Metric Smooth Plug Gauge Gage High Precision Φ50 Inner Diameter Plug Gage Inspecting Tool (Φ50 H7)

Key Features of Smooth Plug Gauge Gage
Crafted with excellence, our high - precision inner diameter plug gauge stands out for its exceptional material quality and performance, making it a top choice for rigorous industrial inspection:​
Premium Material Selection​
We take pride in using high - grade materials to ensure the gauge's durability and accuracy. The measuring surfaces are made from tungsten steel (carbide), renowned for its extreme hardness (up to HRC 90+) and wear resistance. This material can withstand frequent use in harsh industrial environments, far outperforming ordinary steel in longevity. For the gauge body, we utilize high - quality bearing steel (SUJ2), which offers excellent toughness and stability. It resists deformation even under prolonged stress, maintaining the gauge's structural integrity over time. The combination of these materials ensures the gauge remains reliable through countless inspections.​
Superior Measurement Precision​
Calibrated specifically for the Φ50 H7 tolerance, this plug gauge delivers pinpoint accuracy. The "go" and "no - go" ends are ground to strict dimensional standards, with a tolerance of just a few nanos. This level of precision allows it to detect even the smallest deviations in workpiece inner diameters, ensuring that only parts meeting the H7 specification pass inspection. Whether used in automotive part manufacturing or aerospace component testing, you can trust it to provide consistent, repeatable results.​
Long Service Life​
Thanks to the wear - resistant tungsten steel measuring surfaces and robust bearing steel body, the gauge boasts an impressively long lifespan. Unlike gauges made from 普通钢材 (ordinary steel) that wear down quickly, ours retains its precision even after thousands of insertions. This durability reduces the need for frequent replacements, saving you time and costs in the long run.​
Exceptional Wear Resistance​
The tungsten steel measuring tips are highly resistant to abrasion, corrosion, and impact. They can handle contact with various workpiece materials, including metals and alloys, without showing signs of wear. This resistance ensures that the gauge's critical dimensions remain unchanged over time, eliminating the risk of inaccurate measurements due to material degradation.​
Stable Performance in Varied Conditions​
Both tungsten steel and bearing steel have low thermal expansion coefficients. This means the gauge maintains its accuracy across a wide range of temperatures (from 10°C to 40°C), minimizing measurement errors caused by environmental temperature fluctuations. It performs reliably in factory floors, inspection labs, and other settings where temperature may vary.​
These features make our plug gauge not just a measuring tool, but a long - term investment in quality control. It’s designed to meet the demands of high - precision industries, ensuring your workpieces adhere to strict standards with every inspection.
