6309-2RS1/LT20 Bearing Product Overview & Core Advantages
The 6309-2RS1/LT20 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This metric bearing excels at handling high radial loads and moderate axial loads in both directions. Its sealed construction with pre-lubrication ensures long-term reliability and maintenance-free operation, making it an ideal choice for applications requiring high reliability and simplified installation. The bearing is manufactured to ABEC 1 | ISO P0 tolerance standards, providing consistent and predictable performance.
6309-2RS1/LT20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Basic bearing designation indicating a single row deep groove ball bearing with a 45 mm bore, 100 mm OD, and 25 mm width. |
| 2RS1 | Features contact seals on both sides, providing superior protection against contaminants and effective grease retention. |
| LT20 | Indicates the bearing is pre-lubricated with a specific high-quality grease, optimized for the specified operating temperature range. |
6309-2RS1/LT20 Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength, durability, and resistance to wear.
High Load Capacity: The optimized deep groove raceway and robust design enable it to support significant radial dynamic loads (11,915 lbf) and static loads (7,194 lbf).
Sealed & Pre-Lubricated Design: The 2RS1 contact seals effectively shield the internal components from dust, moisture, and other contaminants while retaining the LT20 grease. This combination ensures a long service life and eliminates the need for relubrication in many applications.
Precision & Consistency: Built to ABEC 1 (ISO P0) tolerance class with a standard CN radial internal clearance, it guarantees smooth, low-vibration operation and reliable performance.
