W 6004 Bearing Product Overview & Core Advantages
The W 6004 is a single row deep groove ball bearing designed for high performance in radial load applications. Manufactured entirely from stainless steel, it offers excellent corrosion resistance and is suitable for a wide temperature range from -30°C to 120°C. Its open design and P0 tolerance class ensure reliable operation and ease of integration into precision assemblies. This bearing is an ideal choice for applications demanding high rotational speeds, with a limiting speed of 24,000 rpm, and robust dynamic and static load ratings.
W 6004 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| W | Designates a stainless steel bearing series. |
| 6004 | Standard bearing size designation (20mm bore, 42mm OD, 12mm width). |
| Open (No Seal) | No contact seals, allowing for higher speeds and custom lubrication options. |
| P0 (Tolerance Class) | Standard dimensional and geometrical tolerance for general applications. |
| CN (Radial Clearance) | Normal radial internal clearance group. |
W 6004 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and optimized geometry minimize friction and heat generation, enabling a high limiting speed of 24,000 rpm, making it a capable high-speed bearing.
- Robust Load Capacity: Engineered with a deep groove raceway, it efficiently handles significant radial loads (1812 lbf dynamic, 1124 lbf static) and moderate axial loads in both directions.
- Corrosion Resistance & Cleanliness: Constructed entirely from stainless steel (rings, balls, and cage), it is inherently resistant to rust and corrosion, ideal for harsh environments, food processing, and medical equipment. It is compliant with ROHS and REACH directives.
- Precision & Reliability: Manufactured to P0 tolerance class with a controlled CN radial clearance, it ensures consistent performance, low noise, and smooth operation in precision mechanisms.
W 6004 Bearing Typical Application Areas
The W 6004 is widely used across various industries due to its stainless steel construction and high-speed performance. Key application areas include:
- Food and Beverage Processing Machinery (conveyors, mixers)
- Medical and Laboratory Equipment (small motors, pumps, diagnostic devices)
- Chemical and Pharmaceutical Machinery (where wash-downs and corrosion are concerns)
- Precision Instruments and Optical Devices
- Electric Motors and Gearboxes requiring corrosion-resistant components
