ball bearing 6408 2rs zz

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 ball bearing 6408 2RS ZZ is a type of deep groove ball bearing that offers high precision and durability in various mechanical applications. Below is a detailed introduction to this type of bearing in English:

Overview

The ball bearing 6408 2RS ZZ is a radial ball bearing designed for supporting radial and axial loads in both directions. It features a deep groove geometry that allows for high-speed rotation and stable performance. The "2RS" and "ZZ" suffixes indicate the sealing configurations of the bearing.

Key Features

1. Dimensions:

• Inner Diameter: 40mm

• Outer Diameter: 110mm

• Width: 27mm

2. Sealing Configuration:

• 2RS: This suffix indicates that the bearing has two rubber seals on both sides. These seals protect the bearing from contaminants such as dust, dirt, and moisture, ensuring long-term performance and reliability.

• ZZ: This suffix indicates that the bearing has two metal shields on both sides. These shields also provide protection against contaminants but may offer less sealing capability compared to rubber seals.

3. Material and Construction:

• The bearing is made of high-quality bearing steel, ensuring durability and strength.

• The rolling elements (balls) are precision-manufactured to reduce friction and wear.

• The retainer holds the balls in place and prevents them from falling out of the bearing.

4. Load Capacity:

• The ball bearing 6408 2RS ZZ has a high load capacity, making it suitable for supporting radial and axial loads in both directions.

• The rated dynamic load capacity (Cr) and rated static load capacity (C0r) vary depending on the manufacturer and specific application.

5. Operating Conditions:

• The bearing can operate at high speeds and is suitable for both high-temperature and low-temperature environments.

• However, it is important to note that the operating conditions should not exceed the bearing's limits, as this may lead to premature failure.

Applications

The ball bearing 6408 2RS ZZ is widely used in various applications, including:

• Motors: It supports the rotation of motor shafts, ensuring smooth and efficient operation.

• Pumps: It is used in pumps to support the rotation of impellers and other rotating components.

• Fans: It provides support for fan blades, allowing them to rotate at high speeds without excessive vibration or noise.

• Machinery and Equipment: It is used in various machinery and equipment to support radial and axial loads, ensuring stable and reliable performance.

Maintenance and Care

To ensure the long-term performance and reliability of the ball bearing 6408 2RS ZZ, regular maintenance and care are essential. This includes:

• Lubrication: Regular lubrication is crucial to reduce friction and wear. The type and frequency of lubrication depend on the specific application and operating conditions.

• Inspection: Regular inspections should be conducted to check for signs of wear, damage, or contamination.

• Cleaning: The bearing should be cleaned regularly to remove any contaminants that may have entered the bearing.

• Replacement: If the bearing shows signs of excessive wear or damage, it should be replaced promptly to prevent further damage to the machinery.

In conclusion, the ball bearing 6408 2RS ZZ is a high-precision, durable deep groove ball bearing suitable for various mechanical applications. With its robust construction, high load capacity, and sealing configurations, it ensures smooth and efficient operation of machinery and equipment. Regular maintenance and care are essential to ensure its long-term performance and reliability.
