Deep groove ball bearing SKF 6208 TN9/DBGA, Outer diameter: 80 mm | Width: 36 mm | Inner diameter: 40 mm

Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep groove ball bearings stand out for their versatility, ability to operate at high speeds, and low maintenance requirements.

This deep-groove ball bearing is designed to perform optimally in specific mounting configurations. This bearing is specially suited for demanding applications that require both high radial load capacity and resistance to axial loads in both directions. It features an O-arrangement (back-to-back mounting) and light preload, which ensure high rigidity and reduced vibration, making it ideal for precision and dynamic environments.

Features:
This bearing is designed with an O-arrangement (back-to-back mounting), in which two bearings are mounted opposite each other, back-to-back. This configuration increases the distance between the load centers, allowing for better distribution of axial loads in both directions and a high capacity to withstand high radial loads. It also provides increased resistance to tilting moments, ensuring optimal stability even under varying loads. The light preload applied in this arrangement provides high rigidity, minimizes internal play, and improves operational precision. Additionally, the reinforced polyamide cage ensures quiet operation, reduces friction, and contributes to better energy efficiency. Its lightweight design also helps reduce the total weight of the bearing and absorb shocks, making it ideal for dynamic applications.

Maintenance:
Maintenance of this bearing primarily involves regular greasing to ensure proper lubrication and prevent premature wear. The choice of grease depends on the load conditions and operating temperature. Visual inspection and vibration analysis allow for early detection of any failure. The bearing is optimized to operate at moderate temperatures, and it is important to monitor temperature fluctuations to prevent damage.

Sealing:
This bearing does not have a built-in seal and is therefore not protected against dust, contaminants, or lubricant leaks. This lack of sealing minimizes internal friction but requires appropriate maintenance measures to extend the bearing’s service life.
