SKF C 2207 KTN9/C3 Self-Aligning Toroidal Roller Bearing

Technical Specifications & Construction

The SKF C 2207 KTN9/C3 is a self-aligning toroidal roller bearing designed for industrial applications requiring high load capacity and motion reliability. With an inner diameter of 35 mm, an outer diameter of 72 mm and a width of 23 mm, this bearing offers a robust foundation for machinery. It belongs to SKF’s CARB™ line, which combines the benefits of cylindrical and spherical roller bearings: angular displacement compensation, axial displacement accommodation and high radial load capability. The ‘KTN9’ designation refers to the reinforced cage (glass-fiber-reinforced polyamide) and the ‘C3’ suffix indicates an increased internal clearance, allowing higher speeds and improved performance under thermal or misalignment stress.

Industrial Applications & Advantages

Designed for demanding industrial applications, this bearing excels in gearboxes, heavy drives, conveyors, rotating shafts, and other equipment where standard bearings fail due to shaft misalignment or axial movement. Search phrases frequently used by engineering procurement include: “toroidal roller bearing 35x72x23”, “SKF C2207 KTN9 C3 bearing”, “self-aligning CARB bearing”, “industrial toroidal bearing 35 mm”.
Key benefits:

• Self-alignment capability reduces stress from shaft bend or misalignment, extending service life.

• Higher load capacity for its size due to the toroidal roller geometry.

• Reduced maintenance & downtime thanks to stronger design and precision manufacturing.

• Standard dimension (35x72x23 mm) facilitates seamless replacement and parts interchange in periods of production uptime.

FAQ

Q: What does “C3” clearance indicate?
A: It signifies increased internal clearance beyond standard, enabling better performance under high speed, high temperature or minor misalignment.

Q: Can this bearing compensate for shaft misalignment?
A: Yes. The CARB design allows angular and axial displacement, so misalignment or shaft deflection has less impact on bearing life.

Q: What load types is this bearing suitable for?
A: It is optimized for radial loads and moderate axial loads, especially in heavy industrial machinery where load sharing and high reliability are essential.

Q: Are 35x72x23 mm bearings common in industrial use?
A: Yes. This standard size supports many industrial shafts and reduces parts-inventory complexity, making it ideal for replacements and standardization.
