SKF Self-aligning ball bearings Series Ball Bearing, 45mm Inside Diameter, 100mm Outside Diameter - 1309 ETN9/C3


This ball bearing is a self-aligning unit designed to accommodate shaft misalignment while supporting radial and light axial loads in rotating machinery. It integrates two concentric rows of steel balls within an open assembly to permit angular displacement and smooth operation at elevated rotational speeds, making it suitable for applications where alignment variation and continuous rotation occur.

Features and Benefits:


• Two rows provide enhanced load distribution for longer service life
• C3 internal clearance permits thermal expansion without seizure
• Non-metallic cage reduces friction and limits noise generation
• Steel balls offer Durable rolling contact under cyclic loading
• Open end design facilitates inspection and lubrication access

Applications


• Suitable for conveyors experiencing shaft deflection
• Ideal for pumps operating at sustained high speeds
• Used with agricultural machinery subject to angular misalignment
• Can be used for industrial fans with frequent start-stops
• Appropriate for gearboxes requiring accessible bearings

What is the allowable rotational speed for this bearing?


It is rated for continuous operation up to 8,500 r/min.

What load capacities can this bearing support?


The dynamic capacity is 39 kN and the static capacity is 13.4 kN.

How do the bore and outer dimensions affect mounting?


The bore is 45 mm and the outside diameter is 100 mm, so shafts and housings must match these dimensions for correct seating.

Which raceway and width characteristics are relevant to assembly?


The bearing has a cylindrical bore and a race width of 25 mm, requiring compatible housing fits and axial space.
