Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

SKF, the Swedish manufacturer, is renowned for producing high-quality original bearings that are used in a wide range of applications due to their precision, durability, and reliability. Here's a detailed introduction to SKF original bearings:

1. Design Features:

• SKF bearings are designed with specific features that limit their use in various applications. These features include tapered bores, shields or seals, and self-aligning capabilities. Tapered bore bearings are available for certain types with an inner ring bore that is larger on one side than the other, typically a 1:12 taper. Shields or seals significantly increase the service life of bearings in contaminated applications. Self-aligning bearings, patented by SKF, are chosen for applications with high dynamic misalignment.

2. Historical Development:

• SKF has been a significant force in the evolution of cylindrical roller bearings. In 1909, Dr.-Ing. Josef Kirner patented the modern cylindrical roller bearing, which had crowned raceways to avoid damaging edge stresses at the roller ends. SKF acquired shares of Norma Compagnie GmbH in 1914, and since then, the development of single-row cylindrical roller bearings has been intertwined with SKF.

3. Improvements and Milestones:

• In the 1930s, SKF was instrumental in standardizing the boundary dimensions of cylindrical roller bearings, making them identical to those of standard ball bearings. The 1960s saw the introduction of E-type bearings, which optimized the bearing cross-section and increased load-carrying capacity by an average of 35%.

• The 1980s brought the introduction of logarithmic profiles for roller raceways, optimizing load distribution and reducing the risk of edge stresses. The new millennium marked the introduction of SKF Explorer cylindrical roller bearings, which featured extremely clean and homogenous steel, new heat-treatment procedures, and upgraded manufacturing processes.

4. Performance and Endurance:

• SKF Explorer bearings set new standards with respect to performance and endurance, offering up to three times longer service life than previous standards. They have an enhanced ability to support dynamic loads and are superior to all other conventional cylindrical roller bearings.

5. General Bearing Specifications:

• SKF bearings adhere to international standards such as ISO 15 for boundary dimensions and ISO 492 for tolerances. They also follow ISO 5753-1 for internal clearance. The permissible misalignment for SKF bearings is approximately 2 to 10 minutes of arc, which increases bearing noise and reduces service life when exceeded.

6. Applications:

• SKF original bearings are used in a variety of applications, from consumer devices like skateboards to large rotating equipment such as cement kilns. They are chosen for their ability to handle combined loads, such as in centrifugal pumps, which experience both radial and axial loads.

7. Product Range:

• SKF offers a broad range of bearings, including deep groove ball bearings, spherical roller bearings, and cylindrical roller bearings, each with specific performance characteristics and applications.

SKF original bearings are recognized for their high performance, long service life, and the ability to operate under various conditions. Their continuous innovation and commitment to quality make SKF a leading choice for bearings in industrial and mechanical applications worldwide.
