he range of WZA spherical roller bearings EX comprises eight series. The smallest bore diameter is 20 mm, the largest outside diameter is 1 220 mm. Narrow bearings with a low cross- section, for example of series 230, allow high speeds and require little mounting space. For special operating conditions, we supply special designs of spherical roller bearings EX. For oscillating loads, special spherical roller bearings of series N223..-EX with restricted dimensional tolerances and increased radial internal clearance are used. In contrast, wide bearings with a high cross-section, for example of series 223, have a very high load carrying capacity. We supply spherical roller bearings EX both with a cylindrical and with a tapered bore. As a result, there are several options for locating the bearings on the shaft, see also the section Tapered bore.
