The SKF 5308 A-2Z/C3 is a double-row angular contact ball bearing engineered to accommodate high radial and axial loads in both directions. Its design integrates two single-row angular contact ball bearings in a back-to-back arrangement, offering enhanced load-carrying capacity and rigidity.
Key Features
- Double-Row Design: Provides increased load capacity and improved radial and axial stability compared to single-row bearings.
- Metal Shields (2Z): Equipped with steel shields on both sides to protect against contaminants and retain lubrication.
- Increased Internal Clearance (C3): Allows for thermal expansion and accommodates higher speeds, reducing the risk of overheating.
- Steel Cage: Ensures durability and reliable performance under demanding conditions.
Specifications
- Bore Diameter: 40 mm
- Outside Diameter: 90 mm
- Width: 36.5 mm
- Contact Angle: 30°
- Dynamic Load Rating: 64 kN
- Static Load Rating: 44 kN
- Limiting Speed (Oil Lubrication): 6,700 rpm
- Limiting Speed (Grease Lubrication): 5,000 rpm
Applications
This bearing is ideal for applications requiring high load capacity and rigidity, such as:
- Pumps
- Compressors
- Centrifuges
- Gearboxes
- Conveyors
The SKF 5308 A-2Z/C3 bearing’s robust construction and design make it suitable for demanding industrial environments where reliability and performance are critical.
