SKF bearing 1218 self-aligning ball bearing  

SKF bearing 1218 self-aligning ball bearing SKF High speed bearing sel-aligning ball bearing     Self-aligning ball bearing has two sorts of structure: cylindrical hollow and conical hollow, and the material of cage is steel plate, artificial resin, and many others.its characteristic is that the outer ring raceway is spherical and has computerized self-aligning, which could compensate the mistakes because of making self-aligning ball bearings with extremely good concentricity and shaft deflection.in particular go through radial load, and might bear small axial load.the axial displacement of the shaft (shell) is constrained within the clearance restrict, and it has the function of automatic self-changing, permitting the regular operation under the scenario of the pretty small inclination of the inner and outer components. it's far appropriate for the components where the coaxiality of the assisting seat hollow cannot be strictly guaranteed.
