6305-2RS1/LHT23 Bearing Product Overview & Core Advantages
The 6305-2RS1/LHT23 is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. Its primary advantage lies in its sealed design (2RS1) and factory-applied LHT23 high-temperature grease, making it a maintenance-free solution suitable for a wide operating temperature range. This bearing is designed to accommodate primarily radial loads and offers high operational reliability with its precision ABEC 1 (ISO P0) tolerance class, ensuring consistent performance and long service life.
6305-2RS1/LHT23 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6305 | Basic Bearing Series & Size | Denotes a medium-duty deep groove ball bearing with a 25mm bore, 62mm OD, and 17mm width. |
| 2RS1 | Contact Seals on Both Sides | Features nitrile rubber (NBR) seals that provide superior protection against contamination and retain lubricant effectively. |
| LHT23 | High-Temperature Lithium Soap Grease | Specifies a premium grease suitable for a wide temperature range (-30°C to +120°C), offering excellent oxidation stability and long-term lubrication. |
6305-2RS1/LHT23 Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The 2RS1 contact seals provide an effective barrier against dust, moisture, and other contaminants, significantly enhancing bearing life in harsh environments. This design also ensures the LHT23 grease is retained, creating a maintenance-free system.
- Optimized Load Capacity: The single row deep groove raceway geometry is optimized to handle significant radial loads (Dynamic: 4631 lbf / Static: 254 lbf), making it a versatile choice for various applications.
- Precision & Reliability: Manufactured to ABEC 1 (ISO P0) tolerance standards with a standard CN radial internal clearance, this bearing ensures smooth operation, low noise, and consistent performance.
- High-Quality Materials: Constructed entirely from chrome steel for rings, balls, and cage, providing high strength, durability, and resistance to wear.
- High-Speed Capability: With a limiting speed of 11,000 rpm, it is suitable for applications requiring rapid rotation, supported by its optimized internal geometry and effective sealing.
6305-2RS1/LHT23 Bearing Typical Application Areas
The 6305-2RS1/LHT23 is ideally suited for a wide range of industrial and commercial equipment where reliability and minimal maintenance are critical. Common applications include:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems
- Agricultural Machinery
- Material Handling Equipment
- Food Processing Machinery (where the seal and grease are compatible)
