6305-2RS1/LHT55 Bearing Product Overview & Core Advantages
The 6305-2RS1/LHT55 is a 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 and pre-lubrication, which provides robust protection against contaminants and ensures long service life with minimal maintenance. Engineered to primarily handle radial loads, this bearing is characterized by its high running accuracy, consistent performance, and compliance with international standards, making it a dependable choice for general machinery and equipment.
6305-2RS1/LHT55 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Contact seals on both sides | Provides excellent protection against dust, dirt, and moisture ingress, enhancing bearing life in harsh environments. |
| /LHT55 | Filled with LHT55 high-performance grease | Enables reliable operation across the specified temperature range (-30°C to 120°C), offering long-term lubrication and reducing the need for re-lubrication. |
6305-2RS1/LHT55 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring high strength, durability, and resistance to wear.
- Radial Load Capacity: The deep groove raceway and single-row design are optimized to efficiently support significant radial dynamic loads (4631 lbf) and radial static loads (254 lbf).
- Sealed & Pre-Lubricated: The integrated contact seals (2RS1) and LHT55 grease create a "sealed-for-life" system, preventing lubricant leakage and contaminant entry, which is critical for maintenance-free operation.
- Precision & Stability: Built to ABEC 1 | ISO P0 tolerance class with CN radial internal clearance, guaranteeing smooth and precise rotation, low vibration, and consistent performance.
6305-2RS1/LHT55 Bearing Typical Application Areas
This versatile bearing is ideally suited for applications requiring reliable, sealed operation in:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor pulleys)
- Pumps and Fans
- Automotive Components (e.g., alternators, idlers)
