NTN Orginal Deep Groove Ball Bearings 6004

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.Integral sea

The NTN Original Deep Groove Ball Bearing 6004 is a high-quality, versatile bearing designed for a wide range of industrial 

and mechanical applications. As part of NTN's extensive range of deep groove ball bearings, the 6004 model is renowned for its durability, precision, 

and cost-effectiveness. These bearings are used in various sectors, including automotive, machinery, electrical motors, 

and household appliances, where efficient performance and reliability are essential.

Design and Specifications

The NTN 6004 deep groove ball bearing features an inner diameter of 20 mm, an outer diameter of 42 mm, and a width of 12 mm. 

This size makes it suitable for applications where compactness and high load capacity are necessary. 

The bearing's deep groove design allows it to support radial loads, which are perpendicular to the shaft, as well as axial loads, 

which are parallel to the shaft in both directions. This versatility makes the 6004 bearing ideal for a variety of mechanical systems and applications.

The deep groove ball bearing design is characterized by its smooth and continuous raceway,

which reduces friction during rotation, allowing for high-speed operation with minimal wear. 

Additionally, the bearing is capable of handling moderate radial and axial loads, 

making it suitable for general-purpose applications where space is limited but high performance is required.

Materials and Construction

NTN manufactures the 6004 bearing using high-quality steel, typically chrome steel (AISI 52100) or carbon steel, 

which ensures excellent durability and resistance to wear and fatigue under normal operating conditions. 

The steel is also treated to offer resistance against corrosion, improving the bearing's performance in environments.

The 6004 bearing consists of an inner ring, an outer ring, balls, and a cage. 

The steel balls are precision-machined to ensure smooth rotation, and the cage (often made of steel or brass) is used to maintain proper spacing between the balls. 

The cage reduces friction and ensures smooth ball movement, preventing direct contact between the balls and minimizing heat generation during operation.

Applications

The NTN 6004 deep groove ball bearing is used in a variety of industries and applications, including:

• Electric motors: Widely used in small electric motors where high-speed operation and low maintenance are crucial.

• Automotive components: Used in car engines, wheels, pumps, and gearboxes.

• Industrial machinery: Found in conveyors, pumps, and compressors, the bearing supports both radial and axial loads in various machines.

• Household appliances: Commonly used in devices like washing machines, fans, and refrigerators due to its low maintenance and smooth operation.

Advantages

1. High Durability: The 6004 bearing is made of high-quality materials that enhance its lifespan and provide resistance to wear and corrosion.

2. Versatility: Suitable for both radial and axial load applications, making it highly adaptable for a wide range of uses.

3. Smooth Operation: The deep groove design ensures reduced friction, enabling efficient high-speed rotation and quiet operation.

4. Sealing Options: The sealed and shielded options provide flexibility, allowing users to select the best configuration for their environment and load conditions.

5. Low Maintenance: NTN's high-quality construction and sealing options reduce the need for frequent maintenance or lubrication.
