SKF 2212 EKTN9/C3 60x110x28 mm Self Aligning Ball Bearing

Design and Construction

SKF 2212 EKTN9/C3 is a double row self aligning ball bearing designed to operate reliably in applications exposed to shaft misalignment and housing deflection. Within the category of SKF self aligning ball bearings, this model represents a medium size solution optimized for dynamic industrial systems.

The bearing features two rows of balls running in a common spherical outer ring raceway. This geometry allows automatic angular adjustment of the inner ring relative to the outer ring, reducing stress caused by mounting inaccuracies.

The EKTN9 designation indicates a glass fiber reinforced polyamide cage, ensuring reduced weight, lower friction and stable ball guidance at higher speeds. The C3 internal clearance provides increased radial clearance, recommended for elevated operating temperatures or tighter interference fits. The tapered bore 1:12 enables mounting on an adapter sleeve for flexible shaft configurations.

Industrial Applications

SKF 2212 EKTN9/C3 60x110x28 mm is commonly used in:

• Industrial gearboxes

• Centrifugal and axial fans

• Process pumps

• Conveyor systems

• Agricultural machinery

• Power transmission assemblies requiring misalignment compensation

This 60 mm bore variant is particularly effective in systems where moderate radial loads and occasional axial loads occur simultaneously.

Main Description

SKF 2212 EKTN9/C3 60x110x28 mm is a double row self aligning ball bearing with tapered bore, engineered to compensate shaft misalignment while operating under dynamic radial loads.

As part of the SKF 2212 series, this bearing strengthens the self aligning ball bearings category by delivering reliable performance in medium duty industrial environments. The spherical outer raceway allows the bearing to realign automatically, minimizing internal stress and preventing premature wear.

The 60x110x28 mm configuration is widely selected for industrial fans, mid size gear units and pump drives. The C3 internal clearance ensures thermal stability when operating temperatures rise, while the EKTN9 polyamide cage reduces friction and enhances rotational efficiency.

The tapered bore version provides installation flexibility, particularly when used with adapter sleeves, allowing easier mounting, dismounting and internal clearance adjustment. In maintenance intensive environments, this feature significantly reduces downtime.

For maintenance departments and OEM system integrators, SKF 2212 EKTN9/C3 offers a balance between misalignment tolerance, operational durability and predictable long term performance.
