SKF 2208 ETN9/C3 40 mm ID 2 Row Self-Aligning Ball Bearing -, 80 mm OD

This self-aligning ball bearing is designed to accommodate shaft misalignment while supporting rotational components in industrial equipment. It combines dual-row rolling elements with a cylindrical inner bore and an open end to provide continuous operation in assemblies where alignment can shift during use. Suitable for high-speed applications, it is built with steel rolling elements and a non-metallic cage to balance durability with reduced friction.

• Non-metallic cage reduces friction and lowers maintenance needs
• C3 internal clearance compensates for thermal expansion during operation
• 31.9 kN dynamic load capacity supports heavy radial loads
• 10 kN static load capacity resists shock and standstill loads
• Rated to 11,000 r/min for high-speed rotation
• Two-row arrangement allows self-correction of shaft misalignment

• Suitable for conveyor drive shafts in manufacturing lines
• Ideal for motor and gearbox input shafts in automation
• Used with rotary assemblies in electronics manufacturing equipment
• Can be used for pivoting joints in mechanical handling systems

It features a cylindrical bore that accepts plain shafts and can be mounted with appropriate interference or adaptor fittings depending on the application.

The bearing’s construction supports sustained operation up to 11,000 r/min, with the internal clearance providing tolerance for thermal and speed-induced dimensional changes.

The balls are fabricated from steel for load-bearing contact, while the retainer is MADE from a non-metallic material to reduce drag and noise.

The dual-row spherical seating of the outer ring allows the inner ring to tilt slightly, accommodating angular misalignments without compromising rolling action.
