Detailed description
23156CA/W33 Spherical Roller Bearing (Large Size),Petroleum Industry Bearings Special and standard bearings.
Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis.
Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions.
DXSZ Spherical roller bearing performance include, but are not limited to:
Symmetrical rollers self-adjust, providing optimal load distribution along the roller length. This keeps stresses low under all load
conditions and extendsbearing service life.
The rollers are manufactured to extremely tight tolerances for dimension and form. Each roller is virtually identical in size and shape to the
other rollers in the set. This optimizes load distribution over the rollers to maximize bearing service life.
The roller profile determines the stress distribution in the roller/raceway contact area. The special profile distributes loads more evenly along the rollers and prevents stress peaks at the roller ends to extend bearing service life.
Self-guiding rollers reduce friction and frictionalheat. A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
All spherical roller bearings contain strong metal cages. This enables them to tolerate high temperatures and all lubricants.
Basic design bearings
Depending on their series and size, standard spherical roller bearings are manufactured to one of following basic designs:
CA: Integral brass cage, double row symmetrical roller, inner ring ride
CC: Two window-type steel cages, double row symmetrical roller, inner ring ride
MA: Machined brass cage, outer ring ride
MB: Machined brass cage, inner ring ride
