BEARINGS PRODUCTION RANGE

In case of more rows, the rollers have various lengths and are alternatively mounted.
To avoid side friction, one of the side of the roller can be crown profiled.
The boundary dimensions of RKB cylindrical roller thrust bearings conform to ISO 104:1979.
Angular misalignment between shaft and housing is not permitted.
In order to guarantee a proper arrangement of the rolling parts for the satisfactory operation, the cylindrical
roller thrust bearings have always to be submitted to a given minimum load, specially when high speeds,
high accelerations or rapid changes of load directions are involved.
Both machined brass and steel cages are available as standard.
RKB production range also includes inch size cylindrical roller thrust bearings, engineered up to 50 inches
outside diameter in conformance with RBEC accuracy specifications.
Executions requiring antirotation devices on the plates, lifting holes and integral radial roller bearings are
also available.
There are standard design variations of RKB inch series thrust bearings. Each design is based on a standard
single acting with addition of special components to modify its function: the AT aligning type with sphered
housing plate for a possible initial static misalignment up to 3°; the crane hook thrust type with the weather
shed pressed on the rotating plate; the DT double acting thrust bearing and the DAT aligning style
combination of DT and AT types; the SDT simplified double acting thrust with only one roller assembly and
two thrust plates.
