• 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

This deep groove ball bearing is designed to excel in various applications where reliability and performance are essential. With an inside diameter of 20mm and an outside diameter of 47mm, it fits well in constrained spaces and has a race width of 14mm. Featuring a single row configuration for efficient load management.

• Both sides sealed to enhance durability and protect against contamination
• Steel construction ensures robust performance under high load conditions
• Rated static load of 6.55kN supports heavy machinery requirements
• High dynamic load capacity of 13.5kN for reliable rotation
• Designed with CN clearance for optimal performance in various axial and radial loads
• Compact deep groove design suitable for limited space requirements

• Used for Precision machinery fittings in automation equipment
• Suitable for Electrical motor assemblies where high-speed operation is required
• Ideal for mechanical devices requiring long-lasting performance
• Recommended for industrial ball bearings in manufacturing environments

The seals on both sides prevent dirt and moisture ingress, significantly enhancing the bearing's lifespan and operational reliability even in harsh environments.

The dynamic load rating of 13.5kN allows the bearing to efficiently handle substantial ongoing loads during operation, making it ideal for machinery that operates under heavy stress.

The steel material can withstand moderate temperatures, but for extreme conditions, it is advisable to evaluate the lubrication method and operating limits.

The CN clearance offered is suitable for general applications, balancing the fit and function while accommodating regular movements between the shaft and housing.

Yes, the standard dimensions and design facilitate easy replacement with minimal adaptations necessary in existing setups.
