SKF 6302 TN9 C3 15x42x13 Deep Groove Ball Bearing

Optimized for High-Speed Electric Motor Applications

The SKF 6302 TN9 C3 is a premium deep groove ball bearing engineered for applications operating at elevated speeds and temperatures. Unlike standard deep groove ball bearings, this version combines a reinforced TN9 polyamide cage with increased C3 internal clearance, making it particularly suitable for electric motors, pumps, industrial drives and continuously operating machinery.

The combination of SKF manufacturing quality, optimized internal geometry and lightweight cage construction delivers excellent running accuracy, reduced friction and extended service life in demanding industrial environments.

Application in Industrial Systems

SKF 6302 TN9 C3 is commonly used in:

• electric motors
• industrial pumps
• ventilation systems
• compressors
• industrial gearboxes
• conveyor systems
• agricultural machinery
• production equipment
• industrial automation systems
• OEM machinery

The increased internal clearance allows stable operation when thermal expansion occurs during continuous-duty service.

Construction and Design

SKF 6302 TN9 C3 is a single-row deep groove ball bearing featuring:

• open bearing design
• reinforced TN9 polyamide cage
• C3 increased radial internal clearance
• precision-machined raceways
• optimized ball guidance system
• cylindrical bore

The TN9 cage reduces weight and rolling resistance while maintaining excellent stability at high rotational speeds. The C3 clearance helps compensate for shaft and housing expansion during operation.

FAQ

What does TN9 mean in SKF bearings?

TN9 indicates a glass-fiber reinforced polyamide cage designed to reduce friction and improve high-speed performance.

Why is C3 clearance important?

C3 internal clearance provides additional space between rolling elements and raceways, allowing reliable operation at higher temperatures and speeds.

Is SKF 6302 TN9 C3 suitable for electric motors?

Yes. This bearing is commonly used in electric motors because the TN9 cage and C3 clearance help accommodate thermal expansion.

Does this bearing contain seals?

No. SKF 6302 TN9 C3 is an open bearing intended for systems with external lubrication or protected housings.

What loads can SKF 6302 TN9 C3 support?

The bearing supports radial loads and moderate axial loads acting in both directions.
