These types are designed for applications where normal to high temperatures are encountered and applications where one or more floating bearing units are required
The floating unit allows the bearing to move axially as the shaft expands from rising temperatures The fixed unit maintains shaft location
The bearings have a loose internal fit
The SAL unit is equipped with a self-aligning SM wide-inner-ring bearing and a self-locking collar
The external aligning ring is fitted to the spherical surface of the outer ring
These types are equipped with oil-tight seals theyre normally fitted for oil lubrication, but they can be equipped for grease lubrication when specified
Before installation, lubricate with high-grade automotive oil, turbine oil or ball-bearing grease
The units are assembled with a spacer ring (fixed type) By removing the spacer ring, the assembly becomes a floating unit
