6204 ETN9 Bearing Product Overview & Core Advantages
The 6204 ETN9 is a single row deep groove ball bearing engineered for precision and reliability in demanding applications. This metric bearing features a P6 tolerance class for high running accuracy and a CN radial internal clearance, making it ideal for applications requiring precise shaft guidance. Its open design allows for versatile lubrication options, while the nylon cage (TN9) contributes to low friction, quiet operation, and suitability for high-speed operation up to 20,000 rpm. The combination of high-grade chrome steel components ensures excellent durability and a long service life under radial loads.
6204 ETN9 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6204 ETN9 is decoded as follows:
- 6204: Basic series designation, indicating a single row deep groove ball bearing with a 20mm bore, 47mm OD, and 14mm width.
- E: Signifies an optimized internal design, typically featuring reinforced structure and more or larger balls, resulting in a significantly higher dynamic load rating.
- TN9: Denotes the cage type and material. T indicates a pressed cage, and N9 specifies that it is made from glass fiber reinforced polyamide 66 (nylon). This cage is lightweight, promotes low operating temperatures, and is excellent for high speeds.
6204 ETN9 Bearing Structural Features & Performance Benefits
- High Load Capacity: The E-type internal design incorporates a larger ball complement and optimized raceway geometry, substantially increasing the radial dynamic load rating (3507 lbf) and static load rating (1720 lbf) compared to standard designs.
- High-Speed Performance: The lightweight and self-lubricating nylon TN9 cage minimizes centrifugal forces and friction, enabling smooth operation at the limiting speed of 20,000 rpm.
- Precision & Rigidity: Manufactured to a P6 tolerance class, this bearing ensures minimal runout and precise rotational accuracy. The deep groove raceways and robust construction provide high radial rigidity.
- Versatile Application: The open seal type allows for the use of various lubricants tailored to specific operating conditions (temperature, speed), offering flexibility for custom lubrication solutions.
6204 ETN9 Bearing Typical Application Areas
The 6204 ETN9 is widely used in applications that demand high precision, speed, and reliability. Key sectors include:
- Electric Motors and Small Appliance Motors
- Precision Gearboxes and Power Transmission Systems
- Industrial Pumps and Fans
- Machine Tool Spindles and CNC Machinery
- Automotive Components (e.g., alternators, idler pulleys)
