6004-2RSL/C3 Bearing Product Overview & Core Advantages
The 6004-2RSL/C3 is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. This metric bearing features integrated contact seals for effective contamination protection and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and smooth operation. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and robust solution for a wide range of industrial machinery. The pre-defined C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used.
6004-2RSL/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6004: Basic model number denoting a single row deep groove ball bearing with a 20mm bore, 42mm OD, and 12mm width.
- 2RSL: Designates double lip seals on both sides. The "RSL" suffix indicates low-friction synthetic rubber seals with steel reinforcements, offering superior sealing effectiveness compared to standard shields or seals.
- C3: Indicates a greater radial internal clearance than the standard CN group. This is essential for applications involving elevated operational temperatures, shaft misalignment, or heavy interference fits, preventing premature bearing failure due to excessive preload.
6004-2RSL/C3 Bearing Structural Features & Performance Benefits
Robust Sealing for Long Service Life: The double lip seals (2RSL) provide excellent protection against contaminants like dust and moisture, while effectively retaining grease. This significantly extends the bearing's operational life, especially in harsh environments, and reduces maintenance needs.
Optimized Internal Clearance: The C3 clearance is a critical feature that accommodates dimensional changes from heat generation and press-fits. This prevents binding and overheating, ensuring stable performance and high operational reliability under varying thermal conditions.
High-Grade Material Construction: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing offers high hardness, wear resistance, and a long fatigue life, supporting its dynamic load rating of 2113 lbf.
Balanced Performance: The deep groove raceway and high-quality construction enable it to handle combined loads (radial and axial) efficiently. With a limiting speed of 17,000 rpm, it is well-suited for a broad spectrum of high-speed applications.
6004-2RSL/C3 Bearing Typical Application Areas
