The 6406-2RS is a Sealed Deep Groove Ball Bearing from the robust 64 series, engineered to handle substantial radial and moderate axial loads while providing built‑in contamination resistance. Its double rubber seals (2RS) effectively retain grease and block dust, moisture, and debris, making it a reliable choice for harsh operating conditions. With a 30 mm bore, 90 mm outer diameter, and 23 mm width, this bearing is widely specified in heavy machinery, industrial gearboxes, pumps, and agricultural equipment where durability and low maintenance are critical.
