Engineer Tools: Calculate the Tolerances for Your Shaft & Housing Unit
Machine your shaft and housing unit within the recommended tolerances to achieve the right ball-bearing press fit for your application.
The Importance of Calculating Tolerances
Why is it important to perform tolerance calculations?
High-speed applications produce a high centrifugal force that causes the inner ring of a bearing to expand. This could cause a press-fit bearing to turn into a bearing slipping on the shaft. If this results, then drastic machine malfunctions could occur.
It’s important that the inner ring of the bearing stays pressed into the shaft during operation.
This calculator helps you find the right machined shaft and housing tolerance recommendations to ensure a press fit is achieved.
The RPM adjustment factor is based on GMN ball bearing standards and our many years of bearing experience.
Check out our Thermal Range Calculator to see how materials will grow and/or shrink when in operation.
