6204/MT Bearing Product Overview & Core Advantages
The 6204 single row deep groove ball bearing is a fundamental component in rotating machinery, engineered for high reliability and efficient operation. As an open-type radial bearing, it excels in applications requiring smooth, low-friction rotation under primarily radial loads. Its standardized metric dimensions (20mm bore, 47mm OD) and ABEC 1 (ISO P0) tolerance class make it a versatile and cost-effective solution for a vast range of industrial equipment, offering a robust balance of performance and durability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 62 | Series code indicating a medium-duty, single row deep groove ball bearing with a standard width. |
| 04 | Bore diameter code. For a 62 series bearing, this corresponds to a 20mm bore diameter. |
| Open (No Seal/Shield suffix) | The bearing is supplied without seals or shields, allowing for high-speed operation and facilitating re-lubrication. It is suitable for clean environments or where external sealing is provided. |
6204/MT Bearing Structural Features & Performance Benefits
- Optimized Radial Load Capacity: The uninterrupted deep groove raceways and high-quality chrome steel construction enable the 6204 to handle significant radial dynamic loads (2878 lbf) and static loads (1495 lbf) efficiently.
- High-Speed Capability: The open design and standard chrome steel cage minimize friction and allow for a limiting speed of 15,000 rpm, making it suitable for demanding high-RPM applications.
- Standard Precision & Internal Clearance: Manufactured to ABEC 1 (ISO P0) tolerance standards with a CN (Normal) radial internal clearance, this bearing provides consistent, reliable performance for general industrial use.
- Material Integrity: Constructed entirely from chrome steel for the rings, balls, and cage, ensuring high strength, wear resistance, and a broad operating temperature range (-30°C to 120°C).
6204/MT Bearing Typical Application Areas
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
