What Are Single Row Deep Groove Ball Bearings?
Single row deep groove ball bearings are one of the most widely used radial ball bearing types. They have deep raceway grooves in both the inner and outer rings, allowing the bearing to support radial loads and limited axial loads in both directions.
Because of their simple structure, low friction, low noise and high-speed capability, they are widely used in electric motors, pumps, fans, conveyors, gearboxes and general industrial machinery.
Structure Components:
- Outer Ring
- Inner Ring
- Steel Balls
- Cage
- Deep Groove Raceway
- Seal / Shield Optional
Engineered for Precision
High-quality components ensure stable rotation and extended service life.
Deep Raceway Geometry
Deep raceway grooves help the bearing carry radial loads and limited axial loads in both directions while maintaining stable rotation.
Steel Balls & Cage
Precision steel balls and a stable cage design help reduce friction, improve running smoothness and support high-speed operation.
Seal / Shield Options
Open, ZZ shielded and 2RS sealed designs are available for different speed, dust, moisture and maintenance requirements.

Common Problems When Buying Deep Groove Ball Bearings
How Haron solves industry pain points for B2B buyers.
Abnormal Noise & Vibration
Inconsistent manufacturing leads to noisy motors and equipment vibration.
100% Noise and vibration testing (Z1/V1 to Z3/V3) before shipment, using premium grease and strict precision control.
Early Bearing Failure
Poor material or incorrect clearance causes premature wear and breakdown.
Strict GCr15 material inspection, advanced heat treatment, superfinishing, and expert guidance on clearance selection (CN/C3).
Unstable Batch Quality
Samples are good, but bulk orders have varying dimensions and performance.
Automated production lines, standardized process control, dimensional inspection, and traceable batch testing.
Confusing Replacement
Difficulty matching existing SKF, NSK, or FAG models with correct specs.
Engineering support for model cross-reference, drawing confirmation, and providing samples for testing before bulk orders.

How to Choose Single Row Deep Groove Ball Bearings
Follow these steps to ensure you select the correct bearing for your equipment.
Confirm Bearing Size
Check bore diameter (d), outer diameter (D) and width (B). If replacing an existing bearing, check the model number on the seal/shield or send us photos.
Check Load and Speed
Confirm radial load, axial load and rotation speed. Higher speed applications may need lower friction seals, suitable clearance and specific lubrication.
Choose Open, ZZ or 2RS
Open is for clean, lubricated systems. ZZ is for dust protection and low friction. 2RS is better for dust/moisture protection but has slightly higher friction.
Select Clearance
CN is standard. C3 is considered for higher temperatures, tighter interference fits, or high-speed electric motor applications.
Confirm Material & Precision
Chrome steel is common. Stainless steel is for wet environments. P0/P6 are standard precision; P5/P4 are for higher accuracy requirements.
Bearing Comparisons
Understanding the differences to make the right choice.
Single Row vs Double Row Deep Groove Ball Bearings
| Item | Single Row | Double Row |
|---|---|---|
| Load Capacity | Standard radial load | Higher radial load capacity |
| Width | Compact, narrower | Wider, requires more axial space |
| Speed | Excellent for high speeds | Slightly lower speed limits |
| When to Choose | General radial load, limited axial space, high speed, economical. | Higher radial load required but axial space is still limited compared to two single bearings. |
Open vs ZZ vs 2RS Deep Groove Ball Bearings
| Type | Friction & Speed | Dust Protection | Moisture Protection | Best For |
|---|---|---|---|---|
| Open | Lowest friction, highest speed | None | None | Clean, oil-lubricated enclosed systems (e.g., gearboxes). |
| ZZ (Shielded) | Low friction, high speed | Good (keeps large particles out) | Poor | Electric motors, fans, general dusty environments. |
| 2RS (Sealed) | Higher friction, lower speed | Excellent | Good | Pumps, agricultural machinery, outdoor equipment. |
