603 2rs Bearing Product Overview & Core Advantages
The 603 2RS is a single row deep groove ball bearing designed for reliable performance in compact spaces. Featuring integral rubber seals (2RS) on both sides, it offers superior protection against contaminant ingress while retaining lubrication. This metric bearing is engineered to handle primarily radial loads and is characterized by its low friction operation, making it a cost-effective and versatile solution for a wide range of industrial applications requiring consistent performance and extended service life.
603 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 603 | Standard bearing series designation, indicating a metric deep groove ball bearing with a 3mm bore, 9mm OD, and 5mm width. |
| 2RS | Contact Rubber Seals on both sides. This provides excellent protection against dust and moisture, making the bearing pre-lubricated and shielded for long-term operation. |
603 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The Nitrile Rubber (NBR) seals (2RS) effectively shield the internal components from contaminants and retain the factory-applied grease, significantly enhancing bearing life in demanding environments.
- Precision & Reliability: Manufactured to ABEC1 tolerance class with a C3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and reliable operation under standard operating conditions.
- High-Quality Materials: Constructed from Chrome Steel rings and balls with a Stainless Steel cage, offering good durability and corrosion resistance.
- Optimized for Radial Loads: The deep groove raceway and six precision balls are designed to efficiently carry the specified radial dynamic load rating of 52 lbf and radial static load rating of 34 lbf.
- Compact & Lightweight: With dimensions of 3x9x5 mm and a weight of only 0.84 g, it is ideal for applications with severe space and weight constraints.
