Conical hole with sealed type

The tapered hole sealed self-aligning ball bearing is a practical upgraded version of the self-aligning ball bearing, which integrates three core designs: tapered hole expandable positioning, double row steel ball self centering, and integrated double-sided sealing. It retains the core advantage of compensating for coaxiality deviation of the self-aligning ball bearing, and achieves seamless locking of the shaft system through tapered holes. At the same time, the sealing structure achieves dust, water, and grease leakage prevention, and is suitable for general industrial conditions such as light and medium loads, large installation coaxiality deviation, humidity and dust, and precise positioning of the shaft system. It is a highly adaptable support choice for textile machinery, conveying equipment, fans, agricultural machinery, motor end caps, and other scenarios.
