6004-2RSHTN9/C4HT Bearing Product Overview & Core Advantages
The 6004-2RSHTN9/C4HT is a single row deep groove ball bearing engineered for high performance in demanding applications. This sealed bearing is designed to primarily handle radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a robust construction using chrome steel rings and balls, a lightweight Nylon cage for smooth operation, and integrated sealing for long-term protection. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable precision and is pre-lubricated for immediate use, making it an ideal choice for applications requiring a compact, durable, and maintenance-friendly solution.
6004-2RSHTN9/C4HT Bearing Model Code Explained, Specifications & Naming Convention
- 6004: Basic designation indicating a metric, single row deep groove ball bearing with a 20mm bore and 42mm outside diameter.
- 2RS: Signifies that the bearing is equipped with contact seals on both sides. These seals provide superior protection against contaminants and retain lubricant effectively.
- H: Indicates the presence of a pressed steel cage (Note: This is a common interpretation, though the provided spec lists a Nylon cage. The "H" may refer to a specific cage design or material grade in this context).
- TN9: Denotes a glass fiber reinforced polyamide (Nylon) cage. This cage design is lightweight, allows for high speeds, and offers quiet operation with excellent guidance.
- C4: Specifies a greater radial internal clearance than the normal (CN) group. This is beneficial for applications with significant thermal expansion or where interference fits are used.
- HT: Represents a high-temperature lubricant suitable for the specified operating temperature range of -30°C to 120°C.
6004-2RSHTN9/C4HT Bearing Structural Features & Performance Benefits
Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction provide a high dynamic load rating of 2113 lbf and a static load rating of 1135 lbf, ensuring durability under significant radial stress.
Enhanced Sealing & Lubrication: The 2RS double-contact seals effectively shield the internal components from dust, moisture, and other contaminants, while retaining the high-temperature grease (HT). This combination delivers a long service life with minimal maintenance.
High-Speed Capability: The lightweight and robust Nylon TN9 cage minimizes centrifugal forces and friction, contributing to a high limiting speed of 17,000 rpm. The optimized internal geometry further supports smooth, high-velocity rotation.
Thermal Stability: The C4 radial internal clearance accommodates dimensional changes due to thermal expansion during operation, preventing preload and ensuring consistent performance across the specified temperature range.
6004-2RSHTN9/C4HT Bearing Typical Application Areas
