6309-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6309-2RS1/C3WT is a metric single row deep groove ball bearing engineered for high-performance industrial applications. This sealed bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its key advantages include robust construction using chrome steel for all core components, providing excellent durability and a long service life. The combination of a C3 radial internal clearance and ABEC 1 (ISO P0) tolerance class ensures reliable operation under a wide range of operating conditions, including those with thermal expansion. The integral seals protect against contamination, making it a versatile and reliable choice for various machinery.
6309-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Basic bearing series, indicating a medium duty, single row deep groove ball bearing with a 45mm bore, 100mm OD, and 25mm width. |
| -2RS1 | The bearing is fitted with contact seals on both sides. The RS1 type seals are made of NBR rubber and provide effective protection against the ingress of contaminants and the egress of lubricant. |
| /C3 | Specifies a radial internal clearance greater than normal (C3 group). This is beneficial for applications where thermal expansion is a factor or where interference fits are used, preventing preload and ensuring smooth operation. |
| WT | This suffix indicates the bearing is supplied without lubrication (unlubricated). This allows the end-user to apply a specific lubricant tailored to their application's unique speed, temperature, and environmental requirements. |
6309-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Robust Chrome Steel Construction: Both rings, balls, and the cage are manufactured from high-grade chrome steel, providing high load capacity, wear resistance, and dimensional stability.
- Deep Groove Raceway: The deep, continuous raceways on both rings are optimized to support significant radial loads and moderate axial loads from either direction.
- Enhanced Sealing with 2RS1: The double-contact rubber seals effectively shield the internal components from dust, dirt, and moisture, significantly extending bearing life in harsh environments. They also retain lubricant effectively once applied.
- Optimized Internal Clearance (C3): The C3 clearance provides operational flexibility, accommodating shaft and housing fits and thermal gradients without inducing detrimental preload, which is critical for maintaining bearing performance and preventing premature failure.
- High-Speed Capability: With a limiting speed of 6,700 rpm, this bearing is suitable for a wide range of high-speed applications. The precision-ground components contribute to smooth, low-vibration, and quiet operation.
6309-2RS1/C3WT Bearing Typical Application Areas
The 6309-2RS1/C3WT is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators: For supporting rotor shafts where reliability and speed are paramount.
- Industrial Gearboxes and Transmissions: Handling radial loads in various power transmission systems.
- Material Handling Equipment: Such as conveyor pulleys and rollers.
- Agricultural Machinery: Including pumps and drives that operate in dusty conditions.
- General Industrial Machinery: A reliable choice for pumps, fans, and blowers where sealed, prelubricated units are not specified.
