6306-2RS1/LT20 Bearing Product Overview & Core Advantages
The 6306-2RS1 is a single row deep groove ball bearing designed for exceptional reliability in a wide range of industrial applications. As a metric bearing with a sealed construction, its core advantage lies in its ability to handle significant radial loads while offering protection from contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent performance and high operational reliability, making it an ideal, cost-effective solution for general machinery requiring robust and durable sealed bearing performance.
6306-2RS1/LT20 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -2RS1 | Contact rubber seals on both sides | Provides effective protection against the ingress of contaminants like dust and moisture, and retains lubricant. This is crucial for applications in harsh environments. |
| /LT20 | Pre-lubricated with a specific high-quality lithium-based grease | Ensures immediate and smooth operation from startup. The grease is suitable for the specified temperature range of -30°C to 120°C, contributing to the bearing's long service life and reduced maintenance needs. |
6306-2RS1/LT20 Bearing Structural Features & Performance Benefits
- Robust Construction for High Load Capacity: The single row deep groove raceway and high-quality chrome steel components (rings, balls, cage) provide a high radial dynamic load rating of 6002 lbf and a radial static load rating of 3372 lbf, ensuring durability under demanding conditions.
- Effective Sealing for Contamination Resistance: The integral contact seals (2RS1) significantly enhance the bearing's lifespan by shielding the internal components from abrasive particles and moisture, making it suitable for dirty or wet operational environments.
- Optimized for Reliable Operation: With a standard CN radial internal clearance and ABEC 1 precision, this bearing offers a balanced combination of running accuracy, smooth operation, and thermal expansion accommodation. The limiting speed of 9,600 rpm is well-suited for a broad spectrum of industrial machinery.
- Ready-to-Install and Low Maintenance: The factory-applied LT20 grease lubrication means the bearing is prepped for immediate use, reducing installation time and the need for initial lubrication, thereby supporting a maintenance-free design philosophy.
6306-2RS1/LT20 Bearing Typical Application Areas
The 6306-2RS1/LT20 is a versatile component found in numerous sectors due to its balanced performance and sealed design. Key applications include:
- Electric Motors and Gearboxes: For supporting shafts and managing radial loads in standard industrial motors.
- Material Handling Equipment: Conveyor rollers, pulleys, and other machinery requiring reliable, sealed bearings.
- Agricultural Machinery: Implements and equipment exposed to dust, dirt, and varying weather conditions.
- Industrial Fans and Blowers: Where continuous operation and protection from airborne contaminants are essential.
- General Industrial Machinery: Pumps, compressors, and other equipment where a robust, pre-lubricated, and sealed ball bearing is specified.
