HZK spherical roller bearing:
Spherical roller bearings offer an attractive combination of design features, which are making them irreplaceable in many demanding applications.Spherical roller bearings accommodate misalignment between the shaft and housing without increasing friction or reducing bearing service life.Optimized internal geometry within the available cross section provides maximum radial and axial load carrying capacity.CCJA consists of symmetrical rollers, two hardened window-type steel cages centred on the outer ring raceway via a floating guide ring between the two roller rows.The favourable design characteristics combined with simplified mounting procedures enable more efficient and compact machine designs.

Spherical roller bearings have two rows of rollers with a common sphere raceway in
the outer ring and two inner ring raceways inclined at an angle to the bearing axis.
This gives them an attractive combination of design features making them irreplaceable
in many demanding applications. They are self-aligning and consequently insensitive to
misalignment of the shaft relative to the housing and to shaft deflection or bending.
