Self-aligning ball bearing ETN9
Self-aligning ball bearing is two groove of the inner ring and outer ring for the ball rolling way between the form of a drum, assembly have the roller bearings. Outer ring groove of curvature of the center and bearing center, so consistent with automatic self-aligning ball bearing the same tone heart function. In the shaft, shell buckling, can appear be automatic adjustment, not increase bearing burden. Spherical roller bearing can bear radial load and two direction of the axial load. The radial direction load capacity, suitable for heavy load, impact load.
features of Self-aligning ball bearing: outer ring groove is spherical shape, have automatic adjustment of mind, so as to compensate concentricity and deflection made self-aligning ball bearing into the error of the inner, but it shall not exceed 3 degrees relative gradient.
The main use scope: self-aligning ball bearing is designed to withstand heavy load and impact load, precision instruments, low noise machine, automobile, motorcycle, metallurgy, rolling mill, mine, petroleum, papermaking, cement, the sugar industry, general machinery, etc.
