The 6208 2RS deep groove ball bearing is a durable and reliable bearing solution designed for industrial applications that require stable operation, effective sealing, and long service life. As a single-row deep groove ball bearing with double rubber seals (2RS), this bearing is especially suitable for environments where protection against dust, moisture, and contaminants is essential.
The 6208 2RS bearing is engineered to handle high radial loads along with moderate axial loads in both directions, making it a versatile choice for a wide range of industrial machinery and mechanical systems.
Precision Engineering and Sealed Bearing Design
The 6208 2RS bearing is manufactured with precision-ground inner and outer rings and high-quality steel balls to ensure smooth rotation, low friction, and reduced vibration. Its deep groove raceway geometry allows even load distribution across the rolling elements, minimizing wear, internal stress, and heat generation during operation.
The bearing is equipped with double rubber seals on both sides, which effectively retain lubricant inside the bearing while preventing the ingress of dust, dirt, and moisture. This sealed design significantly reduces maintenance requirements and extends service life, making the 6208 2RS bearing ideal for continuous-duty and reliability-critical applications.
Technical Specifications of 6208 2RS Ball Bearing
The 6208 2RS 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 strong 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, enabling it to operate reliably under substantial radial loads while maintaining stable axial load support.
Regarding speed performance, the 6208 2RS 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. Although the presence of rubber seals slightly reduces the maximum achievable speed compared to open or shielded bearings, this trade-off delivers superior sealing performance, longer lubrication life, and improved operational reliability.
Typical Applications
Thanks to its sealed design, stable performance, and solid load-carrying capability, the 6208 2RS 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 pumps, fans, and compressors
-
Conveyor systems and material handling equipment
-
Agricultural and construction machinery
-
General industrial equipment
