The dimensions for the shoulder diameters of radial bearings are rounded up or down to a level that is suitable for general machinery applications. Diameter dimensions of the inner ring are rounded down, whereas those of the outer ring are rounded up.
Load and speed ratings and fatigue load limits
The values of these parameters are rounded to a level that fits the accuracy of the calculations they are intended to be used in.
Masses are rounded to approximately ±5% of the actual value. They do not include the weight of any packaging.
Temperatures are typically rounded to 5 °C and are presented in both units (°C and °F). Because of the rounding, temperature values may not match when using unit conversion formulae.
