The 6208 ZZ deep groove ball bearing is a reliable and widely used bearing designed for applications that require smooth operation, low friction, and protection against solid contaminants. As a single-row deep groove ball bearing with double metal shields (ZZ), it is ideal for relatively clean operating environments where higher rotational speeds and long service life are essential.
The 6208 ZZ bearing is engineered to support high radial loads together with moderate axial loads in both directions, making it a versatile solution for many industrial and mechanical applications.
Precision Engineering and Shielded Bearing Design
The 6208 ZZ bearing is manufactured with precision-ground inner and outer rings and high-quality steel balls to ensure smooth rotation, low noise, and reduced vibration. Its deep groove raceway geometry allows even load distribution across the rolling elements, minimizing internal stress, wear, and heat generation during operation.
Equipped with double metal shields on both sides, the bearing effectively protects against dust and solid particles while retaining lubricant inside the bearing. The non-contact shield design enables higher operating speeds compared to sealed bearings, while still providing reliable contamination protection.
Technical Specifications of 6208 ZZ Ball Bearing
The 6208 ZZ deep groove ball bearing has an inner diameter of 40 mm, an outer diameter of 80 mm, and a width of 18 mm. With an approximate weight of 0.35 kg, the bearing offers a robust and well-balanced structure suitable for medium-duty industrial applications.
In terms of load capacity, the bearing provides a dynamic load rating of 31.4 kN and a static load rating of 18.9 kN, allowing it to operate reliably under substantial radial loads with stable axial load support.
Regarding speed capability, the 6208 ZZ bearing can operate at speeds of up to 8,100 revolutions per minute when grease-lubricated and up to 9,500 revolutions per minute when oil-lubricated. This makes it well suited for applications that require efficient performance at moderate to high speeds.
Typical Applications
Thanks to its shielded design, balanced load capacity, and stable performance, the 6208 ZZ deep groove ball bearing is commonly used in a wide range of industrial and mechanical applications, including:
-
Electric motors and industrial generators
-
Gearboxes and transmission systems
-
Industrial fans and blowers
-
Pumps and compressors
-
Conveyor systems and material handling equipment
-
General industrial machinery
