Key Features and Advantages
- High Load Capacity: Capable of withstanding extremely heavy axial loads and moderate radial loads, making it ideal for heavy machinery, gearboxes, and vertical shaft applications.
- Self-Aligning Capability: The spherical design allows for angular misalignment (up to 2°), compensating for shaft deflections and mounting errors.
- SKF Explorer Performance: Incorporates SKF’s premium Explorer technology, delivering enhanced fatigue life, reduced friction, and improved operational efficiency compared to standard bearings.
- Robust Construction: The sheet steel cage ensures durability and maintains roller spacing for consistent performance under high speeds and loads.
- Cost-Effective Reliability: Engineered for long service life with minimal maintenance, reducing total operational costs in industrial settings.
Typical Applications
- Heavy-duty gearboxes and reducers
- Vertical electric motors and generators
- Presses and rolling mills
- Wind turbine main shafts
- Marine propulsion systems
- Mining and construction equipment
Installation and Maintenance Tips
- Mount with proper shaft and housing fits (standard tolerance class P0) to prevent excessive clearance or preload.
- Ensure correct axial load application (minimum load factor A=0.11) to avoid roller skidding and premature wear.
- Use recommended lubricants (grease or oil) compatible with operating temperatures and speeds; re-lubricate per SKF guidelines for extended service life.
- Follow SKF’s mounting procedures, including clean workspaces, proper heating/cooling for interference fits, and accurate alignment checks.
