(Note: The indicator's accuracy should match or be lower than the instrument's accuracy; otherwise, a high-accuracy indicator won't provide practical benefits, and a low-accuracy indicator won't fully utilize the instrument's potential.)

Q1: What is a concentricity tester?
A1: A concentricity tester is a precision measurement tool used to assess the alignment of the centers of two or more parts, ensuring they are concentric (i.e., share the same center axis). This tool is commonly used in machining and manufacturing to check the concentricity of components like shafts, bearings, and other cylindrical parts. By rotating the component and measuring any deviation from the desired axis, the tester provides insight into the part's precision and how well it will function in an assembly. Concentricity gauges are crucial in quality control to minimize mechanical errors, reduce wear and tear, and improve the overall performance of the finished product.

Q2: How does a concentricity tester work?
A2: A concentricity tester works by measuring the alignment between the center axes of a part and its rotating reference. The part being tested, typically a cylindrical component like a shaft, is mounted securely on a spindle or fixture. As the part rotates, one or more dial indicators or measuring probes are placed at key points along the part's surface, often at both ends. These indicators measure any deviation from the ideal concentric position, detecting even small variations in the part's roundness or alignment. The concentricity measuring equipment records the amount of offset or eccentricity, providing a precise measurement of how much the part deviates from being perfectly concentric. This helps ensure high precision in manufacturing, reducing mechanical errors and improving the performance and longevity of the final product.

Q3: How to ensure proper maintenance and care for the concentricity testers?
A3: To ensure the proper functioning and longevity of the concentricity testers, it is important to keep all components clean. If there is fine dust, use a blower balloon to gently remove it, and if there are oil stains or fingerprints, wipe them off with a soft cotton cloth. Do not attempt to disassemble the instrument, as this could compromise its measurement accuracy or cause damage. When not in use, always cover the tester with a dust cover to prevent dust accumulation. Additionally, apply anti-rust oil and store the tester in a dry environment to avoid rusting. To maintain its performance, regular inspections are recommended. If you have any questions during use, please contact customer service for assistance.

Tips: How to choose a proper dial indicator for your concentricity tester？

When selecting a dial indicator for a concentricity measuring equipment, the first factor to consider is accuracy. The dial indicator should have a high resolution to detect even the smallest deviations in concentricity. For precision work, an indicator with a resolution of 0.001 mm or 0.0001 inch is ideal, as it allows for fine adjustments and detailed measurements. The total range or travel of the dial indicator should also be appropriate for the expected variations in the workpiece, ensuring that the indicator can accurately capture the maximum deviation without bottoming out or overextending.

Another important consideration is the type of indicator and its compatibility with the concentricity tester. The most common types are mechanical dial indicators and digital indicators. Mechanical indicators are simpler, cost-effective, and sufficient for many applications, while digital indicators provide higher precision and easy-to-read results. When selecting an indicator, ensure that it fits the mounting setup of the concentricity tester and that the measuring probe is suitable for the workpiece material and surface. Proper indicator selection enhances measurement accuracy, ensuring reliable results for various applications.

In addition to the dial indicators available on this page, there are other dial indicators provided on our SISCO website you can choose from.
