6204-2Z/C3H-VM 104 Bearing Product Overview & Core Advantages
The 6204-2Z/C3H-VM 104 is a single row deep groove ball bearing engineered for high reliability in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while offering robust operational stability. The combination of shielded design and a C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where precise fits are required, ensuring consistent performance and extended service life.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6204 | Standard series designation for a single row deep groove ball bearing with a 20mm bore. |
| 2Z | Indicates shielded on both sides. This provides effective protection against contaminant ingress while minimizing friction. |
| C3 | Specifies a greater than normal radial internal clearance. Ideal for applications with shaft or housing fits that may reduce clearance, or where operational temperatures vary significantly. |
| H | Typically denotes a hardened cage, contributing to the bearing's overall durability. |
| VM 104 | Manufacturer-specific designation, often referring to a particular heat stabilization process that enhances dimensional stability at operating temperatures up to 120°C. |
6204-2Z/C3H-VM 104 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring high strength, wear resistance, and a long operational lifespan.
- Optimized Load Capacity: The deep groove raceway and robust construction enable it to carry significant radial dynamic loads (2878 lbf) and static loads (1495 lbf).
- Enhanced Operational Stability: The C3 clearance accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload and ensuring smooth running.
- Contaminant Protection: The double-shielded (2Z) design effectively seals the bearing against dust and debris, making it a maintenance-free solution for many applications.
- High-Speed Capability: With a limiting speed of 15,000 rpm, it is well-suited for a wide range of high-speed machinery.
6204-2Z/C3H-VM 104 Bearing Typical Application Areas
This versatile bearing is ideal for a broad spectrum of industrial equipment, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Systems (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
