SKF Ball Bearings are designed to deliver increased reliability, reduced complexity and decreased environmental impact in high operating temperatures.
Features
Excellent performance in hot conditions, dry environments and low rotational speed applications
Temperature range -30°C to 150°C
Suitable for high and very high speeds
Steel/Ceramic ball material
Plain race type
Low friction
Available in many designs, variants and sizes
Why choose Deep Groove Ball Bearings?
For their versatility - channelling radial and axial loads they are widely used in many industries
Cost efficient - due to low friction torque the temperature remains low therefore reduces the energy cost of running in equipment such as the conveyor belt
Low maintenance - no additional lubrication after installation
Applications
Agricultural industry
Food processing
Machine Tools
Material handling
Medical/Pharmaceutical
Printing
Wind energy
