What Are 2RS Deep Groove Ball Bearings?
2RS deep groove ball bearings are single row deep groove ball bearings equipped with rubber seals on both sides. The seals help retain grease inside the bearing while reducing the entry of dust, dirt and moisture. Compared with open bearings, 2RS bearings are better suited for applications where lubrication maintenance is difficult or where the bearing is exposed to contamination.
They are widely used in electric motors, pumps, conveyor rollers, agricultural machinery, fans, gearboxes and general industrial equipment.
Why Choose 2RS Sealed Deep Groove Ball Bearings?
Better Contamination Protection
When equipment like agricultural machinery operates in open fields, airborne dirt causes wear. Rubber seals on both sides block abrasive particles, protecting the raceway in demanding environments.
Grease Retention
High-speed rotation naturally forces grease outward. 2RS bearings are supplied pre-lubricated with lithium or polyurea grease. The tight seal lips prevent leakage, ensuring stable long-term operation.
Low Maintenance Operation
In enclosed gearboxes or deep-well pumps, manual re-greasing is costly. A sealed design eliminates the need for external grease nipples, reducing downtime for equipment where bearing access is difficult.
Smooth & Low-Noise Rotation
For indoor HVAC fan motors, vibration causes unacceptable noise. Precision ground raceways (P6/P5), quality balls and controlled internal clearance (C3) support smooth running and reduced decibel levels.
Wide Model Availability
Different machine shafts require specific housing dimensions. Haron Bearing supplies standard 6000, 6200, 6300, 6800 and 6900 series 2RS bearings, from d=10mm to large diameters, fitting diverse space constraints.
OEM / ODM Customization
Mass production requires strict consistency. We customize GCr15 steel materials, high-temperature grease, specific seal colors, laser marking, and bulk packaging according to your factory's assembly line requirements.

Open vs ZZ vs 2RS Deep Groove Ball Bearings
Understanding the sealing mechanism is critical for matching bearing speed limits with environmental constraints.
Open Bearing
ZZ Bearing
2RS Bearing
| Feature | Open | ZZ (Metal Shields) | 2RS (Rubber Seals) |
|---|---|---|---|
| Seal Structure | No seal | Metal shields (non-contact) | Rubber seals (contact) |
| Protection | Lowest | Moderate dust protection | Better dust and moisture protection |
| Friction | Lowest | Low | Slightly higher |
| Speed Capability | Highest | High | Medium to high, depending on size and grease |
| Lubrication | External required | Usually pre-greased | Pre-lubricated and grease-retaining |
| Best For | Clean, lubricated systems (e.g. oil bath gearboxes) | Clean equipment, fans, high-speed motors | Dusty, wet or hard-to-service equipment |
Choose 2RS bearings when sealing protection and maintenance reduction are more important than maximum speed. Choose ZZ bearings when the environment is cleaner and lower friction is the priority. Choose open bearings when the application has external lubrication and limited contamination.
