When it comes to high-speed applications, choosing the right type of ball bearing is crucial for ensuring optimal performance and reliability. Two of the most commonly used types are guľkové ložiská s hlbokou drážkou and angular contact ball bearings. Each has its own unique characteristics and advantages, making them suitable for different scenarios. In this article, we will delve into the specifications, types, uses, and sizes of guľkové ložiská s hlbokou drážkou, and compare them with angular contact ball bearings to determine which one is better suited for high-speed applications.

Understanding Deep Groove Ball Bearings 

guľkové ložiská s hlbokou drážkou are the most representative structure among rolling bearings and have a wide range of applications. The raceway located on the inner and outer rings has a radius arc cross-section slightly larger than the radius of the rolling ball. This design allows them to bear radial loads and axial loads in two directions. They are available in various types, including open type, steel plate dust covers, rubber sealing rings, or stop rings attached to the outer diameter of the outer ring. For example, the guľkové ložiská s hlbokou drážkou listed include models like 6011-RZ, 6011-2RZ, and 6012, each with different dimensions, load ratings, and limiting speeds.

• Uses and Applications
•  

guľkové ložiská s hlbokou drážkou are highly versatile and are used in a variety of industries. Their low friction torque makes them ideal for applications that require high-speed rotation, low noise, and low vibration. They are commonly found in machinery, automotive, aerospace, and industrial equipment. For instance, in machinery, these bearings are used in electric motors, gearboxes, and conveyor systems. In the automotive industry, they are used in wheel hubs, steering systems, and transmission systems. Their ability to handle both radial and axial loads makes them suitable for a wide range of applications.

• Sizes and Dimensions
•  

The sizes of guľkové ložiská s hlbokou drážkou vary widely to meet different requirements. The dimensions include the outer diameter (D), inner diameter (d), width (B), and other parameters. For example, the 6011-RZ bearing has an outer diameter of 90 mm, an inner diameter of 55 mm, and a width of 18 mm. The basic load rating and limiting speeds also differ among models. The 6011-RZ has a basic load rating of 30.3 kN and a limiting speed of 7000 rpm for grease lubrication.

Comparing Deep Groove Ball Bearings and Angular Contact Ball Bearings 

While guľkové ložiská s hlbokou drážkou can handle both radial and axial loads, angular contact ball bearings are specifically designed to handle higher axial loads. Angular contact ball bearings have a higher load capacity in one direction due to their design, which includes a contact angle. This makes them more suitable for applications where high axial loads are present. However, guľkové ložiská s hlbokou drážkou can still handle significant axial loads, especially when the radial clearance is increased.

• Speed and Performance
•  

In terms of speed, guľkové ložiská s hlbokou drážkou generally have higher limiting speeds compared to angular contact ball bearings. This is because their design allows for smoother rotation and lower friction. For example, the 6012 bearing has a limiting speed of 6700 rpm for grease lubrication, which is relatively high. Angular contact ball bearings, on the other hand, may have lower limiting speeds due to their contact angle, which can cause higher friction at high speeds.

• Noise and Vibration
•  

guľkové ložiská s hlbokou drážkou are known for their low noise and vibration characteristics, making them ideal for applications where precision and quiet operation are required. Their design allows for even load distribution, reducing the chances of noise and vibration. Angular contact ball bearings can also operate quietly, but their performance may vary depending on the load and speed conditions.

FAQ：About Guľkové ložiská s hlbokou drážkou 

What are the advantages of deep groove ball bearings? 

guľkové ložiská s hlbokou drážkou offer several advantages, including their ability to handle both radial and axial loads, low friction, and high-speed capabilities. They are also available in a wide range of sizes and types, making them suitable for various applications.

How do I choose the right deep groove ball bearing for my application? 

When choosing a guľôčkové ložisko s hlbokou drážkou, consider factors such as load requirements, speed, noise and vibration levels, and operating environment. Refer to the specifications and dimensions provided by the manufacturer to ensure the bearing meets your needs.

What is the difference between open and sealed deep groove ball bearings?

Open guľkové ložiská s hlbokou drážkou allow for easy inspection and maintenance but may require additional protection against contaminants. Sealed bearings, on the other hand, are protected against dust and moisture, reducing the need for frequent maintenance.

Can deep groove ball bearings be used in high-temperature applications? 

While guľkové ložiská s hlbokou drážkou are generally suitable for a wide range of temperatures, their performance may vary depending on the specific application. It is important to choose the appropriate lubricant and materials to ensure optimal performance in high-temperature environments.
