What Are Deep Groove Ball Bearings?
Deep groove ball bearings are the most widely used rolling bearings due to their simple design, high efficiency, and exceptional versatility. These bearings are engineered to reduce friction while supporting both radial and axial loads in both directions, making them suitable for a wide range of industrial and commercial applications.
Thanks to their deep raceway grooves and close conformity between the balls and raceways, deep groove ball bearings offer high rotational speeds, low vibration, and quiet operation. Their robust construction, ease of installation, and minimal maintenance requirements make them one of the most cost‑effective bearing solutions available today.
At Alma Bearings, our deep groove ball bearings catalogue includes a full range of sizes, configurations, and precision classes designed to meet both standard and demanding operating conditions.
Types of Deep Groove Ball Bearings
Single Row Deep Groove Ball Bearings
Single row designs are the most common type and are ideal for high‑speed and low‑noise applications. They provide an excellent balance between performance, durability, and affordability, making them widely used in electric motors, pumps, and household appliances.
Double Row Deep Groove Ball Bearings
Double row deep groove ball bearings feature increased load‑carrying capacity while maintaining compact dimensions. These bearings are well suited for heavy‑duty applications such as conveyor systems, compressors, and industrial gearboxes.
Four Point Contact Ball Bearings
Four point contact bearings are designed to accommodate high axial loads in both directions. Their unique internal geometry allows axial load support using fewer components, making them suitable for aerospace systems, precision machinery, and specialized mechanical assemblies.
Deep Groove Precision Bearings
Deep groove precision bearings are manufactured with tighter tolerances and higher accuracy classes to deliver superior performance in demanding environments. These bearings are commonly used in CNC machines, robotics, medical devices, and high‑speed automation equipment where accuracy, smooth rotation, and consistent performance are critical.
Available in multiple precision grades, deep groove precision bearings help improve positioning accuracy, reduce energy loss, and extend equipment service life.
Technical Specifications & Bearing Variants
Deep groove ball bearings are available in a wide range of technical configurations to suit different operating requirements.
Common specifications include:
- Bore size range: 3 mm to 200+ mm
- Load capability: Radial loads with moderate axial loads
- Speed performance: Suitable for high‑speed operation
- Internal clearance classes: CN, C3, C4
- Cage materials: Steel, brass, or polymer
- Design standards: Metric and imperial sizes
Sealed and Shielded Options
- Open bearings – Suitable for clean, controlled environments
- Shielded (ZZ) – Protection against dust and debris with high speed capability
- Sealed (2RS / 2RS1) – Rubber seals for moisture and contamination resistance
Choosing the correct seal or shield type directly affects bearing performance, lifetime, and maintenance intervals.
Deep Groove Ball Bearings Chart
A deep groove ball bearings chart is an essential tool for selecting the correct bearing size and specification. Bearing charts typically include:
- Inside diameter (ID)
- Outside diameter (OD)
- Width
- Dynamic and static load ratings
- Speed limits
Using a bearing chart ensures accurate replacement, proper fit, and optimal operational performance for your application.

Frequently Asked Questions
How do I measure a deep groove ball bearing?
Measure the inside diameter (ID), outside diameter (OD), and width using a caliper or micrometer. These three dimensions are essential for identifying the correct bearing size.
What is the difference between sealed and shielded deep groove ball bearings?
Shielded bearings (ZZ) protect against dust while maintaining high speed capability. Sealed bearings (2RS) provide better protection against moisture and contaminants but may have slightly lower speed limits.
Are deep groove ball bearings suitable for axial loads?
Yes, deep groove ball bearings can support axial loads in both directions in addition to radial loads, making them highly versatile for many applications.
