Deep Groove Ball Bearings - Designs and Variants
Single Row Deep Groove Ball Bearings
Single row deep groove ball bearings are the most widely used type, available either capped (with seals or shields) or open. Open bearings that can also be capped may have recesses in the ring side faces.
Stainless Steel Deep Groove Ball Bearings
Stainless steel deep groove ball bearings are corrosion-resistant against moisture and various media. They come in sealed, shielded, or open options. Open bearings that can also be capped might have recesses in the ring side faces. These bearings have a lower load capacity compared to same-sized high chromium steel bearings.
Single Row Deep Groove Ball Bearings with Filling Slots
Single row deep groove ball bearings with filling slots have a filling slot in both the inner and outer rings to accommodate more balls than standard deep groove ball bearings. These bearings have a higher radial load carrying capacity than those without filling slots, but their axial load carrying capacity is limited, and they cannot operate at the same high speeds as bearings without filling slots.
Double Row Deep Groove Ball Bearings
Double Row Deep Groove Ball Bearings are ideal for arrangements where a single row's load capacity is insufficient. With the same bore and outside diameter, double row bearings are slightly wider than single row bearings in the 62 and 63 series but offer significantly higher load capacity. They are available only as open bearings, without seals or shields.

Frequently Asked Questions (FAQs)
Q: What are deep groove ball bearings?
A: Deep-groove ball bearings are the most common type of rolling bearing, designed to handle radial and axial loads. They consist of an inner and outer ring with deep grooves to house the ball elements, ensuring smooth rotation and low friction.
Q: What are the main applications of deep groove ball bearings?
A: Deep groove ball bearings are used in various applications, including electric motors, fans, automotive components, industrial machinery, household appliances, and agricultural equipment. They are versatile and suitable for high-speed and moderate-load scenarios.
Q: What are the benefits of using deep groove ball bearings?
A: Deep groove ball bearings offer low friction, high-speed capability, and the ability to handle radial and axial loads. They are known for their durability, low noise, and ease of maintenance, making them ideal for many applications.
Q: How do I select the right deep groove ball bearing for my application?
A: Consider factors such as the load type (radial or axial), speed, operating temperature, size constraints, and environmental conditions. Choose the appropriate sealing and lubrication options based on your application’s requirements.
Q: What types of seals are available for deep groove ball bearings?
A: Deep groove ball bearings have different sealing options: open, shielded (Z or ZZ), and sealed (RS or 2RS). Shielded bearings protect against large particles, while sealed bearings offer better protection against moisture and fine contaminants.
Q: Can deep groove ball bearings handle axial loads?
A: Yes, deep groove ball bearings can handle moderate axial and radial loads. However, other bearing types like angular contact ball bearings may be more suitable if the application involves predominantly axial loads.
Q: What materials are deep groove ball bearings made of?
A: Deep groove ball bearings are typically made from high-grade steel, such as chrome steel or stainless steel. Ceramic balls or corrosion-resistant materials may be used for specialized applications.
Q: How should deep groove ball bearings be lubricated?
A: Depending on the operating environment and application, deep groove ball bearings can be lubricated with either grease or oil. Pre-lubricated bearings are joint, and maintenance requirements depend on load, speed, and temperature.
Q: What causes deep groove ball bearings to fail?
A: Common causes of failure include insufficient lubrication, contamination from debris or moisture, excessive loads, misalignment, and high temperatures. Proper selection, installation, and regular maintenance can help prevent these issues.
