CA-type self-aligning roller bearings feature a double-row, barrel-shaped roller design and utilise a solid brass cage. They operate smoothly, offer excellent heat dissipation, possess outstanding self-aligning capabilities and a high load-carrying capacity. They are primarily designed to withstand substantial radial loads whilst also being capable of withstanding axial loads in both directions; they are impact- and vibration-resistant, making them suitable for heavy-duty applications. The bearings are not self-sealing and have an open design; external sealing devices may be fitted according to operating conditions. They are widely used in heavy-duty industrial equipment such as metallurgical rolling mills, mining equipment, cement machinery, large fans, paper-making equipment and conveyors.
