SKF Bearings 3308A/C3 Bearing
The SKF 3308A/C3 is a high-performance double row angular contact ball bearing engineered for applications requiring high radial and axial load capacity in both directions. Featuring a 40mm bore, 90mm outside diameter, and a 1.4375" width, this unit utilizes a 30-degree contact angle to provide a rigid bearing arrangement capable of handling tilting moments. The C3 internal clearance is critical for HVACR high-speed shafts and motors, allowing for thermal expansion without risking premature seizure or excessive friction. Built with an open closure design and a robust metal cage, this angular contact bearing ensures optimal lubricant circulation in oil-mist or grease-bathed environments. Technicians often specify SKF 3308 series bearings for pump assemblies and compressors where axial displacement must be strictly controlled. The precision-engineered raceways minimize vibration and heat generation, ensuring long-term reliability in demanding industrial drive systems.
Key Benefits for Technicians- Enhanced Load Distribution: The double-row configuration supports significant bidirectional thrust loads, ideal for heavy-duty fan and pump applications.
- C3 Radial Clearance: Optimized for high-temperature operating environments, preventing internal preloading during thermal expansion of the shaft.
- 30-Degree Contact Angle: Increases the stiffness of the bearing arrangement, reducing shaft deflection and improving overall system alignment.
- Steel Cage Construction: Provides superior durability and heat resistance compared to polyamide cages, suitable for high-friction industrial cycles.
- Standardized Metric Dimensions: Ensures direct compatibility for drop-in replacement in 40mm shaft assemblies without the need for housing modifications.
Does the SKF 3308A/C3 require manual lubrication?
Yes, as an open closure bearing, it requires an external lubrication source, typically through an oil bath or grease fittings, to maintain optimal performance and heat dissipation.
Is the C3 clearance appropriate for standard commercial motors?
C3 clearance is specifically designed for applications where the housing may be cooler than the shaft, or where high speeds generate internal heat that would tighten a standard clearance bearing.
Can this bearing handle pure radial loads?
While it excels at combined loads, it is highly effective for pure radial loads; however, a minimum load is required to ensure the balls rotate correctly without skidding on the raceways.
