Wall Thickness Variation Measuring Instrument

During the machining of bearing rings (inner/outer rings), wall thickness uniformity (Wall thickness variation) directly affects rotational stability, load distribution, and service life. Uneven wall thickness can lead to eccentricity, vibration, and abnormal noise during operation.

Traditional inspection methods show clear limitations in controlling wall thickness variation:

Indirect measurement methods with limited accuracy

Wall thickness is conventionally calculated indirectly via separate measurements of outer and inner diameters, causing error accumulation and failing to reflect true thickness distribution

Unable to quickly identify maximum thickness variation positions

Difficult to locate the thinnest and thickest points, limiting effective machining correction

Low efficiency for large-size components

For medium-to-large rings (D ≥ 150 mm), traditional methods are inefficient and lack consistency

This instrument uses a dedicated measurement structure and high-precision sensing system to directly measure wall thickness variation and distribution, enabling fast and accurate identification of eccentricity and controlling quality issues at the source.

• Direct measurement of wall thickness variation
• No indirect calculation required; quickly obtains max and min wall thickness difference
• Accurate identification of eccentric positions
• Clearly identifies thickest and thinnest points to provide a basis for grinding and compensation.
• Improves rotational accuracy and stability
• Reduces vibration and noise caused by uneven wall thickness
• Optimizes machining process control
• Provides guidance for eccentricity correction during turning and grinding processes
• Improves inspection efficiency and consistency
• Reduces manual intervention and improves the stability and reliability of batch inspection.

This equipment is suitable for wall thickness variation measurement of medium-to-large bearing rings:

• Applicable inner diameter range: d150–330 mm
