Aligning ball bearings are two raceways in the inner and outer ring road rollers for between spherical, equipped with a spherical ball bearings. Outer ring raceway curvature center and bearing center line, and therefore have a self-aligning ball bearing with the same self-aligning feature. When shaft deflection occurs when the shell can be automatically adjusted without increasing the burden bearing. Spherical roller bearings can bear radial load and axial load in two directions. Radial load capacity for a heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or using an adapter sleeve, remove tube installed in the cylinder axis. Cage with steel stamping cage, forming polyamide cage and copper alloy machined cage. Aligning ball bearings cylindrical and tapered bore two structures, cage made of steel sheet, synthetic resin. It features an outer ring raceway spherical shape, with auto-Mind, can compensate for misalignment and shaft deflection made aligning ball bearings into the error, but the inner and outer rings relative inclination of not more than 3 degrees.
