SKF 6321 deep groove ball bearing low price

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 SKF 6321 deep groove ball bearing is a high-performance, single-row bearing designed to accommodate 

both radial and axial loads in various industrial and automotive applications. 

Manufactured by SKF, a global leader in bearing technology, this bearing is known for its reliability, durability, 

and smooth operation, making it a popular choice for a wide range of demanding applications.

Key Features:

Design and Construction: The SKF 6321 is a single-row deep groove ball bearing consisting of an inner ring, outer ring, 

a set of steel balls, and a cage that holds the balls in position. 

The deep groove design enables the bearing to handle both radial loads (perpendicular to the shaft) and axial loads (parallel to the shaft) in both directions. This makes it suitable for high-speed operations and applications with moderate to heavy load requirements.

Dimensions: The SKF 6321 bearing has a bore diameter of 105 mm, an outer diameter of 225 mm, and a width of 49 mm. 

These dimensions place it in the medium to large size category, making it ideal for use in machinery that requires high load-carrying capacity 

and reliable performance under both radial and axial load conditions.

Performance and Durability: The SKF 6321 is designed for high-speed and low-friction operation. 

SKF's advanced manufacturing techniques and high-quality materials ensure the bearing can perform under demanding conditions, 

with minimal heat generation and wear. The bearing is engineered to provide long service life, reducing maintenance needs and downtime in various applications.

Sealing Options: The 6321 bearing is available in both open and sealed versions. 

The open version allows for easy lubrication and is ideal for environments where external sealing is provided or where the bearing operates in clean conditions. 

The sealed version comes with rubber seals on both sides, which help protect the bearing from contamination by dust, dirt, and moisture. 

The sealed version helps maintain the lubrication inside, reducing the need for frequent re-lubrication and enhancing the bearing’s performance in harsh environments.

Lubrication: The bearing is pre-lubricated with high-quality grease at the factory, ensuring smooth operation from the start. 

Depending on the application, additional lubrication can be added if necessary to ensure long-lasting performance and to reduce friction and wear.

Applications: The SKF 6321 deep groove ball bearing is used in a wide range of applications, including electric motors, pumps, fans, compressors, gearboxes, 

conveyors, and automotive components such as wheel hubs, axles, and steering systems. 

Its ability to handle high-speed rotations and both radial and axial loads makes it ideal for many industrial machinery and automotive applications.
