6308-2RS1/HC5C3GJN Bearing Product Overview & Core Advantages
The 6308-2RS1/HC5C3GJN is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This sealed bearing features a hybrid ceramic design with Silicon Nitride (Si3N4) balls, offering superior operational characteristics. Its primary advantages include the ability to handle significant radial loads, extended service life due to reduced wear, and reliable operation across a wide temperature range. The combination of a C3 radial internal clearance and high-quality construction makes it a robust and durable choice for various industrial settings.
Model Code In-Depth Explanation
- 6308: Basic model number denoting a single row deep groove ball bearing with a 40mm bore, 90mm OD, and 23mm width.
- 2RS1: Designates that the bearing is equipped with contact seals on both sides, providing effective protection against contaminants and retaining lubricant.
- HC5: Indicates the use of Hybrid Ceramic components, specifically Silicon Nitride (Si3N4) balls.
- C3: Specifies a greater than normal radial internal clearance, suitable for applications with thermal expansion or where interference fits are used.
- GJN: A manufacturer-specific code, often related to internal specifications or special greasing processes (Note: Lubrication is specified as "None" in the provided data).
6308-2RS1/HC5C3GJN Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The use of Silicon Nitride balls with chrome steel rings results in lower friction, higher limiting speed (7,500 rpm), and significantly longer service life compared to all-steel bearings. This construction also provides enhanced resistance to electrical erosion.
Robust Load Capacity: With a dynamic load rating of 915 lbf and a static load rating of 5395 lbf, this bearing is designed to handle substantial radial loads reliably.
Effective Sealing & Environmental Protection: The 2RS1 double-contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, ensuring consistent performance in challenging environments.
Precision & Stability: Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures smooth and precise operation, while the C3 clearance accommodates thermal expansion in applications, preventing premature failure.
6308-2RS1/HC5C3GJN Bearing Typical Application Areas
This bearing is ideally suited for applications requiring high speed, long life, and reliable operation under radial loads. Common uses include:
- Electric Motors & Generators (especially where electrical insulation or higher speeds are beneficial)
- Pumps & Compressors
- Material Handling Equipment
- Agricultural Machinery
- Industrial Fans & Blowers
