The 602 2RS bearing is a widely used member of the Ball Bearings family, specifically categorized under Miniature Bearings and further defined as a Metric Size Standard Miniature Ball Bearing. With its compact dimensions, rubber-sealed design, and stable performance, the 602 2RS is engineered for equipment that requires both small size and dependable rotational accuracy.
This model is especially popular among manufacturers who need smooth operation in limited spaces—common in small motors, home appliances, medical devices, measuring instruments, and micro-mechanical assemblies.
What Defines the 602 2RS Bearing?
As a metric-size miniature ball bearing, the 602 2RS maintains standardized dimensions that simplify replacement, design integration, and global sourcing. The “2RS” suffix indicates double rubber seals, which provide excellent protection against dust, moisture, and light contaminants.
These characteristics ensure stable performance even in environments where lubricant integrity is crucial.
Key Features of the 602 2RS
-
Double rubber seals for improved dust and moisture protection
-
Low friction and low noise suitable for high-speed rotation
-
Compact metric-dimension structure ideal for miniature equipment
-
Durable carbon steel or stainless-steel options depending on application requirements
-

Technical Specifications of 602 2RS
| Parameter | Value (Typical) | Description |
|---|---|---|
| Inner Diameter (d) | 2 mm | Fits miniature shafts |
| Outer Diameter (D) | 7 mm | Compact OD for limited-space designs |
| Width (B) | 3 mm | Slim profile for micro-mechanisms |
| Sealing Type | 2RS | Dual rubber seals |
| Category | Metric Size Standard Miniature Ball Bearings | Ensures dimensional standardization |
These standardized metric dimensions place the 602 2RS firmly within the Miniature Bearings subset of the broader Ball Bearings classification.

Performance Benefits for Miniature Applications
Because of its small size and sealing configuration, the 602 2RS is favored for precision miniature systems. Its construction reduces noise and vibration, offering stable performance even in continuous operation.
Applications where the 602 2RS is commonly used:
-
Micro DC motors and stepper motors
-
Office automation devices
-
Compact household appliances
-
Precision medical and laboratory instruments
-
Hobby equipment, RC models, and micro gearboxes
In many of these devices, the reliability of a sealed miniature ball bearing directly affects service life and operational consistency. The 602 2RS delivers the balance of durability and efficiency that these industries demand.
Why Choose a 602 2RS Over Open or Shielded Miniature Bearings?
Compared with open or metal-shielded miniature ball bearings, the 602 2RS provides superior sealing efficiency. This makes it particularly suitable for environments with light particulate exposure or where long lubrication retention is desired.
Advantages at a glance:
-
Better contamination resistance than metal shields (ZZ type)
-
Extended grease life due to sealing protection
-
Ideal for both high-speed and intermittent start-stop operations
For designers choosing between options within the Miniature Bearings category, the 2RS configuration is typically preferred for durability and reduced maintenance.
Conclusion: A Compact, Reliable Choice for Precision Equipment
The 602 2RS bearing stand s out as an essential component within Metric Size Standard Miniature Ball Bearings, offering a combination of compact size, long service life, and effective sealing. Its alignment with the broader Ball Bearings category ensures consistent performance, standardization, and compatibility across multiple industries.
Whether you are designing a new product or sourcing replacements, the 602 2RS is a dependable miniature bearing solution that meets technical, performance, and durability requirements.
