Deep Groove Ball Bearings

Overview

Deep Groove Ball Bearings

Deep groove ball bearings are named for their deep raceway grooves. They are highly versatile and the most widely used type of bearing. These bearings not only feature low friction but also can handle radial loads and axial loads in both directions. They are easy to install and require less maintenance compared to other types of bearings.

NYZ offers a wide range of deep groove ball bearings, which can be customized to meet your application needs, making them an ideal replacement for well-known brands like SKF, NSK, and KOYO.

Product List

Single Row Deep Groove Ball Bearings

Single Row Deep Groove Ball Bearings

Single-row deep groove ball bearings consist of an inner ring, an outer ring, a single row of rolling elements (usually steel balls), and a cage. The raceways of the inner and outer rings are shaped into deep grooves, which can effectively support and guide the rolling elements.

Features:

  • High Load Capacity:Capable of withstanding a certain degree of bidirectional axial loads, performing well especially at high speeds.

  • High Speed:Due to low rolling friction, these bearings are suitable for high-speed operations, making them widely used in applications requiring high-speed performance.

  • Low Noise and Low Vibration:Manufactured with high precision, these bearings operate with low noise and vibration, ensuring smooth operation of the equipment.

Single row deep groove ball bearings are available in five different designs: standard deep groove ball bearings (open type), ball bearing deep groove with dust covers, deep groove ball bearings with rubber seals, deep groove ball bearings with snap ring grooves, and deep groove ball bearings with snap ring grooves and seals. Each type has its specific application scenarios. Choosing the right type of bearing based on the environment and requirements can ensure the efficient and reliable operation of the equipment.

Double Row Deep Groove Ball Bearings

Double Row Deep Groove Ball Bearings

Double-row deep groove ball bearings are a type of rolling bearing with two rows of balls, designed similarly to two single-row deep groove ball bearings mounted back-to-back. They are particularly suitable for bearing configurations where the load capacity of a single-row deep groove ball bearing is insufficient.

Features:

  • High Load Capacity:Capable of withstanding bidirectional axial loads, increasing the bearing’s application flexibility.

  • High Rigidity:The presence of double rows of balls provides greater rigidity, making the bearing suitable for applications requiring high stiffness.

Stainless Steel Deep Groove Ball Bearings

Stainless Steel Deep Groove Ball Bearings
Stainless steel deep groove ball bearings are deep groove ball bearings made from stainless steel. They offer excellent corrosion resistance and mechanical properties, making them suitable for harsh environments and applications with high hygiene requirements.

Features:

  • Corrosion Resistance:
    Made from high-quality stainless steel (such as AISI 440C, AISI 304, or AISI 316), these bearings offer exceptional corrosion resistance.

  • High Strength and Durability:
    Stainless steel provides excellent mechanical strength and wear resistance.

  • High and Low Temperature Performance:
    Stainless steel materials exhibit good thermal stability, allowing the bearings to operate reliably in both high and low temperature environments.

Stainless steel deep groove ball bearings, due to their excellent corrosion resistance, high strength, durability, and ease of cleaning, are widely used in the food processing, pharmaceutical, chemical, marine, and outdoor equipment industries. They provide reliable performance and long service life in harsh and corrosive environments, meeting the demands of various specialized applications.

FAQs

Deep groove ball bearings are widely used in various industrial and civilian equipment, including motors, automobiles, household appliances (such as washing machines and air conditioners), industrial machinery (such as machine tools, pumps, and compressors), and office equipment (such as printers and copiers). Their high load capacity and low friction characteristics make them suitable for high-speed and high-precision applications.

To extend the service life of deep groove ball bearings, the following maintenance should be performed regularly:

  • Lubrication: Regularly check and replenish the lubricant to maintain proper lubrication.
  • Cleaning: Ensure a clean working environment for the bearings to prevent dust and contaminants from entering.
  • Inspection: Regularly inspect the bearing's operating condition to promptly detect and address any abnormalities, such as noise, vibration, and overheating.
  • Replacement: Replace severely worn or damaged bearings in a timely manner based on usage and inspection results.

Choosing the right deep groove ball bearing requires considering the following factors:

  • Load Type and Size: Determine the radial and axial loads that need to be supported and select bearings that can meet these load requirements.
  • Operating Speed: Choose the appropriate bearing type based on the operating speed of the equipment, with low-friction designs suitable for high-speed applications.
  • Environmental Conditions: Consider the working environment's temperature, humidity, and contamination levels, and select appropriate sealing designs and materials.
  • Size and Installation: Choose bearings of the right size based on the installation space in the equipment, ensuring ease of installation and maintenance.

Faults in deep groove ball bearings can typically be identified by the following signs:

  • Increased Noise: Abnormal noise during operation may indicate internal wear or damage to the bearing.
  • Enhanced Vibration: Abnormal vibration is often caused by damage to the bearing raceway or rolling elements.
  • Overheating: A significant increase in bearing temperature may be due to poor lubrication or bearing overload.
  • Unstable Operation: A decrease in the stability of equipment operation may be a sign of bearing failure.
