| With instrument uncertainty to 2 millionths of an inch
(50 nanometers), the Labmaster Universal (LM U306270) is
suitable for virtually all Internal (ID) and external
(OD) measuring applications. This laser-based universal
length measuring system (ULM) has been developed by
Pratt & Whitney for gage calibration laboratories that
need to precisely measure length, outside diameter,
inside diameter, pitch diameter, lead, major/minor
diameter, taper, linear displacement, and thickness.
High accuracy is maintained by its laser
interferometer, zero Abbe offset design, and large
measuring table with center position, height, pitch, and
yaw controls. The computer-controlled precision air
bearing slide and gaging fingers remove
operator-influenced errors commonly observed with
traditional gaging methods by maintaining constant
force. It also greatly minimizes wear and tear to both
the measuring standards and the instrument.
The ULM is capable of measuring gage blocks, end
standards, plain rings, threaded rings & plugs, API
gages, pin & plug gages, tapered plugs, cylindrical
setting gauges, micrometers, indicators, LVDTs,
calipers, and snap gauges with instrument uncertainty to
2 millionths of an inch (0.05 micron). It is suitable
for virtually all ID and OD applications through its
wide 0.020-inch (0.5 mm) to 14-inches (356 mm) measuring
range. The ULM includes Pratt & Whitney’s GageCal
software that automatically enters tolerances for rings,
plugs, pins, balls, threads (calculates pitch/major
diameter) and flags out of tolerance conditions.
The Labmaster Universal (U306270) is also a popular measuring
instrument in the bearing industry. The five basic types
of anti-friction bearings can easily be measured on the ULM. They include: tapered bearings, needle bearings,
ball bearings, spherical bearings, and cylindrical
bearings. Measuring characteristics include: internal
diameter, external diameter, outer raceway diameter,
inner raceway diameter, radial internal play (radial
internal clearance) and axial internal play (axial
internal clearance). Please visit our Pratt & Whitney
Bearing Measuring Instrument.
Other specialty measuring applications include:
gears, shafts, optics, film thickness, automotive parts,
aerospace parts including aircraft engine parts, and
your precision components can all be measured on the ULM.
