Spherical plain bearings are appropriate for bearing arrangements where alignment movements between the shaft and housing have to be accommodated, or where oscillating or recurrent tilting must be allowed at comparatively slow sliding speeds.
The inner and outer rings are made of steel and are manganese-phosphated. The sliding contact surfaces are treated with a running-in lubricant which reduces friction and wear during the running-in period.
These bearings have a permissible operating temperature range of -30 to +130°C. However, if temperatures reach above +120°C, their load carrying capacity will be reduced. Please note appropriate temperature grease will have to be used.
