SKF polymer ball bearings are typically used in applications where resistance to moisture or chemicals is essential and steel bearings cannot be used or only with certain restrictions. In those applications, polymer ball bearings are an excellent solution from both a technical and economic perspective as they are characterized by the following properties:
- corrosion and chemical resistant
- high wear- and fatigue-resistant polymer
- self lubricating (no lubricant required)
- low coefficient of friction
- quiet running
- lightweight
- high specific strength (strength to weight ratio)
- high dimensional stability due to the low tendency to creep
- low lifecycle costs
- electrical insulator

Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si3N4). Because the silicon nitride ceramic material is such an excellent electrical insulator, hybrid bearings can be used to effectively insulate the housing from the shaft in both AC and DC motors as well as in generators.

SKF sensor bearing units are used to accurately monitor the status of rotating or linear components. These units are:
- compact
- robust and reliable
- simple and ready to mount

SKF needle roller thrust bearings are fitted with a form-stable cage to reliably retain and guide a large number of needle rollers. The very small diameter deviation of the rollers within one assembly enables these bearings to accommodate heavy axial loads and shock loads.

SKF cylindrical roller thrust bearings are designed to accommodate heavy axial loads and shock loads. They must not be subjected to any radial load.
The ends of the rollers are relieved slightly to modify the line contact between the raceways and rollers. This prevents stress peaks at the roller ends to extend bearing service life.
