Roundness Measurement Systems
Starrett RT800
High speed roundness systems for bearings, automotive and precision industries
A range of roundness products robust enough for the shop floor but
accurate enough for any inspection room.
Working closely with manufacturers across a wide range
of industries including bearings, automotive and aerospace
engineering we have focused on the key attributes that are most
important for quality control in today’s precision industries.
The new Starrett RT800 offers a flexible solution for all your
roundness and form requirements with a variety of systems and
application specific accessories along with fixtures that can be
tailored to your specific need.
Speed (3 parts/minute including set-up)
The most important benefit these systems offer is speed. In precision
industries as manufacturing volumes increase all too often the bottleneck is
metrology. High measurement throughput systems ensure higher sampling
rates are achieved while also supporting increased manufacturing volumes.
Precision (±25 nm spindle accuracy)
Although many times faster than traditional benchtop roundness
systems there is no loss of precision or accuracy. Full ISO compliant
measurements can be taken with ±25 nm accuracy and 30 nm gauge
resolution.
Robustness (suitable for 24/7 operation)
All systems are designed for constant 24 hour, 7 days a week use in
demanding shop floor environments; manufactured using only the
most durable and hard wearing materials.
Ease of use (touchscreen software)
The X-sight touch screen software platform with intuitive navigation make the
RT800 roundness system as easy to use as a SatNav or SmartPhone with
everything you need at your fingertips.

X-sight touch screen software
• Increase output
• Reduce scrap
• Ensure part traceability
• Get it right the first time
What can it measure?
The Starrett RT500 and RT800 are ideal for measuring high
volume production parts across a wide variety of industries
including:
Bearings – Races, Balls, Needles and Rollers
Automotive – Valves, Con Rods, Pins and Brake Discs
Process Control
– Grinding, Turning, Milling and Honing
and many more...
Patented gage orientation
Using a patented gage orientation with its robust locking mechanism
changing orientation from roundness to flatness or internal to
external only takes a few seconds.
Accurate gaging
All systems incorporate an accurate and reliable Talymin gauge
technology, delivering 6 nm resolution.
Patented Rapid CenterTM
Rapid Center avoids valuable cycle time being lost on manual part
centering. On most parts precision results are achieved following a
very simple and fast loading procedure. Now roundness
measurements can be made in less than 30 seconds including part
loading, centering, measurement, analysis and results display!
Magnetic fixture with centering attachment
Accessories and standards
A full range of accessories and standards are available to support the
instrument. These include Magnetic chuck, Rapid Center fixture, Glass
hemisphere, Calibration set, Precision test cylinder, Cresting standard,
Stylus kit, Flick standard (20 µm or 300 µm) and replacement air filter
modules­.
