GB 4932 QGB 49 Internal Clearance Gauge Features and Advantages

Structural Design: The gauge features a groove design, where two halves of the measuring ring jointly bear the appropriate pressure of the roller assembly, effectively preventing damage to the rollers or the measuring area.

High Precision: For sizes ≤ 38 (QGB 4920 to QGB 4938), the precision is less than 1 μm; for sizes ≥ 40 (QGB 4940 to QGB 4960), it is less than 2 μm.

Adjustment Function: Equipped with adjustment screws, the gauge body can be compressed to facilitate smooth insertion into the roller assembly, enhancing operational convenience.

Application: Primarily used for measuring the internal clearance of double-row cylindrical roller bearings, it finds extensive applications in mechanical manufacturing, medical devices, power equipment, automotive industry, and aerospace fields.

QIBR - GB 4932 QGB 49 Internal Clearance Gauge Optimization

Surface Treatment: The surface of the gauge can be treated according to customer requirements and working environments, with coatings such as titanium nitride and titanium aluminum nitride.

Heat Treatment: Appropriate heat treatments, such as quenching and tempering, are applied to enhance hardness and wear resistance.

More customization: QIBR can optimize and customize the gauge's accuracy and dimensions according to customer requirements.

QIBR - GB 4932 QGB 49 Internal Clearance Gauge Quality Control

Dimension measurement: Various specialized high-precision instruments are used to measure multiple dimensions of the QGB30 and QGB10 internal clearance gauges, achieving a maximum precision of 0.001 mm.

Hardness measurement: The surface hardness of the QGB30 and QGB10 internal clearance gauges is measured using a hardness tester, with a measurement precision of ±0.5 HRC.

Metallographic Analysis: Professional metallographic microscopes are used to analyze the internal metallographic structure of the metal.

Raw material control: Steel and components are sourced from ISO 14001 certified suppliers, ensuring product stability while promoting sustainable development.
