SKF Needle Roller Bearing, 20mm Inside Diameter, 28mm Outside Diameter - NK 20/20
This needle roller bearing is designed for enhanced performance in various mechanical applications. Featuring a 20mm inside diameter and a 28mm outside diameter, it is a high-load needle roller bearing constructed from durable steel. This product is notable for its compact dimensions and lightweight design, making it an ideal choice for space-constrained setups in automation and machinery.
Features & Benefits
• Dynamic load rating of 16.5 kN allows for reliable operation
• Reference speed of 19,000 r/min ensures efficient performance
• Limiting speed of 22,000 r/min optimises machinery function
• Designed without an inner ring for maximum efficiency
• Made from steel for durability in demanding conditions
Applications
• Used for high-performance in automation systems
• Ideal for rotary requiring minimal radial space
• Suitable for mechanical systems with constrained design options
• Effective in electric motors and various industrial machinery
What are the benefits of using this design without an inner ring?
The absence of an inner ring allows for a more compact assembly, freeing up space for other components, which is particularly beneficial in systems where space is limited. This design also contributes to reduced weight and enhances the overall efficiency of the assembly.
How does the static load rating influence selection?
A static load rating of 25.5 kN indicates the capacity of the bearing to withstand external forces when stationary, which is crucial for applications where the bearing may be subjected to heavy loads during rest periods.
What factors should be considered when determining the operational limits?
Considerations should include the dynamic and static load ratings, reference and limiting speeds, and the thermal environment in which the bearing will operate. Additionally, compatibility with lubricants and shaft tolerances is essential for optimal performance.
