Spherical roller bearings Technical Information Date 2004-03-01 Publ. No. TI 0401 ® SKF spherical roller bearings for vibrating applications For machines with inherent eccentric motion such as vibrating screens and compactors, SKF developed the range of strong and robust spher- ical roller bearings for vibrating applications. The bearings are available in the 223 series with cylindrical or tapered bore from 40 to 240 mm. All spherical roller bearings for vibrating applications are uprated to the SKF Explorer specifications. Bearings with the current basic design have been in service since the early 1990ʼs and have proven to reduce the operating temperatures and extend the service life of the machinery. Operating temperatures have been observed to be 5 to 10 °C cooler than the bearings having the previ- ous design with one or two piece brass cages. Bearing service lives have been observed to increase by a factor of two. The choice of spherical roller bearing design depends on the vibration level (g force) developed by the vibrating screen, feeder, or compactor. • The SKF standard E design spherical roller
