6308-2RS1/C3GLE9 Bearing Product Overview & Core Advantages
The 6308-2RS1/C3GLE9 is a sealed single row deep groove ball bearing designed for demanding industrial applications. Engineered to primarily handle radial loads, its robust construction ensures reliable performance and long service life. A key feature is its C3 radial internal clearance, which makes it suitable for applications with thermal expansion or where interference fits are used. The integrated seals provide effective protection against contamination, making this bearing a durable and maintenance-friendly solution for a wide range of machinery.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6308 | Standard series designation for a medium-duty, single row deep groove ball bearing with a 40mm bore. |
| -2RS1 | Indicates the bearing is fitted with two rubber contact seals (RS1 type) on both sides, offering superior protection against contaminants and moisture retention. |
| /C3 | Specifies a greater than normal radial internal clearance. This is crucial for applications involving high operational temperatures or heavy interference fits to prevent excessive preload and overheating. |
| GLE9 | Likely refers to a specific high-performance grease filling, optimized for the stated temperature range and operating conditions. |
6308-2RS1/C3GLE9 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers excellent strength and durability. With a radial dynamic load rating of 915 lbf and a static load rating of 5395 lbf, it is well-suited for applications with significant radial forces.
- Effective Sealing for Contaminated Environments: The 2RS1 rubber contact seals are highly effective at excluding dirt, dust, and moisture while retaining lubricant. This significantly extends bearing life and reduces maintenance needs in harsh conditions.
- Optimized Internal Clearance: The C3 clearance provides operational stability in applications prone to thermal expansion, preventing binding and ensuring smooth rotation under varying thermal conditions.
- Standard Precision & High-Speed Capability: Conforming to ABEC 1 | ISO P0 tolerance class, it provides reliable performance for most industrial applications. The limiting speed of 7,500 rpm makes it a competent choice for a variety of high-speed drives and machinery.
6308-2RS1/C3GLE9 Bearing Typical Application Areas
The 6308-2RS1/C3GLE9 is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
