Exhaustive range The SKF range starts with bearings having a 4 mm bore and the rod end range covers almost all normal require- ments. More information will be found in the following section. Wide operating temperature range Minimal maintenance Temperature is not a problem. There is a choie of SKFspherical palin bear- ings and rod ends for temperatures ranging from –50 to +300 °C. Fit and forget applies to most SKF spherical plain bearings and rod ends. They are maintenance-free. In some applications, where heavy loads and difficult environments prevail, there might be a need for some mainten- ance. However, this need is minmal for SKF plainbearings, as there is an opti- mal choice of five different sliding con- tact surface combinations and also seals executions are available. âž” page 44 ). The operationalreliability of the bearing arrangement will be much enhanced – a benefit for original equipment manufacturers as well as their customers. With or without seals SKF also provides a choice of seals. The most popular sizes of standard bearings are available withand withoutseals. Sealed bearings provide oppor- tunities to solve many sealing prob- lems simply by using standard bear- ings, saving space and above all ex- pense. The double lip industrial seal integral with the face of the outer ring efficient- ly protects the sliding contact surfaces from contaminants in normal environ- ments. If environmental conditions are difficult, the SKF high-performance seals of the LS design should be con- sidered (

In most applications, SKF spherical plain bearings of through hardened steel are the best choice; but in difficult environ- mental conditions, SKFmaintenance- free stainless steel spherical plain bear- ings may be preferred.Please contact the SKF application engineering ser- vice for other options.
