NTN 6317 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 NTN 6317 deep groove ball bearing is a high-quality, single-row bearing designed for a wide range of applications that require reliable, 

high-performance operation under both radial and axial loads. 

Manufactured by NTN, a globally recognized leader in bearing technology, this bearing is valued for its versatility, durability, 

and smooth operation, making it a popular choice across various industries.

Key Features:

Design and Construction: The NTN 6317 is a single-row deep groove ball bearing, featuring an inner ring, outer ring, a set of steel balls, 

and a cage that holds the balls in place. The deep groove design allows the bearing to handle both radial loads (forces perpendicular to the shaft) 

and axial loads (forces parallel to the shaft) in both directions. 

This makes it a highly versatile bearing suitable for a wide range of applications.

Dimensions: The NTN 6317 bearing has a bore diameter of 85 mm, an outer diameter of 180 mm, and a width of 41 mm. 

These dimensions make it a medium to large-sized bearing, typically used in applications requiring a moderate to high load capacity, 

such as industrial machinery, automotive parts, and electric motors.

Performance and Durability: The NTN 6317 bearing is engineered for high-speed operation, low friction, and reduced heat generation, 

making it ideal for applications where efficiency and long service life are important. 

NTN utilizes advanced materials and precision manufacturing techniques to ensure that the bearing delivers superior performance, 

even under demanding conditions. The bearing is designed to provide long-lasting service with minimal maintenance.

Sealing Options: The 6317 bearing is available in open and sealed versions. 

The open version allows for easy lubrication and is commonly used in environments where contamination is minimal, and external seals can be added if necessary. 

The sealed version has rubber seals on both sides, protecting the bearing from dirt, dust, and moisture, 

which helps to maintain the lubrication and prevent contaminants from entering the bearing.

Lubrication: The bearing is pre-lubricated with high-quality grease at the factory. 

Depending on the application, users can add additional lubrication as needed to maintain smooth operation and minimize wear. 

Proper lubrication is essential for preventing excessive friction and extending the bearing’s lifespan.

Applications: The NTN 6317 deep groove ball bearing is commonly used in a wide variety of applications, 

including electric motors, pumps, fans, compressors, gearboxes, and automotive components like wheel hubs and steering systems. 

Its ability to handle high-speed and moderate to heavy loads makes it suitable for both industrial and commercial applications.
