W 6304-2Z Bearing Product Overview & Core Advantages
The W 6304-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Constructed entirely from stainless steel, it offers superior corrosion resistance. Its key advantage lies in its ability to handle significant radial loads while also accommodating moderate axial loads in both directions. The integrated shielded design (2Z) and pre-greased lubrication provide robust contamination protection and long-term, maintenance-free operation, making it an ideal choice for applications requiring high reliability and durability.
W 6304-2Z Bearing Model Code Explained, Specifications & Naming Convention
The model designation W 6304-2Z can be broken down as follows:
- W: Designates a specific series or manufacturer's prefix.
- 63: Indicates the bearing series, defining the dimensional boundary.
- 04: Specifies the bore diameter; code '04' corresponds to a 20 mm bore (04 x 5 = 20 mm).
- 2Z: Signifies that the bearing is shielded on both sides. This provides effective protection against contaminants while allowing for high-speed operation.
W 6304-2Z Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from stainless steel rings, balls, and cage, this bearing delivers excellent corrosion resistance and is suitable for a wide temperature range from -30° to 120 °C.
- High Load Capacity: With a dynamic load rating of 3102 lbf and a static load rating of 1754 lbf, it is engineered to handle substantial radial loads reliably.
- Optimized for Speed: The stainless steel cage and shielded design contribute to a high limiting speed of 17,000 rpm.
- Maintenance-Free Operation: The combination of shields on both sides (2Z) and pre-applied grease lubrication seals in the lubricant and seals out debris, ensuring long service life without the need for re-lubrication.
- Standard Tolerances: Manufactured to P0 tolerance class and standard CN radial internal clearance, ensuring consistent and reliable performance for a wide array of applications.
W 6304-2Z Bearing Typical Application Areas
The W 6304-2Z is ideally suited for applications where corrosion resistance, high speed, and minimal maintenance are critical. Key sectors include:
- Food and Beverage Processing Equipment
- Medical and Pharmaceutical Machinery
- Chemical Handling Pumps and Mixers
- Electrical Motors and Small Gearboxes
- Agricultural and Marine Equipment
