Key Features and Advantages
- High-Speed Capability: Engineered for reliable operation at high rotational speeds, making it suitable for applications like machine tool spindles and high-speed gearboxes.
- Optimized Load Handling: The 40° contact angle provides excellent axial load capacity while maintaining good radial load handling capabilities.
- SKF Explorer Technology: Incorporates advanced material science and manufacturing processes for extended fatigue life, reduced friction, and improved operational efficiency compared to standard bearings.
- Robust Brass Cage: Machined brass cage ensures precise roller guidance, high-temperature resistance, and long service life under heavy loads.
- Universal Matching: Designed for duplex arrangements (back-to-back, face-to-face, or tandem) to achieve specific preload levels and enhance rigidity.
- P6 Precision Tolerance: Ensures accurate positioning and reduced vibration in precision applications.
Typical Applications
- Machine tool spindles and rotary tables
- High-speed gearboxes and reducers
- Centrifugal pumps and compressors
- Gas and steam turbines
- Electric motors and generators
- Printing and textile machinery
Installation and Maintenance Tips
- Mounting Arrangements: Ideal for duplex mounting (DB, DF, or DT configurations) to accommodate bidirectional axial loads or increase rigidity.
- Preload Considerations: Select appropriate preload grade (GA, GB, GC) based on application requirements for optimal performance.
- Lubrication: Use high-quality lubricants (grease or oil) compatible with operating speeds and temperatures; follow SKF's lubrication guidelines for re-lubrication intervals.
- Shaft and Housing Fits: Adhere to recommended seat tolerances for standard conditions to ensure proper bearing operation and prevent excessive clearance or preload.
- Alignment: Ensure proper shaft and housing alignment to avoid premature wear and extend bearing life.
