6204-2ZNR/C3GJN Bearing Product Overview & Core Advantages
The 6204-2ZNR/C3GJN is a single row deep groove ball bearing designed for robust performance in demanding applications. Its key advantage lies in its integrated snap ring groove and shield combination, enabling simplified axial location and effective contamination protection. This bearing is engineered to primarily handle radial loads with high efficiency and is characterized by its standard C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Its construction from high-grade chrome steel ensures durability and reliable operation.
6204-2ZNR/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6204 | Basic Bearing Series & Size | Denotes a metric, single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. |
| 2Z | Shielded on Both Sides | Provides effective protection against contamination while allowing for higher limiting speeds compared to contact seals. |
| NR | Snap Ring Groove on Outer Ring | Facilitates easy axial location and secure mounting within a housing, reducing the need for complex housing designs. |
| C3 | Radial Internal Clearance | Indicates a clearance greater than normal (CN), suitable for applications with expected thermal gradients or interference fits. |
6204-2ZNR/C3GJN Bearing Structural Features & Performance Benefits
Optimized for Radial Loads and Secure Mounting: The single row deep groove raceway is precision-ground to handle significant radial dynamic and static loads (2878 lbf / 1495 lbf). The presence of the snap ring groove on the outer ring is a critical structural feature that provides a positive locating surface, enhancing assembly accuracy and system rigidity.
Enhanced Contamination Protection: The non-contact Z-shields on both sides protect the bearing's internal components from dust and larger particles without generating significant friction, contributing to the high limiting speed of 15,000 rpm.
Robust Material Construction: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing offers high strength, wear resistance, and a long operational life under standard conditions.
Precision and Versatility: Built to ABEC 1 | ISO P0 tolerance class, it ensures consistent performance for a wide range of industrial applications. The specified C3 clearance provides operational flexibility in environments prone to thermal expansion.
6204-2ZNR/C3GJN Bearing Typical Application Areas
The 6204-2ZNR/C3GJN is ideally suited for applications requiring reliable radial load support, simplified mounting, and basic contamination protection. Key sectors include:
- Electric Motors and Gearboxes: Where the snap ring simplifies housing design and the shields protect against debris.
- Industrial Fans and Blowers: Benefiting from the bearing's capability for higher rotational speeds.
- Material Handling Equipment: Such as conveyor pulleys, where secure axial location is critical.
- Agricultural Machinery: Providing a durable solution in moderately contaminated environments.
- General Machinery and Automotive Auxiliaries: A versatile choice for pumps, compressors, and idler pulleys.
