BAB self-aligning roller bering is designed to adapt to the circumstance of heavy load.It have two rows of symmetric spherical rollers.The roller may freely adjust position in the outer spherical raceway.which may compensate the shaft deformation and non-alignment error of bearing seat.
The quantity .length and diameter of roller in BAB self-aligning roller bearing are the max.value that the structure allows.The close contact between the roller and raceway evsures the uniform stress distribution and enables the high bearing capacity of bearing.
In the touch working conditions.such as the circumstance of vibration,BAB may provide the self-aligning roller bearing with smaller dimensional tolerance and bigger radial play.
