø99.1 mm) to Ø29.5 in. (Ø750.0 mm).  For bores using non-roller tips, the A-516-II can accommodate bores from Ø2.68 in. (Ø68.0 mm) to Ø29.5 in. (Ø750.0 mm).  Quick-connect poles to push target deep into the bore.

With a 20×20 mm PSD, it has a very large measuring range for large straightness errors typically seen in long cylinders. The wheeled measuring tips make it extremely easy to insert the target into the bore and push deep into the cylinder.

Use with Bore9 Software to collect the data and calculate the straightness.

Applications

  • Straightness and concentricity checks on large-caliber gun barrels.
  • Straightness and concentricity checks on long cylinders.
  • Straightness and concentricity checks on long extruder barrels.

Features

  • 20×20 mm PSD, (position sensing device) with .0001 in. (0.001 mm) resolution (with R-1307+R Readout) and < 0.5% linearity.
  • Self-centering, bore adapters that uses measuring legs with roller bearing tips for easy insertion into very deep bores.
  • Can perform straightness checks on gun barrels or cylinders up to 66 feet (20 meters) long.
  • For bores using the roller tips, the A-516-II can accommodate bores from Ø3.90 in. (Ø99.1 mm) to Ø29.5 in. (Ø750.0 mm). 
  • For bores using non-roller tips, the A-516-II can accommodate bores from Ø2.68 in. (Ø68.0 mm) to Ø29.5 in. (Ø750.0 mm). 
  • Quick-connect poles for easy insertion into the bore.
  • Supports our R-1307BC & R-1307-2.4XBE 2-Axis Readouts.
  • Use with Bore9 Software to record alignment data, calculate the straightness and plot the alignment data points.
