Maximum and minimum interference of 636 bearing
When calculating interference based on your application, consider the following:
a) Load and interference (△df)
When loaded, the bearing ring will deform to a certain extent. Over time, the interference fit of the inner ring of the bearing will loosen as the load increases, and the ring may begin to slip under the action of rotational load. Therefore, the interference must match a certain load. The greater the load, the greater the interference, especially when subjected to impact loads.
When the bearing bears radial load, the interference of the inner ring decreases. Generally, it can be obtained by using the following formula:
b) Temperature conditions and interference (△Ad)
During operation, the temperature of the bearing ring is usually higher than that of other components, which may cause the inner ring to loosen. The interference reduction due to temperature difference can be calculated by the following formula:
c) Fit to hollow shaft (AH)
If the bearing is to be installed on a hollow shaft with an interference fit, in order to achieve the same surface pressure between the inner ring and the shaft, the interference fit used is usually larger than that installed on a solid shaft. The following internal and external diameter ratios are important when deciding to use a fit.
When the inner and outer diameter ratio of the hollow shaft Ci > 0,5, it will have a slight impact on the fit. If the average outer diameter of the inner ring is not known, the inner-to-outer diameter ratio Ce can be accurately calculated using the following equation.
