The 4206 Double Row Angular Contact Ball Bearing is engineered for applications demanding superior rigidity, high load stability, and precise running characteristics. Featuring two rows of balls arranged back-to-back, this configuration provides a wide effective bearing spread, significantly enhancing moment load capability and axial rigidity compared to conventional single-row designs. With standard dimensions of 30mm bore, 62mm outer diameter, and 20mm width, the 4206 handles complex combined loads—both radial and bidirectional axial—making it the ideal choice for critical equipment such as pump systems, precision gearboxes, and medium-speed machine tool spindles where positional accuracy is paramount.
Choosing the 4206 ensures long-term operational reliability and minimizes costly downtime in demanding industrial environments. Manufactured to stringent quality standards (P5 or better), this bearing offers optimized contact angles and internal geometry, resulting in low friction operation and excellent heat dissipation, thereby extending lubricant life. Its exceptional dynamic load rating (Cr > 24.5 kN) positions the 4206 as the preferred high-performance solution for OEMs and MRO professionals seeking uncompromised durability and precision in heavy-duty machinery.
