NACHI 6318 deep groove ball bearing orginal imported

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 NACHI 6318 deep groove ball bearing is a high-quality, single-row bearing designed to accommodate both radial and axial loads. 

Manufactured by NACHI, a well-respected global bearing manufacturer, this bearing is known for its reliability, durability, 

and smooth operation in various industrial and commercial applications.

Key Features:

Design and Construction: The NACHI 6318 is a single-row deep groove ball bearing,

 which consists of an inner ring, an outer ring, a set of steel balls, and a cage to retain the balls in position. 

This design allows the bearing to handle radial loads (forces perpendicular to the shaft) and axial loads (forces along the shaft axis) in both directions. 

Its deep groove shape allows for smooth rotation, minimal friction, and effective load distribution, making it ideal for high-speed applications.

Dimensions: The NACHI 6318 bearing features a bore diameter of 90 mm, an outer diameter of 190 mm, and a width of 43 mm. 

These dimensions make it a medium to large-sized bearing, 

suitable for use in applications requiring a moderate to high load capacity and reliability over extended periods of operation.

Performance and Durability: The NACHI 6318 is designed for long service life and minimal maintenance. 

It is constructed with high-quality materials that provide resistance to wear and tear, even under demanding conditions. 

This bearing is engineered to offer excellent performance in high-speed operations while maintaining low friction and heat generation, ensuring smooth, 

efficient functioning throughout its lifespan.

Sealing Options: The 6318 bearing is available in both open and sealed versions. 

The open version allows for easy lubrication and is suitable for environments where external sealing can be managed. 

The sealed version, on the other hand, features rubber seals on both sides, preventing contamination from dust, dirt, 

and moisture, and helping to retain lubrication inside the bearing for longer periods, which is beneficial for harsh operating conditions.

Lubrication: The bearing is typically pre-lubricated with high-quality grease during manufacturing. 

Depending on the application requirements, additional lubrication may be applied to ensure smooth operation, reduce friction, and extend the bearing's service life.

Applications: The NACHI 6318 deep groove ball bearing is widely used in various industrial and automotive applications, 

including electric motors, pumps, fans, compressors, machine tools, and conveyors. 

Its ability to handle moderate to heavy loads and its efficiency in high-speed operations make it a reliable choice for many mechanical systems.
