602x 2rs Bearing Product Overview & Core Advantages
The 602x 2rs is a metric single row deep groove ball bearing designed for high reliability in compact applications. Its key advantage lies in its integrated Nitrile rubber contact seals (2RS) on both sides, which provide superior protection against contamination while retaining lubricant. This sealed bearing is engineered to handle primarily radial loads and is pre-lubricated for immediate use, offering a long service life with minimal maintenance. Its small footprint, with a 2.5 mm bore and 8 mm outside diameter, makes it an ideal precision bearing for applications demanding space-saving solutions and consistent performance.
602x 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 602x | Bearing series and size code | Indicates a miniature deep groove ball bearing with a 2.5 mm bore and 8 mm outside diameter. |
| 2RS | Double-sided Nitrile Rubber Contact Seals | Provides effective protection from dust and moisture ingress and retains lubricant, enhancing bearing life in contaminated environments. |
602x 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The double-sided Nitrile rubber contact seals (2RS) make the bearing highly resistant to contaminants, making it suitable for demanding environments. This design also effectively retains the pre-applied lubricant, contributing to its low-maintenance characteristic.
- High-Grade Materials: Constructed from Chrome Steel rings and balls with a Stainless Steel cage, this bearing offers excellent durability and corrosion resistance, ensuring stable performance.
- Precision & Load Capacity: Manufactured to ABEC1 tolerance standards, it provides reliable running accuracy. With a radial dynamic load rating of 106 lbf, it is capable of handling significant radial loads for its size.
- Optimized Internal Geometry: The deep groove raceway and MC3 radial internal clearance (0.002mm to 0.013mm) are designed for smooth operation and to accommodate slight misalignments or thermal expansion.
602x 2rs Bearing Typical Application Areas
Due to its compact bearing dimensions, sealed design, and reliable performance, the 602x 2rs is widely used in:
- Small electric motors and precision instruments
- Office automation equipment (printers, scanners)
- Medical devices and dental handpieces
- Radio control models (drones, RC cars)
- Computer cooling fans and small gearboxes
