double seals 6307rs bearing

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 sea

The NTN 6307RS bearing, also known as the SKF 6307-2RS1, is a single-row deep groove ball bearing with double seals on both sides, providing enhanced protection against contaminants and better retention of lubricants. Here is a detailed introduction to the SKF 6307-2RS1 bearing in English:

1. General Description:

• The SKF 6307-2RS1 bearing is a deep groove ball bearing that is particularly versatile, with low friction and optimized for low noise and low vibration, which enables high rotational speeds. It accommodates radial and axial loads in both directions, is easy to mount, and requires less maintenance than many other bearing types. The double seals significantly prolong the bearing's service life by preventing lubricant leakage and keeping contaminants out.

2. Technical Specifications:

• Bore Diameter (d): 35 mm

• Outer Diameter (D): 80 mm

• Width (B): 21 mm

• Dynamic Load Rating (Cr): 35.1 kN

• Static Load Rating (C0r): 19 kN

• Limiting Speed: 6,000 RPM

• SKF Performance Class: SKF Explorer

3. Design Features:

• The bearing has a simple, robust design with a single row of deep grooves that accommodate a large number of balls, providing high load-carrying capacity and allowing for high-speed operation.

• It is made from high-quality bearing steel, ensuring durability and reliability.

• The double seals are contact-style, which means they provide a closer fit to the outer ring, enhancing sealing effectiveness.

4. Applications:

• The SKF 6307-2RS1 bearing is commonly used in electric motors, pumps, fans, gearboxes, and other machinery where high performance and reliability are required.

• It is suitable for applications in the automotive, agricultural, and industrial sectors where bearings are subjected to dirt, dust, and other contaminants.

5. Maintenance:

• The sealed design of the SKF 6307-2RS1 bearing reduces the need for frequent maintenance, as the seals protect the bearing from dirt and moisture.

• However, it's still important to ensure that the bearing is not overtightened or misaligned during installation, as this can damage the seals and reduce the bearing's lifespan.

6. Installation:

• Proper installation is crucial for the bearing's performance and lifespan. It is recommended to use the correct tools and follow best practices to avoid damage during installation.

• The bearing should be cleaned, and the mating surfaces should be free of contaminants before installation.

7. Variants:

• The SKF 6307-2RS1/HC5C3GJN is a variant of this bearing that features hybrid ceramic technology, with rings made of bearing steel and rolling elements made of bearing grade silicon nitride. This makes the bearings electrically insulating and provides protection from electric current damage. The integral sealing prolongs bearing service life, and the ceramic rolling elements offer enhanced performance and extended service life, especially in difficult conditions and contaminated environments.

8. Quality Assurance:

• SKF bearings, including the 6307-2RS1, are known for their high quality and are manufactured to stringent quality standards, ensuring reliability and performance.

The SKF 6307-2RS1 bearing's combination of high load ratings, high-speed capabilities, and sealed protection make it a popular choice for a wide range of applications where reliability and performance are critical
