1, cylindrical roller bearing ring relative to the situation relative to the direction of load load for the ring of rotating or oscillating, interference or transition fit should be selected. Fixed relative to the direction of load ring should select a clearance fit. When with the inseparable type SKF bearing when the mobile support is made, it should be fixed relative to the direction of load rings as swimming rings, select a clearance fit or transition fit.
2, the type and size of the load when subjected to shock loads or heavy load, generally lighter than normal, you should choose Load closer cooperation. Radial cylindrical roller bearings radial equivalent dynamic load for load size ratio of radial dynamic load rating CR and PR Division, greater the greater load combined with an interference fit. PR/CR light load load size equal to or less than 0.07 normal load is greater than the 0.07~0.15 heavy load greater than 0.15
3, size of cylindrical roller bearing with FAG bearing size increases, select interference interference larger larger the gap clearance.
4, clearance of cylindrical roller bearing with interference can result in NSK bearing clearance decrease, inspection clearance of the bearings after installation meets the requirements for correct selection of tie and bearing clearance.
5, other factors such as shaft and housing materials, strength and heat conductivity; external and cylindrical roller bearing ways and thermal conductivity of the heat produced in the heat, bearing installation and tuning performance, affect the selection of fit.
