SKF 6304 NR Single Row Deep Groove Ball Bearing- Open Type 20mm I.D, 52mm O.D

SKF High Temperature Deep Groove Ball Bearing

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
