The 6209 2RS deep groove ball bearing is a robust and reliable bearing solution designed for industrial applications that require dependable operation, effective sealing, and extended service life. As a single-row deep groove ball bearing with double rubber seals (2RS), this bearing is particularly suitable for operating environments exposed to dust, moisture, and light contamination.
The 6209 2RS bearing is engineered to accommodate high radial loads together with moderate axial loads in both directions, making it a versatile and widely used bearing in industrial machinery and mechanical systems.
Precision Engineering and Sealed Bearing Design
The 6209 2RS bearing is manufactured using precision-ground inner and outer rings combined with high-quality steel balls to ensure smooth rotation, low friction, and reduced vibration. Its deep groove raceway geometry allows for even load distribution across the rolling elements, minimizing internal stress, wear, and heat generation during operation.
Equipped with double rubber seals on both sides, the bearing effectively retains lubricant while preventing the ingress of dust, dirt, and moisture. This sealed design significantly reduces maintenance requirements and helps extend service life, making the 6209 2RS bearing ideal for continuous-duty and reliability-critical applications.
Technical Specifications of 6209 2RS Ball Bearing
The 6209 2RS deep groove ball bearing has an inner diameter of 45 mm, an outer diameter of 85 mm, and a width of 19 mm. With an approximate weight of 0.40 kg, the bearing provides a strong and well-balanced structure suitable for medium-duty industrial applications.
In terms of load capacity, the bearing offers a dynamic load rating of 33.1 kN and a static load rating of 20.9 kN, allowing it to operate reliably under substantial radial loads while maintaining stable axial load support.
Regarding speed performance, the 6209 2RS bearing can operate at speeds of up to 7,500 revolutions per minute when grease-lubricated and up to 8,800 revolutions per minute when oil-lubricated. Although the presence of rubber seals slightly reduces maximum achievable speed compared to open or shielded bearings, this trade-off provides 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 6209 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
