Product Description
The 6211-2Z/VA201 SKF High Temperature Ball Bearing is a precision-engineered solution designed for extreme operating environments, offering exceptional performance and reliability in challenging thermal conditions.
Key Technical Specifications
- Bore Diameter: 55mm
- Outside Diameter: 100mm
- Width: 21mm
- Temperature Range: -40°C to +250°C
Advanced Design Features
- Single row deep groove ball bearing configuration
- No filling slots for enhanced structural integrity
- Large radial internal clearance (4x standard C5 clearance)
- Prevents seizing during rapid temperature changes
- Capable of handling moderate axial and radial loads
Surface and Protection Characteristics
- Entire bearing surface manganese phosphated
- Superior corrosion resistance
- Improved running and operational properties
- Protective shields on both sides to prevent contaminant ingress
- Durable pressed steel cage
Lubrication System
- Lubricated with polyalkylene glycol/graphite mixture
- Double the lubricant quantity compared to open VA201 design
- At temperatures above +200°C, transitions to dry lubrication
Typical Applications
- Industrial ovens and high-temperature manufacturing equipment
- Steel processing machinery
- Dryers and thermal processing units
- Chemical processing plants
- Aerospace and automotive high-temperature environments
- Kiln and ceramic manufacturing machinery
Note: This SKF high-temperature ball bearing is specifically designed to maintain performance and structural integrity in extreme temperature conditions where standard bearings would fail, offering engineers and maintenance professionals a robust solution for demanding operating environments.
