Double row self-aligning ball bearings are precision components designed to accommodate misalignment between the shaft and housing, reducing friction and wear in industrial machinery. Their dual-row ball arrangement provides higher load capacity and stability compared to single-row bearings. Commonly used in applications like conveyors, pumps, and agricultural equipment, these bearings excel in environments with shaft deflection or mounting errors. The self-aligning feature allows ±3° angular misalignment compensation, ensuring smooth operation even under challenging conditions. Materials typically include chrome steel for durability, with optional seals or shields for contamination protection.
