The seals in the radial part are in ZRS execution or ZZ execution whereas the seals in the axial part are in Viton. This is made in order to guarantee the protective device to the bearing also during its working at high temperature.
The lateral thrust cover is made in case-
The central pivot is made in low carbon C20/C45 steel, which guarantees high resistance and is highly suitable for welding.
The cages inside radial and axial part are manufactured in bronze. Radial clearances may vary from CN to C3.
Combined bearings for high speed have the following technical characteristics:
Outer ring and little axial roll are manufactured in case-
Inner ring and pin are manufactured in core-
THE BEARINGS ARE IN ZRS EXECUTION
The bearings are supplied with lubrication hole.
Technical Characteristics
Combined bearings for high speed maintain the same technical characteristics as fixed combined bearings.
They are provided with bronze cages both in the radial and in the axial part, therefore they can rotate at a high number of revolutions.
They are provided also with Viton seals, so that they can bear heavy working conditions and high temperatures.
