Sealed Deep Groove Ball Bearings Manufacturer
2RS rubber sealed deep groove ball bearings for motors, pumps, gearboxes, conveyors, automation equipment and OEM machinery.
When motor shafts operate in dusty or humid environments, standard open bearings risk early failure. Haron Bearing supplies grease-filled, low-noise and contamination-resistant sealed deep groove ball bearings. We support OEM model confirmation, stable batch precision, and export-ready packaging to reduce your maintenance and assembly issues.
2RS Rubber Sealing
When equipment runs in dirty environments, rubber seals on both sides help retain grease and reduce dust, dirt and moisture ingress, protecting the raceway.
Pre-Lubricated Design
For mechanisms where relubrication is difficult, factory grease filling helps reduce maintenance work and supports stable operation in general industrial applications.
Low-Noise Running
To meet appliance and HVAC standards, these bearings are precision-ground and tested, making them suitable for motors and fans requiring quieter rotation.
OEM Model Support
Available in 6000, 6200, 6300, 6800, 6900 and custom series. We match size, clearance, grease and seal requirements to your specific machinery drawings.

Factory Production for Sealed Deep Groove Ball Bearings
From ring machining and heat treatment to raceway grinding, assembly, grease filling, sealing, noise testing and export packaging. We control the physical supply chain to ensure batch consistency.
What Are Sealed Deep Groove Ball Bearings?
Sealed deep groove ball bearings are single row deep groove ball bearings equipped with rubber seals on one or both sides, commonly marked with suffixes like RS or 2RS. Because open bearings are vulnerable to contamination, the sealing structure helps retain factory-filled lubricant inside the bearing cavity and significantly reduces the entry of dust, moisture and solid contaminants from the working environment.
- Load Capacity: Designed to carry primarily radial loads, while also capable of supporting limited axial loads in both directions.
- Application Environment: More suitable for scenarios with dust, humidity, grease retention needs, or where regular maintenance is difficult to perform.
- Structure Comparison: Compared to ZZ shielded bearings, 2RS rubber seals usually provide better dust and moisture protection, though they may introduce slightly higher friction and torque due to seal contact.

Types of Sealed Deep Groove Ball Bearings We Supply
Whether you are new to bearing selection or an experienced engineer, understanding the right sealing structure is crucial. We offer a variety of configurations to perfectly match your equipment's protection, speed, and environmental needs.
2RS Sealed Bearings
Designed for maximum protection, these bearings feature rubber seals on both sides to keep contaminants out and lubrication in. Perfect for beginners looking for a zero-maintenance, install-and-forget solution.
Excellent Protection
Blocks dust, dirt, and water splashes effectively, ensuring a longer lifespan for your equipment.
Zero Maintenance
Pre-lubricated for life; retains grease securely inside so you never have to re-lubricate.
Common Applications
Widely used in electric motors, water pumps, washing machines, and outdoor garden equipment.
Low-Friction Sealed
If your equipment needs to run fast without getting too hot, low-friction seals (RZ/2RZ) provide the perfect balance. They offer light or non-contact sealing that saves energy while keeping dust away.
Reduced Heat & Friction
Non-contact design means significantly less energy loss and lower operating temperatures.
High-Speed Capable
Allows for much faster rotation speeds compared to standard heavy-contact rubber seals.
Common Applications
Ideal for high-speed electric motors, power tools, precision instruments, and RC vehicles.
Stainless Steel Sealed
Built entirely from high-grade stainless steel, these bearings are your go-to choice for harsh, wet, or hygienic environments where standard steel would quickly rust and fail.
Rust Proof
Outstanding resistance to water, moisture, and chemical corrosion for long-lasting durability.
Food & Medical Grade
Completely safe for hygienic environments, cleanrooms, and frequently washed equipment.
Common Applications
Food processing machinery, medical devices, packaging equipment, and marine applications.
Miniature Sealed
Don't let space constraints limit your design. Our miniature sealed bearings pack full-sized performance and protection into incredibly small dimensions for precise, tiny mechanisms.
Space-Saving Design
Fits perfectly into highly compact spaces with strict dimensional and weight limits.
Micro-Precision
Provides exceptionally smooth rotation for tiny, highly sensitive mechanical movements.
Common Applications
Drones, 3D printers, dental drills, small robotics, and precision office equipment.
Custom Grease Filled
Extreme environments require extreme lubrication. Whether your machine operates in freezing cold or blistering heat, we pre-fill the bearings with the exact grease needed for your specific conditions.
Temperature Resistant
Specially formulated greases tailored for extreme heat or freezing cold environments.
Optimized Fill Volume
Carefully calculated grease volume to prevent overheating or leakage during heavy operation.
Common Applications
Industrial ovens, aerospace components, heavy-duty manufacturing, and extreme weather gear.
Open vs ZZ vs 2RS Deep Groove Ball Bearings
Selecting the right seal structure is critical for balancing rotation speed, friction, and contamination protection in your specific machine design.
Open Bearing
ZZ Shielded
2RS Sealed
| Feature | Open Bearing | ZZ Shielded | 2RS Sealed |
|---|---|---|---|
| Seal Structure | None (Exposed balls) | Metal shields on both sides | Rubber seals on both sides |
| Friction / Torque | Lowest friction | Low friction | Slightly higher (contact seal) |
| Speed Capability | Highest speed | High speed | Moderate to high speed |
| Dust Protection | Poor (Requires external seal) | Good for dry dust | Excellent protection |
| Moisture Protection | Poor | Fair | Better resistance to moisture |
| Grease Retention | Requires oil bath/external lube | Good | Excellent retention |
| Typical Applications | Clean, high-speed gearboxes | Clean motors, light industry | Dirty, humid, outdoor machinery |
Recommendation
Choose 2RS sealed deep groove ball bearings when contamination protection, grease retention and reduced maintenance are more important than the absolute lowest friction.

Common Problems When Sourcing Sealed Ball Bearings
Incorrect bearing selection often leads to assembly issues or premature failure. Here is how Haron Bearing engineers solve typical procurement challenges.
Early Failure from Contamination
Bearing fails early because dust or moisture enters the raceway due to improper seal selection.
Solution:Recommend correct seal type (2RS/2RZ), grease and clearance according to specific environment.
Overheating Issues
Bearing runs hot because seal friction, high speed and standard grease are not properly matched.
Solution:Help choose low-friction seal, high-speed grease and appropriate clearance for operating speed.
High Motor Noise
Motor noise is too high after assembly, causing QC rejection of the final equipment.
Solution:Provide low-noise bearing options, conduct strict noise/vibration testing and batch inspection.
Lack of Customization
Supplier only sells standard off-the-shelf models and cannot support OEM application modifications.
Solution:Support model confirmation, custom grease, clearance, precision, seal material and packaging.
