self-aligning roller bearings : , where two of the inner ring raceway and the outer ring of spherical roller between the drum is equipped with roller bearings. outer ring raceway surface curvature center and bearing center line, and therefore have a self-aligning ball bearings with the same self-aligning feature. In the shaft, deflection occurs when the shell can be adjusted without increasing the burden bearing. Spherical roller bearings can bear radial load and axial load two directions. Radial load capacity, suitable for a heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. or use the adapter kit installed in the cylindrical shaft tube removal. Cage cage use steel stamping, forming polyamide and copper alloy cage cage car system
