Spherical plain bearings

Spherical plain bearings are pre-finished machine parts (DIN ISO 12240) with spherical sliding surfaces which are constructed for tilting, swivelling or circular movements at slow sliding speeds. They are particularly suitable for bearing arrangements where movements between shaft and housing or alignment movements have to be accommodated.

Spherical plain bearings can be divided into three main groups. These are available as a type requiring maintenance or maintenance free:

Factors reducing the lifetime of spherical plain bearings are for example dirt, humidity and vibrations. For critical applications please contact WSW.

Especially suitable for applications in the Offshore industry are our Composite spherical plain bearings which are maintenance free and saltwaterresistant.
