Radial insert ball bearings, spherical (S - type bearings ) S-type bearings units are preferably used for applications calling for simplicity of design and assembly. They are used, for instance, in agricultural machinery, conveyor systems and construction machinery. A S-type bearing unit comprises, a deep groove ball bearing sealed at both ends, with a spherical outside diameter and a grey-cast iron or pressed steel housing. We offer S-type bearings for shafts in inch and metric dimensions and the suitable plummer block housings and flanged housings (some housing dimensions deviating from former housing dimensions). S-type bearings are used almost exclusively as locating bearings. Therefore, they are particularly suitable for supporting short shafts and for applications where only minor thermal expansions are likely to occur. Minor expansions of the shaft are compensated for by the axial clearance of the bearings.
