SKF Needle Roller Bearing, 40mm Inside Diameter, 12mm Race Width - HK 4012

This needle roller bearing is a precision component designed for various mechanical applications. With an inside diameter of 40mm and a race width of 12mm, this bearing provides efficient support for rotary movements. The open end type and metal construction ensure durability and reliable performance in demanding environments.

Features & Benefits

• Static load rating of 24.5kN enhances strength under heavy loads
• Dynamic load rating of 13.4kN for reliable long-term performance
• Sheet steel cage optimises roller guidance and reduces friction
• Parallel bore type for easy fitting in standard assemblies
• Minimal radial space required due to compact design

Applications

• Utilised in automation systems requiring precise rotary motion
• Suitable for electric motors that demand high-speed capabilities
• Ideal for machinery in mechanical industries with tight tolerances
• Effective in various electrical equipment for improved efficiency

What are the limiting factors regarding speed for this component?

The maximum speed for grease lubrication is 5000r/min, while oil lubrication allows for a higher limit of 7000r/min.

How does the material used affect its performance?

The metal construction provides strength and durability, allowing for high load capacities and reducing wear in demanding applications.

What maintenance considerations should be taken into account?

Regular inspection and proper lubrication are essential to ensure optimal performance and longevity, avoiding overheating and wear over time.

What is the importance of the fatigue load limit?

The fatigue load limit of 2.8kN signifies the maximum load under which the bearing can operate without sustaining damage over repeated uses, which is important for long-lasting applications.

How can this bearing contribute to energy efficiency in machinery?

Its low friction design helps improve energy efficiency by minimising power loss in mechanical systems.
