The SKF 3304ATN9C3 is a genuine double row angular contact ball bearing designed for applications requiring high radial and axial loads. Featuring a 20mm bore, 52mm outer diameter, and 22.2mm width, this bearing incorporates a glass fibre reinforced polyamide 6,6 cage (ATN9) for reduced friction and noise. It has a C3 internal clearance, indicating a greater than normal radial clearance, suitable for specific operating conditions. With a 25-degree contact angle, it offers robust performance and reliability in various industrial and agricultural machinery.
