When materials other than steel are used for shafts and housings, the fits between the inner ring and the shaft and the outer ring and the housing change because of difference in the expansion coefficient of each material as the temperature rises during the rotation of the bearing. Therefore, it is necessary to set the resultant fit with expansion coefficients in consideration. The calculation formula of the change in interference is shown below.Δ dTE = (α1‒α2 )× d × Δ TΔ dTE : Change in interference caused by difference in the expansion coefficients mmα1 : Bearing expansion coefficient 1/°Cα2 : Shaft and housing expansion coefficient 1/°Cd : Reference dimension of resultant fit mmΔ T : Temperature increase by bearing rotation °C(Expansion coefficient: See Table 13.19 in “13. Bearing Materials.”)

When bearing rings are installed with an interference fit, tensile or compressive stress may occur along their raceways. If interference is too great, this may cause damage to the rings and reduce bearing life. The maximum stress due to the resultant fit must not exceed approximately 127 MPa for safety. If the value is to be exceeded, consult NTN Engineering.See section “17.4 Resultant fit surface pressure” for the calculation method of maximum stress due to the resultant fit.

For rolling bearings, it is necessary to fix inner and outer rings on the shaft or in the housing so that relative movement does not occur between fitting surfaces during operation or under load. This relative movement between the mating surfaces of the bearing and the shaft or housing can occur in a radial direction, an axial direction, or in the direction of rotation. Types of resultant fit include tight, transition and loose fits, which describe whether or not there is interference between the bearing and the shaft or housing.The most effective way to fix the mating surfaces between a bearing and shaft or housing is to apply a “tight fit.” The advantage of a tight fit for thin walled bearings is that it provides uniform load support over the entire ring circumference without any loss of load carrying capacity. However, with a tight fit, ease of installation and disassembly is lost; and when using a non-separable bearing as the floating-side bearing, axial displacement is not possible. For this reason, a tight fit cannot be recommended in all cases.

Interference decreases because the mating surface is smoothed by the resultant fit (surface roughness is reduced). The amount the interference decreases depends on the roughness of the mating surfaces. It is generally necessary to anticipate the following decrease in interference.For ground shafts: 1.0 to 2.5 μmFor machined shafts: 5.0 to 7.0 μmThe interference including this decrease amount is called effective interference.

Bearing fit is governed by the tolerances selected for bearing shaft diameters and housing bore diameters.Widely used fits for Class 0 tolerance bearings and various shaft and housing bore diameter tolerances are shown in Fig. 7.1.Generally-used, standard fits for most types of bearings and operating conditions are shown in Tables 7.2 to 7.7.

(1) For bearing rings under rotating loads, a tight fit is necessary. (Refer to Table 7.1) “Raceways under rotating loads” refers to raceways receiving loads rotating relative to their radial direction. For bearing rings under static loads, on the other hand, a loose fit is sufficient.
