45 , gives an overview of the pos-sible seals, their design characteristics and suitability to meet different demands. Note Further information about radial shaft seals, referred to in the table, can be found in the SKF catalogue 4006 “CR seals” or the “SKF Inter- active Engineering Catalogue” on CD-ROM or online at www.skf.com. Most bearing arrangements must besealed to prevent external contamina- tion and damp from entering the bear- ing. The efficiency of the sealing has a decisive influence of the service life of the bearing. In contrast to most other bearing types, which only move in one plane, the alignment capabilities of the spherical plain bearings manufacturer place extra demands on the sealing.When selecting appropriate seals,many factors have to be considered including• the permissible angle of tilt,• the available space, • the environmental conditions, • the efficiency of the industrial seal, • the type of lubrication and thefrequency of relubrication, and • the justifiable cost.Depending on the application, oneor other of the above factors will out- weigh the others. It is therefore not possible to establish general rules for sealing design.

Sealing strips can also be sup-plied by SKF in felt (FS strips) or, for high temperatures, in alumin- ium-boron silicate material (FSB strips).
