SKF 1208 EKTN9/C3 40 mm ID 2 Row Ball Bearing -, 80 mm OD

This ball bearing is a self-aligning, double-row component designed to accommodate shaft misalignment while supporting radial loads in rotating assemblies. It features an open-end design with steel balls and a tapered bore for secure mounting on conical shaft seats. The bearing is intended for applications requiring moderate static and dynamic load capacity and suitability at elevated rotational speeds.

• C3 internal clearance reduces operating friction for thermal expansion
• 11,000 r/min limiting speed permits high-speed rotation
• 19.9 kN dynamic load capacity sustains heavy radial forces
• 6.95 kN static rating resists deformation under standstill loads
• Non-metallic cage lowers noise and decreases wear
• Tapered bore eases axial positioning on shafts

• Suitable for tapered-bore double-row ball bearing for shafts in drives
• Ideal for equipment needing 40x80x18 self-aligning ball bearing form factor
• Used with rotating machinery that demands high-speed 11,000 r/min self-aligning bearing operation
• Can be used for assemblies requiring open-end self-aligning ball bearing 80 mm OD mounting
• Used for systems needing 40 mm bore tapered inner-ring bearing seating

The tapered inner ring enables axial position control during installation by using a tapered sleeve or nut to achieve a secure interference fit on the shaft.

The dual-row configuration increases radial load capacity and improves alignment tolerance compared with single-row designs, helping to maintain contact under misalignment.

A non-metallic cage reduces friction and acoustic emissions while offering compatibility with lubrication regimes to decrease wear rates.

The static load rating quantifies the bearing's capacity to withstand applied loads without permanent shape change when stationary, guiding selection for press-fit or heavy-load stop conditions.
