W 6204/W64 Bearing Product Overview & Core Advantages
The W 6204 is a single row deep groove ball bearing designed for reliable performance in a wide range of applications. Engineered with stainless steel rings and balls, it offers excellent corrosion resistance. A key feature is its Solid Oil lubrication, which provides long-term, maintenance-free operation by effectively retaining lubricant and excluding contaminants. This bearing is characterized by its high limiting speed and capability to handle primarily radial loads, making it a robust and durable choice for precision machinery.
Model Code Breakdown
- W 6204: Basic model number denoting a metric, single row deep groove ball bearing with a 20mm bore.
- No Sealing Suffix: The "Open" seal type indicates the bearing has no physical contact seals, minimizing friction for higher speeds.
- Solid Oil: The bearing is pre-lubricated with a polymer matrix saturated with oil, offering a clean, long-lasting lubrication solution.
- Implicit Tolerances: The bearing conforms to ABEC 1 | ISO P0 tolerance class and CN radial internal clearance as standard.
W 6204/W64 Bearing Structural Features & Performance Benefits
Corrosion Resistance: The use of stainless steel for both rings and balls makes this bearing ideal for applications exposed to moisture or corrosive environments, enhancing its service life.
Maintenance-Free Operation: The integrated Solid Oil lubrication system eliminates the need for re-lubrication, reduces maintenance costs, and prevents lubricant leakage, making it suitable for clean or hard-to-access areas.
High-Speed Capability: The open design, combined with the stable Solid Oil and a chrome steel cage, allows for a high limiting speed of 22,000 rpm, supporting demanding operational requirements.
Precision & Load Capacity: Manufactured to ABEC 1 precision standards, it ensures smooth and quiet running. With a dynamic load rating of 2428 lbf, it provides reliable performance under significant radial loads.
W 6204/W64 Bearing Typical Application Areas
The W 6204 is well-suited for a variety of industries and equipment, including:
- Food and Beverage Processing Machinery (due to stainless steel construction and Solid Oil)
- Medical and Dental Equipment
- Electric Motors and Small Gearboxes
- Conveyor Systems
- Precision Instruments and Office Automation Equipment
