63805 2rs Bearing Product Overview & Core Advantages
The 63805 2RS is a metric single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Its core advantage lies in its sealed design (2RS), which provides robust protection against contaminants and retains lubricant, ensuring long service life with minimal maintenance. Engineered to primarily handle radial loads, this bearing is characterized by its compact cross-section, high running accuracy (ABEC-1 tolerance), and consistent operation within a broad temperature range. It is an ideal, cost-effective solution for applications demanding reliability and durability.
63805 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63805 | Basic bearing designation, indicating a single row deep groove ball bearing with a 25 mm bore and 37 mm outside diameter. |
| 2RS | Signifies contact seals on both sides of the bearing. The "RS" denotes a Nitrile Rubber (NBR) seal, offering excellent protection against dust, moisture, and other contaminants, while effectively retaining lubricant. |
63805 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing for Enhanced Durability: The dual 2RS contact seals are a key structural feature, providing a high degree of protection. This makes the bearing suitable for dirty or humid environments, significantly extending its operational life by preventing contamination and lubricant loss.
- Optimized for Radial Loads: The single row deep groove construction is efficiently designed to carry substantial radial loads, as evidenced by its dynamic load rating of 968 lbf.
- Precision and Consistency: Manufactured to ABEC-1 precision class standards, this bearing ensures smooth and quiet operation, reducing vibration and noise in sensitive applications.
- Stable Internal Clearance: The C0 radial internal clearance group (0.006mm to 0.020mm) is standard for general applications, providing stable performance under normal operating conditions and temperatures.
- High-Quality Material Construction: The combination of chrome steel rings and balls with a stainless steel cage offers excellent resistance to wear and corrosion, contributing to the bearing's overall reliability and long service life.
