The 6307 2RS deep groove ball bearing is a robust and reliable bearing solution developed 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), it is specifically designed to operate in environments exposed to dust, moisture, and moderate contamination while maintaining consistent performance.
The 6307 2RS bearing is capable of carrying high radial loads together 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 6307 2RS bearing is manufactured with 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 optimal load distribution across the rolling elements, minimizing internal stress, wear, and heat generation during operation.
The bearing is fitted with double rubber seals on both sides, which securely retain lubricant inside the bearing while preventing the ingress of dust, dirt, and moisture. This sealed construction significantly reduces maintenance requirements and extends service life, making the 6307 2RS bearing well suited for continuous-duty and reliability-critical applications.
Technical Specifications of 6307 2RS Ball Bearing
The 6307 2RS deep groove ball bearing has an inner diameter of 35 mm, an outer diameter of 80 mm, and a width of 21 mm. With an approximate weight of 0.45 kg, it provides a strong and durable structure suitable for medium to heavy-duty industrial use.
In terms of load capacity, the bearing offers a dynamic load rating of 34 kN and a static load rating of 19.1 kN, allowing it to operate reliably under substantial radial loads while maintaining stable axial load support.
Regarding speed performance, the 6307 bearing can operate at speeds of up to 8,200 revolutions per minute when grease-lubricated and up to 9,900 revolutions per minute when oil-lubricated. Due to the presence of rubber seals, the practical operating speed may be slightly lower than open or shielded bearings; however, this is compensated by superior sealing performance, longer lubrication life, and improved overall reliability.
Typical Applications
Thanks to its sealed design, high load capacity, and stable performance, the 6307 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
