• 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 ball bearing is a robust single row deep groove design, specifically engineered for high performance in various mechanical applications. With an inside diameter of 40mm and an outside diameter of 90mm, it provides a reliable solution for scenarios requiring both durability and efficiency. Featuring a race width of 23mm and shielded on both sides, this bearing is a versatile option for many industries.

• Single row design minimises friction for smooth operation
• Shielded on both sides to protect against contaminants
• C3 bearing clearance accommodates thermal expansions
• High static load rating of 24kN enables heavy load support
• Dynamic load rating of 42.3kN ensures superior performance
• Constructed from steel for enhanced durability and longevity

• Utilised in industrial automation systems for efficient rotation
• Commonly found in electrical appliances for stable performance
• Applied in mechanical assemblies requiring reliable load handling
• Implemented in conveyor systems for smooth operations

The C3 clearance indicates a greater internal space, accommodating thermal expansions during operation, which helps maintain performance even under varying temperatures.

The shielded design prevents dust and debris intrusion, prolonging service life and reducing maintenance needs by limiting contamination that could affect performance.

This product possesses a basic dynamic load rating of 42.3kN and a static load rating of 24kN, making it suitable for applications with significant load requirements.

The reference speed for optimal operation is 17,000 r/min, while the limiting speed is capped at 8,500 r/min, ensuring reliable functioning within these parameters.
