iwis Wear Gauge Sets

Precise measurement of chain elongation – simple, fast and reliable

iwis wear gauge sets are the optimal solution for measuring wear-related chain elongation in roller chains and leaf chains. The patented precision gauges, made of high-quality stainless steel that is resistant to rust and corrosion, enable fast condition assessment directly on the installed chain – without disassembly and without the need for calipers.

They support predictive maintenance and help reduce unplanned downtime.

Technical Highlight

Precision where conventional measuring tools reach their limits

iwis wear gauges are specifically designed to reliably measure chain elongation even in hard-to-access installation environments. Thanks to their defined measuring contours, the gauge immediately indicates:

whether chain replacement is required
the percentage of elongation already reached

This provides a clear basis for maintenance and spare parts management decisions – reproducible, standards-oriented and user-friendly.

Your Key Advantages:

Direct measurement on the installed chain
Suitable for BS and ANSI roller chains
Clear indication of percentage chain elongation
Supports condition-based maintenance strategies

Versions & Dimensions

Suitable for nearly all standard applications

iwis wear gauge sets are available in two standard versions:

Set No. 1:
For BS and ANSI roller chains with pitches of
3/8", 1/2", 5/8", 3/4", 1"

Set No. 2:
For BS and ANSI roller chains with pitches of
1 1/4", 1 1/2", 1 3/4", 2"

Wear gauge sets for leaf chains are available upon request.

Robust design for continuous industrial use

The iwis precision wear gauge sets are made of durable stainless steel and are designed for daily use in industrial environments. Both the gauge and the case impress with high mechanical strength, long service life and easy handling.

Thanks to their rust- and corrosion-resistant design, the wear gauges are also suitable for sensitive application areas, such as food production or humid environments.

The result: reliable measurement results throughout the entire service life.
