52222 Bearing Product Overview & Core Advantages
The 52222 is a metric thrust ball bearing engineered for demanding applications requiring high axial load capacity and precision performance. Designed specifically to accommodate thrust loads in a single direction, this bearing features a robust construction with hardened chrome steel components. Its key advantages include a high axial static load rating of 82,125 lbf and a high axial dynamic load rating of 28,125 lbf, making it suitable for heavy-duty machinery. The open design allows for high-speed operation up to 1,800 rpm and efficient heat dissipation, while the stainless steel cage ensures durability and reliable operation within a temperature range of -30°C to 110°C.
