Bearing Vibration Testers
Anderon Meters and Calibrators

Anderon Meters
ADM-104 Drive Unit
For high-precision measurementsof ball bearing vibrations
Rotating the inner ring of a ball bearing at 1,800 rpm,
the Anderon meter measures the radial vibrations of
the outer ring with a velocity sensor. The measurement
result is divided into seven frequency bands including
Low (50–300 Hz), Medium (300–1,800 Hz), and Highband (1,800–10,000 Hz), and indicated for each bandin a unit called Anderon.
The Anderon value can be used to not only grade
bearings but also to identify defective components.

Features
Achieves accurate and highly reproducible measurements
owing to equipment background noise of only 0.1 Anderon(≈ 0.77 μm/s) or less, enabling efficient acquisition of highly
reliable data

Supports measurement of bearings ranging
from ultra-small to medium-sized
Selecting from either of two Pusher models enables measurementof bearings ranging from ultra-small with an inner diameter of 1
mm to medium-sized with an outer diameter of 100 mm.

By changing the Pusher, a single Anderon meter can measure
bearings ranging from ultra-small with an Inner Diameter (ID)of 1 mm to medium-sized with an Outer Diameter (OD) of 100mm.
The compact design allows for a table-top set-up.

Vibration detection

An Arbor, whose tip is made to match the ID of the bearing, is fitted
to the spindle, which is rotated at 1,800 r/min. The bearing innerring is slipped into the Arbor tip, and is rotated at 1,800 r/min.
A Pusher Head, made to match the OD of the bearing, is fitted tothe Pusher. The outer ring is held from rotating, being pushed inthe axial direction by the Pusher.
In this way, the inner ring rotates while the outer ring does not. By
setting the Velocity Sensor Contact on the top of the non-rotatingouter ring, the vibration in the radial direction of the outer ring isdetected.

Contact velocity sensor with flat
frequency characteristics
ADS-101 is a Sugawara-developed velocity sensor at the heart ofAnderon measurement.
Most of conventional velocity sensors have had multiple inherent
vibrations above 5 kHz making high-band measurements difficult.
The Sugawara ADS-101 improves upon this, achieving
measurements with flat characteristics up to 10 kHz.

ADA-105 Analyzer
Real-time spectrum and waveform
display of vibrations
The Anderon Analyzer ADA-105 is an equipment foranalyzing detected bearing vibrations.
Its spectrum display as well as Anderon value display ofeach band simplify and speed up analysis of bearing
defects.
In addition, bearing vibration quality can be standardizedon the basis of raw waveforms using a vibration-soundrecording and playback function.
Measured vibration can be analyzed in terms of innerring, outer ring, balls, and other components by inputting
bearing specifications (ball P.C.D, ball diameter, numberof balls, and contact angle).

Features

Real-time display of Anderon spectrum, a feature not provided
by general-purpose FFT analyzers.
Displays frequency and measurement values at any point in aspectrum by cursor pointing.
Measurement units: Anderon, μinch/rad, μinch/sec, μinch,μm/rad, μm/sec, μm, nm/rad, nm/sec, nm, cm/s^2, mG
30-second recording and playback of bearing vibration soundSound data, measurement data, measurement conditions,and screen shots can be saved to a USB memory.
Threshold values can be set for 7 bands and for "crest factor& frequency", enabling pass/fail judgements.
Up to 1,000 sets of measurement conditions can be saved
and searched from a list.

Anderon Calibrator ADC-101
This single unit can be used to calibrate all the analyzers
of Anderon meters and Waviness meters.
Periodic calibration is needed to obtain accurate values.
The Anderon Calibrator ADC-101 is an instrument forcalibrating bearing vibration testers. It can calibrate theanalyzers of all of Sugawara's bearing vibration testers.
It outputs electrical signals corresponding to themeasured value to the analyzers of Anderon meters
and Waviness/Roundness meters to calibrate them.

Features

Calibrates all of Sugawara's bearing vibration testers
in two modes

How to calibrate

Basic set of Anderon meters and Waviness/Roundness
meters, and their measurement principle is as follows.

Drive Units: ADM/LWM/BWM-*
Sensors:
ADS/LWS/BWS-*
Analyzers: ADA/SWA/LWA/BWA-*The Drive Unit rotates the bearing, the inner/outer ring, and thesteel ball under test, and outputs rotation pulse signals to theAnalyzer. The Sensor detects their vibrations and outputs voltage
signals to the Analyzer.
The Analyzer processes the rotation pulse signals and thevibration voltage signals, and displays the measurement result.
For calibration, the Anderon Calibrator ADC-101 outputs rotation
pulse signals and sine-wave signals corresponding to the set
vibration value to the Analyzer, to check if it correctly displays theresult.
