To determine ways to reduce bearing vibration, noise, and friction torque, Sugawara develops Anderon meter (Innovative Tribomaterials Group at the National Institute for Materials Science)
The Innovative Tribomaterials Group pursues research on new tribomaterial coatings for ball bearings designed for use in extreme environments, including high temperatures and vacuums. Sugawara Anderon Meters and pusher torque sensors are designed to evaluate ball bearing performance and to determine how to reduce bearing vibration, noise, and friction torque using solid lubricant coatings in place of lubrication oil.
Anderon Meter for miniature-small size ball bearings
Anderon Meter ADA-100/ADM-101
High-precision measurements of ball bearing vibrations:
The Anderon Meter rotates the bearing inner ring at a speed of 1,800 r/min and incorporates a speed sensor to detect radial vibrations of the outer ring, displaying them as Anderon values.
Features:
- Capable of measuring small diameter high-performance bearings
- Uses a Sugawara compact speed sensor with flat frequency profile for vibration detection
- Can be used to measure bearings of different sizes simply by changing the arbor
- Can be combined with an automated unit to configure an automated system
- Compact, space-saving design

Anderon Analyzer ADA-100
For measurements adhering most closely to Anderon theory:
In addition to measuring Anderon values, the ADA-100 is also capable of instantly acquiring the spectrum corresponding to the Anderon values for faster and easier identification of defects and factors leading to complaints related to roller bearings. Also enables direct viewing of theoretical vibration components to provide effective support for vibration theories.
Features:
- Able to display the Anderon spectrum in real-time, a feature not previously available with general-purpose FFT analyzers.
- Applies the “band width mean processing” concept to provide spectral measurements and display more closely adhering to Anderon theory.
- Measurement units available include Anderon, µinch/rad, µinch/sec, µinch, µm/rad, µm/sec, µm, nm/rad, nm/sec, and nm.
- Also measures standard Anderon values as well as the spectrum. Can also be used as a user-friendly Anderon meter.
- High-speed digital processing has dramatically reduced spectral calculation times (to approx. 0.2 s).
- The (optional) built-in printer can be used to produce hard copies of the screen display.
ADA-100 typical screen displays:
Anderon spectrum display
Envelope mode display
Analog meter mode display
Anderon Meter Indication Unit ADA-15
ADA-15 is a low-cost model of Anderon readout.
Features:
- Displays L, M, and H band Anderon values at the spindle speed of 1,800 r/min
- Comparator function of U band and PEAK COUNT
- AC and DC voltage signal output of the data
- Can be combined with an automated unit to configure an automated system
