The protrusion amount of the angular contact ball is also called the grinding amount. It is calculated in a scientific way. When back-to-back, face-to-face or combined, through installation and extrusion, the calculated optimal preload amount and free play are calculated. Clearance value, so the bearing can maximize the design upper limit, which is convenient for users.
Measuring the protrusion of angular contact ball bearings is crucial for ensuring proper functioning and alignment in various applications, such as machinery and automotive systems. The protrusion measurement is typically done to ensure that the bearings are correctly seated and that there is proper contact between the bearing and its mating components. Here’s a general method and principle for measuring the protrusion of angular contact ball bearings:
Angular contact ball bearing protrusion measurement method:
Equipment Setup
- Use a measuring instrument such as a caliper or a micrometer.
- Ensure the measuring instrument is calibrated and in good condition.
- Prepare a flat and clean surface for the bearing and mating components.
Positioning the Bearing
- Mount the angular contact ball bearing in its intended location within the machinery or assembly.
- Ensure that the bearing is properly seated and aligned according to the design specifications.
Selection of Measurement Points
- Identify the specific points on the bearing or its housing where protrusion measurements are required.
- These points are typically defined in the engineering or assembly specifications.
Taking Measurements
- Place the measuring instrument perpendicular to the surface of interest.
- Gently touch the measuring instrument to the designated points on the bearing or its mating component.
- Record the measurements carefully.
Repeat Measurements
- Take multiple measurements at different points to ensure accuracy and consistency.
- Calculate the average protrusion value if multiple measurements are taken.
- Comparison with Specifications:
- Compare the measured protrusion values with the design or assembly specifications.
- Ensure that the measurements fall within the specified tolerances.
