spherical roller bearings
Product Description
Outside rollaway nest is in shape of sphere, together with the function of self aligning, thus can compensate the error caused by non-concentricity and axes deflection, but relative lean of inside ring and outside ring should not excess 3 degree.
1. Outside rollaway nest is a part of sphere, bearing has the function of inside self aligning, so as to suit the relative defluxion between axes and bearing saddle bore.
2. Can suffer from radial heavy loading and impacting loading; meanwhile, can also suffer from certain bidirectional axial loading.
3. This kind of bearing can limited the axial displacement of axe or crust in the range of bearings axial windage.
4. The structure and features of such kind of bearings are just the same as self-aligning ball bearings, if the condition of loading capacity and limited speed allowed, they can replace each other.
