OVAL BEARING UNITS UCFL203 ISB HT HIGH TEMPERATURES
ISB bearing units may be used not only in normal temperature
conditions, but also in high temperature applications.
ISB bearing units for High Temperature (HT) use suitable kind of
rubber seal and the grease for specifi c operating temperature as
shown in the table reported below.
For heat resistance application, it must be taken in consideration
the decrease of load rating of the bearings and a larger-thannormal radial internal clearance.
Standard radial internal clearances for High Temperature
applications are C5 for both cylindrical and tapered bore
When temperature gap between the inner and the outer ring of
the bearing is extremely large, suitable radial internal clearance
must be determined.
