Deep Groove Ball Bearings

As one of the most popular types of bearings, deep groove ball bearings (also called Conrad bearings) are known for their ability to support both axial and radial loads at the same time. Their durable, low-friction design makes them more than suitable for high-speed applications across many industries. Our premium deep groove ball bearings serve as ideal replacements for well-known brands including SKF, Timken, NTN, NSK, McMaster-Carr and FAG.

What are Deep Groove Ball Bearings?

The main components in Conrad bearings include the:

• Inner ring
• Outer ring
• Ball set
• Cage to hold the components in place

As the name suggests, deep groove ball bearings are designed with raceways (i.e., grooves) that allow them to support radial and axial loads from different angles. They’re crafted from materials like stainless steel that offer excellent corrosion resistance and a long service life in a range of conditions. 

Types of Deep Groove Ball Bearings

Conrad bearings come in different designs and materials. Some of the most common designs include shielded, sealed, open, and closed options. Each design is manufactured to meet the needs of various industrial and commercial applications. 

Single Row Deep Groove Ball Bearings

These bearings can be spotted in electric motors, car transmissions, gearboxes, household appliances and more. They’re incredibly versatile and can handle both radial and axial loads across many applications.

Stainless Steel Deep Groove Ball Bearings

From food processing equipment and marine applications to medical equipment, deep groove ball bearings made of stainless steel are great for situations requiring corrosion resistance and durability in moist or harsh conditions. 

Flanged Ball Bearings

The flange and outer ring help to prevent axial movement while making it much easier to position. They can be found in conveyor systems, robotics, farming equipment, and many other applications that call for simple mounting and precise positioning. 

Single Row Deep Groove Ball Bearings With Filling Slots

The additional slots on these bearings help to support more balls, which increases the load-carrying capacity. Single row deep groove ball bearings are excellent for heavy-duty machinery that requires the ability to support higher radial loads.

Snap Ring Groove Ball Bearings

Electric motors, pulley and gear systems, and common car parts all require ball bearings with snap-ring grooves. They’re easy to install in tight spaces and allow for smooth rotations. The groove helps ensure the bearing stays in place without the need for more parts. 

Double Row Deep Groove Ball Bearings

Typically reserved for applications that require a higher load-carrying capacity than what single-row bearings can offer. The double-row design allows for even load distribution, making them ideal for industrial equipment, electric car parts, and many other environments.

How They Work

The deep raceways, precise design and spherical rolling elements help deep groove ball bearings reduce friction and enable high-speed rotation. Unlike angular contact ball bearings (which specialize in combined loads), deep groove ball bearings are incredibly versatile. This makes them more than suitable for light and heavy applications. 

Common Applications for Deep Groove Ball Bearings

Due to their versatility, high performance and affordability, it would be very challenging to find an industry where deep groove ball bearings are not used. 

Automotive Industry

Mostly used to handle radial and axial loads in engines, gearboxes and transmissions. 

Electric Motors

Excellent for high-speed electric motors and other applications that call for low friction and high-performance parts. 

Industrial Machinery

Provides efficiency gains for many types of machinery by supporting radial loads and reducing friction. 

Consumer Electronics

Can be found in common computer and electronic parts (i.e., fans, drives, etc.) where quiet and efficient operation is essential. 

Aerospace Sector

Aircraft systems require these bearings because they can withstand a high-load capacity, are low friction, and offer reliable performance under extreme conditions. 

Benefits & Advantages

These bearings have been a game changer ever since Sven Wingquist, the founder of SKF, developed deep groove ball bearings in the early 20th century. 

They’ve become so popular due to their: 

• Ability to handle heavy radial and axial loads efficiently
• Corrosion resistance and overall durability 
• Low friction, which reduces wear and improves performance
• Highly versatile designs that allow use in many applications
• Ability to maintain contaminant-free in a sterile environment 

How to Choose the Right Deep Groove Ball Bearing

If you want to choose the right Conrad bearing, you’ll first need to ask yourself a few questions, including: 

• Does my bearing need to support higher radial and/or axial loads?
• Is this a high-speed application that requires low friction and stable performance? 
• Will the bearing be exposed to contaminants, moisture, or harsh operating temperatures? 
• What special features do I need (i.e., sealed, shielded, strong cage material, etc.)?
• What are the lubrication needs? 

Your answers to these questions can help to point you in the direction of the ideal deep groove ball bearing, but you don’t have to search alone. Contact us to speak with our knowledgeable customer service team about your project needs, and we’ll help you find the perfect deep groove ball bearing for your next project. 

Maintenance & Lubrication Tips

The better you take care of your deep groove ball bearings, the longer they’ll last and the less they’ll cost you in the long run. Here are a few tips to help maximize the lifespan of your ball bearings:

• Apply Lubrication Regularly: Material-appropriate lubricants can keep the bearings running longer and more smoothly.
• Inspect for Contaminants: Contaminated bearing units can drastically reduce performance. 
• Keep an Eye on The Operating Temperature: Extremely high temperatures can lead to overheated bearings, which can result in expensive repairs. 
• Proper Alignment: Misaligned Conrad bearings lead to faster than normal wear and tear. 
• Listen for Noise & Vibration: Inspect the bearings and listen for any unusual noises or vibrations that could be of concern.
