Bearing length
The size identification is separated from the rest of the bearing designation by an oblique stroke, e.g. 618/8 (d = 8 mm) or 511/530 (d = 530 mm). This is also true for standard bearings in accordance with ISO 15 that have a bore diameter of 22, 28 or 32 mm, e.g. 62/22 (d = 22 mm). Webthe bearing loads acting on the bearing via the wheelset journal and the axlebox housing . For railway applications, it is preferable to calculate the life expressed in operating mileage, in million km where L10s = basic rating life (at 90% reliability), million km Dw = mean wheel diameter, m When determining bearing size and life, it is

WebFor a bearing length of 14.85mm, the load (W) is 72.534kgf, which is sufficiently close to F₁ (72.55kgf). If you wish to provide oil-way grooves in this bearing totalling, say, 3mm width, your actual bearing will need to be 17.85mm wide. However, if this is considered to be too small to provide sufficient location/guidance for the shaft, you ... WebBEARING LENGTH. Maximum length is determined by using a ratio of length to bore, not to exceed 4:1. For diameters less than 1/4 inch, use a smaller ratio. To determine proper bearing length, refer to the PV chart (page 42). It will give the unit load per square for a specific speed and shaft size. By dividing the unit load per square inch into ...
