1) Spherical roller bearing rings relative to the direction of the load relative to the load status of rotating or oscillating rings, should choose an interference fit or transition fit. Phase the fixed ferrule for the direction of the load should be selected clearance fit. For swimming in supporting non-separable type bearings should be relative to the load direction the fixed ferrule as swimming rings, select a clearance fit transition fit.
2) the type and size of the load when subject to shock loads or heavy loads, the general should be chosen than normal light load more closely match. For radial bearings, load size equivalent dynamic radial load Pr with radial rated dynamic load ratio of Cr to divide. The greater the load, with the greater the interference.
3) Spherical roller bearings size the greater the interference with the bearing size increases, the selected interference fit; gap with the greater the gap.
4) interference fit INA bearing clearance will result in reducing the bearing clearance should be tested after installation meets the requirements for the correct selection of the fit and bearing clearance bearing clearance.
5) with the selection of the other factors of the material of the shaft and the bearing seat, the strength and thermal conductivity properties, the external and the heat generated in the bearing, and its thermal conductivity pathway, the bearing mount and the adjustment performance and so affect.
