NTN 6404 deep groove ball bearing high speed

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 6404 deep groove ball bearing is a high-quality, single-row bearing designed to handle both radial and axial loads efficiently. 

It is known for its durability, smooth operation, and versatility, making it ideal for a wide range of industrial and automotive applications.

Design and Construction

The 6404 is a single-row deep groove ball bearing, consisting of an inner ring, outer ring, a set of steel balls, and a cage to keep the balls separated. 

Its deep groove design allows it to accommodate both radial loads (perpendicular to the shaft) and axial loads (along the shaft axis) in both directions. 

This design ensures smooth, low-friction performance, making it suitable for high-speed applications.

Dimensions

• Bore Diameter: 20 mm

• Outer Diameter: 52 mm

• Width: 15 mm

The 6404 is a medium-sized bearing, often used in light to medium-duty applications.

Performance and Durability

The 6404 deep groove ball bearing is designed for smooth, low-friction operation, reducing heat generation and wear. 

Made from high-quality materials, it offers excellent resistance to fatigue and long service life, even under moderate loads and speeds.

Applications

The 6404 deep groove ball bearing is commonly used in applications such as electric motors, pumps, fans, machine tools, and automotive components.

The 6404 deep groove ball bearing is a versatile and reliable choice for various applications. 

Its ability to handle both radial and axial loads, combined with its smooth operation and durability, 

makes it ideal for use in a wide range of machinery and equipment.
