The Signalysis Bearing Test System reduces warranty claims and customer complaints by identifying defects in roller element bearings before they leave your facility. Pass/Fail analysis once left to subjective judgement and antiquated machinery is now obtained through advanced algorithms and a precise, quantitative process.

HOW BEARING TESTING WORKS

• Vibration data on the bearing is acquired
• Standard measurements (Anderon levels, FTF, BPFO, & BDF)are calculated
• Results are submitted to SigQC for evaluation
• Measurements are compared against customized tolerance limits identifying acceptable bearings
• A Pass/Fail or Go/No Go signal is dispatched to your production line

BEARING TEST SYSTEM COMPONENTS | SigQC:

• Application software at the heart of IQC
• Identifies product quality based on data source, acceptance tests, test cases and rejection limits
• Supports in-depth statistical analysis features to indicate Pass/Fail status and generate production reports
• Interface to test stand devices to control motors, relays, PLCs and indicator lights
• Bearing dimensional data is used to calculate defect frequencies that can be used to create acceptance tests and reject criteria.
