Bearings Quality Inspection with Resonance Testing

NDT-RAM for Continuous, Objective Quality Monitoring

Are you a bearing manufacturer who needs to ensure 100% of parts sent to customers are defect-free? Would a fast, clean, easy, and objective method of evaluating the quality of every single part be beneficial to you?

Non-Destructive Inspection for End Product Evaluation or Process Monitoring

NDT-Bearings-application

Non-Destructive Testing Resonant Acoustic Method (NDT-RAM) evaluates bearing inner and outer races before assembly, testing with 100% inspection and simple pass / fail results. The system, sometimes called ping testing, is reliable and easy to use and can sort as fast as 3 seconds per part. In addition to testing end products, NDT-RAM can be used in various phases of production to monitor your manufacturing processes. Collect data to help predict machine and tool wear and alert you to needed changes.

The various NDT-RAM systems available from The Modal Shop can each handle a wide variety of part sizes and shapes – one system can fit all of your needs for bearing quality inspection.

Detect Defects: Cracks, Missed Operations, and More

Cracks / laps
Missed operations
- Missing chamfers
- Excessive outside dimensions
- Unground surfaces
Heat treat
- Through hardened vs Case hardened

Mixed product
Soft product
Gross defects
Short feedouts

NDT-RAM as an Alternative to Visual Inspection and Other Methods

Visual inspection: NDT-RAM is faster, objective, and more reliable
Magnetic particle inspection: NDT-RAM is clean, objective, and faster
Dye penetrant or liquid penetrant testing: NDT-RAM is clean, objective, and faster
Eddy current testing: NDT-RAM is faster
