precision chrome steel deep groove ball bearing

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

Precision chrome steel deep groove ball bearings are engineered for high performance and reliability in various industrial applications. Here's a detailed introduction:

1. Material and Hardness:

• These bearings are made from high-quality chrome steel, such as GCr15 or 52100 grade, which is known for its durability and ability to handle heavy loads without deformation. The steel is heat treatable, maintaining a high level of strength when hardened, which is crucial for withstanding the demands of high-speed operations and heavy loads.

2. Corrosion Resistance:

• While not as corrosion-resistant as stainless steel, chrome steel bearings form a protective oxide layer that helps resist rust in moderate conditions, making them suitable for a wide range of applications where both strength and limited corrosion resistance are needed.

3. Wear Resistance:

• The hardness of chrome steel contributes to its excellent wear resistance, even under high-stress conditions. This feature makes chrome steel deep groove ball bearings ideal for components exposed to repeated friction, such as in industrial machinery.

4. Applications:

• Precision chrome steel deep groove ball bearings are widely used in industries like automotive, aerospace, and industrial machinery due to their ability to handle high loads and minimize friction. They are also used in applications such as aircraft models, remote control cars, machine tools, motors, pumps, agricultural machinery, and more.

5. Design and Construction:

• These bearings typically consist of an outer ring, an inner ring, and rolling elements (balls). The deep groove design provides a large area for the balls to roll, reducing friction and allowing for high-speed rotation. The precision manufacturing process ensures that the bearing rings and balls are of the same base material, often with ceramic balls available for hybrid ball bearings.

6. Tolerance and Accuracy:

• Precision chrome steel deep groove ball bearings are available in various tolerance classes, from ABEC-1 (P0) to ABEC-7, which indicates the level of precision and the amount of allowable variation in size. This allows for precise fit and operation in applications requiring high accuracy.

7. Sealing and Lubrication:

• These bearings can be sealed with double shields (ZZ), single shield (RS), or open types, providing protection against contaminants and retaining lubricant. The choice of lubricant, such as SRL, SB-M, ET-K, or Super N, can also be customized based on specific application needs.

8. Speed and Performance:

• The maximum speed for these ball bearings is limited by mechanical and kinematic criteria, and special measures regarding lubrication and cage design can enhance speed limits. They are designed to operate at high speeds, making them suitable for high-speed electric machinery, printing machinery, and other high-speed applications.

In summary, precision chrome steel deep groove ball bearings offer a combination of high load capacity, speed, and precision, making them a popular choice for a variety of precision applications where reliability and performance are critical.
