If INA axial spherical plain bearings are combined with radial spherical plain bearings of dimension series E to DIN ISO 12240-1 in order to support radial forces, the axial and radial load must be distributed over both bearings. The pin in the shaft locating washer must have a radial release of approx. 1 mm or the pin must only be in contact with the large end face of the shaft locating washer.
Combination of INA axial and radial spherical plain bearings
Fr = radial load
dK = sphere diameter
1 mm = pin with radial release
For a bore diameter of d >= 160 mm or larger in the case of maintenance-free radial spherical plain bearings, the INA bearing must be fitted in a closed housing. The diameter D of the axial bearing corresponds to the inside diameter of the housing.
