6204/MT47 Bearing Product Overview & Core Advantages
The 6204 is a single row deep groove ball bearing designed for exceptional performance in general industrial applications. This metric bearing excels at handling primarily radial loads and offers reliable operation within a wide temperature range. Its open design allows for versatile lubrication options, while the ABEC 1 (ISO P0) tolerance class ensures consistent quality and smooth running. The 6204 is characterized by its robust construction using chrome steel for all core components, providing excellent durability and a long service life.
6204/MT47 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6204 | Basic Bearing Series & Size | Denotes a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width. |
| Open (No Seal/Shield suffix) | No Integrated Seals or Shields | Enables high-speed operation and allows for custom lubrication regimes based on application needs. |
| ABEC 1 | ISO P0 | Standard Tolerance Class | Guarantees dimensional accuracy and running precision suitable for a vast majority of industrial uses. |
| CN Radial Clearance | Normal Internal Clearance | The standard clearance group, providing an optimal balance for general operating conditions. |
6204/MT47 Bearing Structural Features & Performance Benefits
The performance of the 6204 bearing is derived from its fundamental deep groove ball bearing design. The uninterrupted deep raceways on both rings enable it to support significant radial dynamic load ratings of up to 2878 lbf. The use of high-grade chrome steel for the rings, balls, and cage ensures high strength and resistance to wear. The open structure is key to its high-speed capability, with a limiting speed of 15,000 rpm, as it minimizes friction and heat generation. The standard CN radial internal clearance makes it versatile for a wide range of operating temperatures and fit conditions, ensuring reliable performance without the risk of binding or excessive play.
6204/MT47 Bearing Typical Application Areas
The 6204 is a versatile component found in numerous industrial sectors. Its primary applications include:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Material Handling Conveyors
- Agricultural Machinery
- Automotive Components (e.g., alternators, idler pulleys)
- General Machinery where reliable radial load support is required.
