Detailed Description
(Inner Ring) The inner diameter-based track concentricity measuring device is a comparative measurement jig that quickly and repeatedly verifies the alignment of the track center with the reference axis of the inner ring component, when the inner diameter is set as the reference axis.
The inner diameter is a key criterion for determining the fit with the shaft or mating component during assembly, and in many processes, the inner diameter serves as the de facto reference axis. If the track center is misaligned with the inner diameter reference axis, the track will rotate eccentrically during assembly, resulting in a biased contact point and increased local load, increased noise/vibration, uneven wear, and reduced durability. Therefore, controlling the inner diameter-based track concentricity is a key management item for stabilizing the quality of the inner ring's functional surface.
The measurement principle is to align the component with the inner diameter as the reference axis and read the eccentricity of the track section as rotational displacement. First, an approved sample is selected as a master sample to set the inner diameter reference conditions for the jig. When the inner ring is inserted and seated on the inner diameter reference support, the inner diameter is aligned with the reference axis. A dedicated contact (ball/probe) aligned with the track surface is brought into contact with the track measurement section under specified conditions. A dial gauge or digital indicator is then set to zero. The difference between the maximum and minimum gauge values is read while rotating the part to determine track eccentricity.
The dedicated support structure stably forms the inner diameter reference axis and standardizes track contact conditions. This makes it ideal for quickly identifying track concentricity deviations during the process and for early detection of eccentricity caused by changes in processing conditions.
This product applies the latest technology to provide high precision and reliability. It delivers stable performance even under demanding measurement conditions required in industrial environments, and features a user-friendly interface that anyone can easily use.
