NSK 6304 deep groove ball bearing high precision

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 sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed  makes radial and axial loads in both directions, so it requires little maintenance.

The NSK 6304 Deep Groove Ball Bearing is a versatile and durable bearing widely used in various industrial and mechanical applications. 

As part of NSK’s extensive range of deep groove ball bearings, 

the 6304 model is designed to provide smooth operation, high load capacity, and long-lasting performance. 

This bearing type is ideal for handling both radial and axial loads, making it suitable for a broad spectrum of applications.

Design and Specifications

The NSK 6304 bearing features an inner diameter of 20 mm, an outer diameter of 52 mm, and a width of 15 mm. 

These dimensions make it ideal for medium to large-sized applications that require a balance of load-carrying capacity and compact design. 

The deep groove structure allows the bearing to support radial loads as well as axial loads in both directions, offering exceptional versatility.

The bearing’s design ensures smooth, low-friction operation, reducing heat generation during high-speed rotation. 

This results in improved efficiency and extends the overall lifespan of the bearing. 

Additionally, the 6304 bearing is capable of handling slight misalignments, which contributes to its reliability in dynamic and varying load conditions.

Materials and Construction

The NSK 6304 bearing is made from high-quality chrome steel or carbon steel, ensuring excellent resistance to wear, corrosion, and fatigue. 

The inner and outer rings are precision-machined for smooth raceway and the steel balls are evenly spaced by a cage, typically made of steel or brass. This cage design helps reduce friction and maintain proper ball alignment, 

ensuring smooth operation and contributing to the bearing’s extended service life.

The bearing can also come with sealing options, such as rubber seals or metal shields, to protect it from dirt, moisture, and other contaminants. 

These seals enhance the bearing’s performance in harsh environments and minimize the need for maintenance.

Applications

The NSK 6304 deep groove ball bearing is used in various applications, including:

Electric motors: Commonly found in motors for industrial equipment, household appliances, and power tools, where smooth operation and high-speed performance are crucial.

Automotive components: Used in wheel hubs, alternators, and other automotive systems that require reliable, long-lasting performance.

Industrial machinery: Ideal for pumps, compressors, conveyors, and other machinery requiring high load capacity and efficient operation.

Household appliances: Suitable for washing machines, air conditioners, and fans, where durability and low maintenance are important.

Advantages

Durability: High-quality materials provide excellent resistance to wear and corrosion, extending the bearing’s service life.

Versatility: The bearing can handle both radial and axial loads, making it suitable for a variety of applications.

Low Friction: The deep groove design minimizes friction, leading to smoother operation and improved efficiency.

Protection: Sealing options protect the bearing from contaminants, reducing maintenance and increasing reliability.
