To measure a male spherical rod end, follow these steps: 1. **Thread Size**: Use a caliper or thread gauge to measure the diameter of the threaded shank. This will give you the nominal thread size. Check the thread pitch using a thread pitch gauge to determine the number of threads per inch (TPI) or the distance between threads in millimeters for metric sizes. 2. **Ball Bore Diameter**: Measure the inner diameter of the spherical ball where the mating component will be inserted. This is crucial for ensuring compatibility with the shaft or bolt. 3. **Ball Width**: Measure the width of the spherical ball. This is the distance across the ball at its widest point. 4. **Housing Width**: Measure the width of the rod end housing, which is the distance across the housing that encases the spherical ball. 5. **Overall Length**: Measure the total length of the rod end from the tip of the threaded shank to the opposite end of the housing. 6. **Shank Length**: Measure the length of the threaded shank from the base of the housing to the end of the threads. 7. **Head Diameter**: Measure the diameter of the rod end head, which is the outermost part of the housing. 8. **Misalignment Angle**: Determine the maximum angle at which the rod end can pivot relative to the shank. This is often specified by the manufacturer. 9. **Material and Finish**: Note the material (e.g., steel, stainless steel) and any surface finish or coating, as these affect performance and suitability for specific environments. These measurements ensure proper fit and function in mechanical assemblies. Always refer to manufacturer specifications for precise details.
