Product Description
The 6308-2Z/VA208 SKF High Temperature Ball Bearing is a precision-engineered solution designed for extreme operating environments, offering exceptional performance in challenging thermal conditions.
Key Technical Specifications
- Dimensions: 40mm x 90mm x 23mm
- Temperature Range: -150°C to +350°C
- Design: Single row deep groove ball bearing
- Bore Size: 40mm
- Configuration: Shielded (2Z)
Advanced Engineering Features
- Large radial internal clearance (4x standard C5 clearance) prevents seizing during rapid temperature changes
- Manganese phosphated surfaces provide superior corrosion protection and improved running properties
- Innovative segmented graphite cage design for self-lubrication
- Two protective shields prevent solid contaminant ingress
- Environmentally friendly with zero dangerous gas emissions
- Capable of accommodating moderate axial and radial loads
Unique Lubrication Technology
The specialized graphite cage releases minute quantities of lubricant during rotation, ensuring consistent performance in high-temperature applications without external lubrication.
Ideal Applications
- Industrial ovens and kilns
- High-temperature manufacturing equipment
- Steel processing machinery
- Chemical processing plants
- Aerospace and automotive high-stress environments
- Industrial machinery operating in extreme temperature conditions
- Equipment requiring reliable performance under thermal stress
Typical performance advantages include sustained operational reliability, minimal maintenance requirements, and exceptional thermal stability across diverse industrial settings. The 6308-2Z/VA208 offers unparalleled performance in environments where standard bearings would quickly fail.
