SKF Deep Groove Ball Bearing, 90mm Inside Diameter, 160mm Outside Diameter - 6218


This deep groove ball bearing is engineered for optimal performance in various applications. Designed with an inner diameter of 90mm and an outer diameter of 160mm, it accommodates high load capacities. This single-row ball bearing features an open-type design, allowing for easy maintenance and enhanced lubrication access. Composed of durable steel, it provides reliability in demanding industrial environments.

Features & Benefits


• Open-type structure allows for flexible maintenance options
• Steel construction enhances strength and wear resistance
• Calculated reference speed of 8500 rpm for improved efficiency
• Lightweight design at 2.216kg simplifies installation and handling

Applications


• Used in automation systems requiring reliable rotation
• Suitable for electrical machinery and motor
• Ideal for mechanical equipment in manufacturing processes
• Utilised in assembly line robotics for smooth operation

What are the implications of using this bearing in high-speed applications?


The bearing's reference speed of 8500 rpm indicates that it can operate efficiently at high speeds, making it suitable for applications where quick rotation is crucial. The open-type design further enhances lubrication, reducing the risk of overheating.

How does its construction impact its overall performance in demanding environments?


The steel material of the bearing provides robust performance under various load conditions while maintaining dimensional stability. This construction makes it less prone to wear, thereby extending the bearing's operational life in tough industrial settings.

What benefits does the open-type design offer over sealed alternatives?


The open-type design allows for easier access to lubrication points, facilitating maintenance and reducing downtime. This feature is beneficial when regular servicing is necessary to ensure smooth operation, especially in environments where dust and debris are minimal.

Can you explain how the load ratings affect the bearing's application?


The static load rating of 73.5 kN and dynamic load rating of 101 kN indicate that the bearing can support significant forces, making it ideal for applications where heavy loads are prevalent. Choosing a bearing with appropriate load ratings is essential to prevent premature failure in critical applications.
