6306z 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 6306Z bearing is a single-row deep groove ball bearing with a single metal shield on one side. Here is a detailed introduction to the 6306Z bearing in English:

1. General Description:

• The 6306Z bearing is designed to handle both radial and axial loads, although it is primarily used for applications involving radial loads. It is known for its low noise and low vibration, enabling high rotational speeds.

2. Technical Specifications:

• Bore Diameter (d): 30 mm

• Outer Diameter (D): 72 mm

• Width (B): 19 mm

• Dynamic Load Rating (Cr): Approximately 42.5 kN

• Static Load Rating (C0r): Approximately 27.5 kN

• Limiting Speed: Varies depending on the specific bearing design and lubrication conditions, but typically in the range of several thousand RPMs

3. Design Features:

• The bearing has a deep groove raceway design that provides a large load-carrying capacity and allows for high-speed operation.

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

• The "Z" in the model number indicates that the bearing has a single metal shield on one side to protect the bearing from dust and other contaminants, while also helping to retain lubricant.

4. Applications:

• The 6306Z 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 shielded design of the 6306Z bearing reduces the need for frequent maintenance, as the shield protects 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 shield 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 6306Z bearing comes in various variants, including those with different sealing options, such as the 6306-2RS version, which has two rubber seals, providing additional protection against contaminants and helping to retain lubricants.

8. Quality Assurance:

• Bearings from reputable manufacturers undergo rigorous quality control processes to ensure they meet the highest standards of performance and reliability.

The 6306Z bearing's combination of high load ratings, high-speed capabilities, and shielded protection make it a popular choice for a wide range of applications where reliability and performance are critical.
