2204 2RSTNH Bearing Product Overview & Core Advantages
The 2204 2RSTNH is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact, sealed construction offers high rigidity and operational reliability, making it an ideal choice for high-speed machinery where space is limited and maintenance access is difficult. The pre-lubrication and robust sealing ensure long service life with minimal upkeep.
2204 2RSTNH Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 2204 | Standard bearing designation indicating a 20 mm bore, 47 mm OD, and 18 mm width. |
| 2RS | Bearing is fitted with contact seals on both sides, providing superior protection against contamination. |
| TN | Indicates a Nylon (Polyamide) cage, which contributes to quiet operation, low friction, and is suitable for high speeds. |
| H | Signifies that the bearing is pre-lubricated with a high-quality grease suitable for the specified temperature range. |
2204 2RSTNH Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide high radial and axial stiffness, enabling the bearing to support substantial combined loads effectively.
- Superior Sealing & Longevity: The 2RS contact seals on both sides robustly shield the internal components from contaminants like dust and moisture, significantly extending the bearing's service life in harsh environments.
- Optimized High-Speed Performance: The lightweight Nylon (TN) cage reduces centrifugal forces, minimizes friction, and allows for a high limiting speed of 10,000 rpm, making it a true high-speed bearing.
- Maintenance-Free Operation: The combination of effective seals and factory-applied grease makes the bearing lubricated-for-life under normal operating conditions, reducing total cost of ownership.
