2RS sealed deep groove ball bearings use contact rubber seals on both sides of a single row raceway groove race—factory pre-lubricated and ready for dusty motor, pump, and conveyor shafts where shielded types (ZZ) cannot block fine grit or splash water.
Who is this for? OEM buyers and maintenance teams sourcing metric radial ball bearings with better seal contact than metal shields in 6000 / 6200 / 6300 series.
What matters first? Lock inner diameter, outer diameter, and thickness to housing fits, then confirm radial load and light axial load headroom for your RPM tier.

| 6200-2RS | 10 mm | 30 mm | 9 mm |
| 6300-2RS | 10 mm | 35 mm | 11 mm |
| 6204-2RS | 20 mm | 47 mm | 14 mm |
Premium Material Options
We select materials based on your specific environmental demands:
- Chrome Steel: Our standard for high-performance. A chrome steel ball bearing offers maximum durability and excellent wear resistance for everyday industrial use.
- Stainless Steel: Best for wet environments or food-grade applications where rust prevention is mandatory.
- Ceramic: Ideal for specialized, ultra-high-speed projects requiring low thermal expansion and minimal weight.
Load Ratings and Speed Limits
Our radial deep groove ball bearings 2RS design features deep raceway grooves to handle two types of stress:
- Radial Load: The primary weight pressing down on the shaft.
- Axial Load: Moderate side-to-side force.
Because these are rubber sealed ball bearings, the rubber seals create slight contact with the inner ring. While this design provides the ultimate bearing dust shield protection, it slightly lowers the maximum RPM compared to open or shielded types. If your project involves a high speed electric motor bearings application, we typically configure these with a C3 clearance bearings setup to handle the heat and expansion without seizing. Every unit comes pre-lubricated with premium grease to maximize its operating lifespan right out of the box.
With ID/OD/W locked, the seal geometry below explains how 2RS contact lips retain grease and block contaminants versus ZZ and open types.
What Are 2RS Sealed Deep Groove Ball Bearings?
2RS sealed deep groove ball bearings are the most versatile and widely used bearing type on the market today.
These components feature a single row of rolling elements inside deeply machined raceway grooves on the inner and outer rings—managing radial load and light axial load on one deep groove ball bearing race. For custom seal programs, compare OEM sealed deep groove ball bearings.
Definition of 2RS Double Rubber Seals
The “2RS” designation indicates that the bearing features double rubber seals—one securely fitted on each side. These seals are typically made from nitrile butadiene rubber (NBR) and reinforced with a steel insert.
Unlike basic metal shields, our rubber sealed ball bearings physically contact the inner ring. This contact design forms a tight, secure barrier that locks in the pre-lubricated grease while completely blocking external contamination.
Key Differences: 2RS vs. ZZ vs. Open Bearings
Selecting the correct configuration drastically impacts the life expectancy and durability of your machinery. While a chrome steel ball bearing offers excellent core strength, its enclosure type dictates where it can be used.
| Bearing Type | Enclosure Style | Contamination Protection | Speed Capability | Best Environment |
|---|---|---|---|---|
| 2RS | Contact Rubber Seals | Excellent (Blocks dust & moisture) | Moderate (Standard high speed) | Dusty, dirty, or damp areas |
| ZZ | Non-Contact Metal Shields | Fair (Blocks large debris only) | High | Clean, dry environments |
| Open | None | None (Requires external oil bath) | Maximum | Sealed gearboxes |
- 2RS (Rubber Sealed): Best for maximum protection. The contact seal keeps dirt out and grease in, making it a true pre-lubricated ball bearing requiring zero maintenance.
- ZZ (Shielded Types): Uses non-contact metal plates. They offer less friction for ultra-high speeds but cannot stop fine dust or liquid moisture.
- Open Bearings: Have no built-in protection. They rely entirely on clean, external lubrication systems.
Seal contact trades a few RPM points for field durability—the performance comparison in the next section quantifies that trade-off.

Selecting 2RS Bearings — Clearance, Load & Environment
Choosing the right 2rs sealed deep groove ball bearings comes down to matching the bearing specs to your operating conditions. Lock in the exact fit based on three critical factors: internal clearance, load capacities, and environment.
C3 Clearance vs. Standard Clearance
Internal clearance is the total room between the bearing rings and the rolling elements. Getting this wrong leads to premature failure.
- Standard Clearance: Best for normal operating temperatures and standard electric motors where shaft expansion is minimal.
- C3 Clearance Bearings: Features extra room to handle thermal expansion. We highly recommend C3 clearance for high-speed or high-heat applications where the shaft is bound to heat up and expand.
Matching Load Requirements
Radial ball bearings are designed primarily for radial load (forces perpendicular to the shaft). While they can handle some axial load (thrust forces parallel to the shaft), overloading them kills durability.
| Load Type | Application Match | Best Practice |
|---|---|---|
| High Radial / Low Axial | Conveyors, Electric Motors, Alternators | Standard double sealed deep groove bearing works perfectly. |
| Moderate Combined Loads | Power Tools, Light Agricultural Equipment | Ensure proper shaft alignment to minimize friction. |
| High Axial / Thrust | Heavy Pumps, High-Angle Drives | Pair with a dedicated thrust bearing instead. |
Temperature Limits and Environmental Factors
The rubber seals on a pre-lubricated ball bearing provide excellent protection, but they have physical limits.
- Standard Temperature Range: -20°C to +120°C (-4°F to +248°F). The standard nitrile rubber (NBR) seals and factory grease hold up perfectly in this window.
- Chemical & Moisture Exposure: For outdoor power equipment or washdown environments, our chrome steel ball bearing lineup with reinforced synthetic rubber keeps contaminants completely locked out.
Once clearance and load envelopes are confirmed, map the same 2RS platform to the duty cycles below.

Correct press-fit and seal handling on install preserves the pre-lubricated service life these applications expect.
2RS Sealed Deep Groove Ball Bearings Installation & Maintenance
Getting the most out of your 2rs sealed deep groove ball bearings comes down to correct installation and knowing when to leave them alone. Because these are pre-lubricated ball bearing units, improper handling can ruin the seals before the machine even runs.
Proper Tools for Press-Fitting Bearings
Never strike the outer ring if you are mounting the bearing onto a shaft, and never hit the inner ring if you are pressing it into a housing. Doing so causes “brinelling”—microscopic dents in the raceway grooves that lead to premature failure.
- Use a press or sleeve: Apply force only to the ring experiencing the tight fit.
- Align perfectly: Ensure the radial ball bearings enter straight to avoid scoring the shaft.
- Avoid the rubber seals: Keep all tools clear of the delicate rubber lips to prevent grease leaks.
Signs of Bearing Wear and Failure
Monitor machinery for these early warning signs:
| Symptom | Likely Cause | Action Required |
|---|---|---|
| Excessive Noise / Grinding | Contamination or lack of grease | Replace immediately |
| Increased Vibration | Damaged chrome steel balls or raceways | Replace immediately |
| High Operating Heat | Overloading or seal friction | Inspect alignment and load |
When to Replace vs. Clean a Sealed Bearing
The rule for a double sealed deep groove bearing is simple: Replace, do not clean.
- Do not wash them: Prying off the rubber seals to wash out old grease damages the seal lip permanently.
- Zero maintenance design: These rubber sealed ball bearings are engineered to be maintenance-free for life. Once the grease degrades or dirt gets inside, the bearing has reached the end of its service cycle.
- Cost-efficiency: Swapping in a fresh, factory-sealed unit is always cheaper and more reliable than trying to service a compromised seal.
FAQs About 2RS Sealed Deep Groove Ball Bearings
Quick answers to the most common questions about 2rs sealed deep groove ball bearings.
What does 2RS stand for on a bearing?
The 2RS designation literally means Two Rubber Seals. It signifies that the double sealed deep groove bearing has a synthetic rubber seal on both sides of the inner and outer rings. These rubber sealed ball bearings keep vital lubrication inside while keeping contaminants out.
Can you remove the rubber seals to re-grease a 2RS bearing?
Yes, you can carefully pop the seals off with a small pick, but we do not recommend it. As a manufacturer, we supply every pre-lubricated ball bearing with the exact grease volume required for its entire lifespan. Removing the seal risks tearing the lip or introducing dirt, which ultimately shortens the bearing’s life.
Is a 2RS bearing waterproof?
No radial ball bearings 2RS setup is completely waterproof under high pressure or submersion. However, they are highly water-resistant. The rubber seals offer excellent protection against splashing water, heavy moisture, and everyday washdowns compared to open or shielded types.
What is the difference between 2RS and 2RSH?
While both feature rubber seals, they handle sealing differently depending on the brand design, such as SKF.
| Feature | 2RS Bearings | 2RSH Bearings |
|---|---|---|
| Seal Type | Standard dual-lip rubber seal | Heavy-duty, optimized contact seal |
| Friction Level | Low friction, runs cooler | Slightly higher friction due to tighter seal |
| Dust/Water Protection | Excellent for standard industrial use | Superior protection in harsh, dusty, or wet environments |
