Deep groove ball bearing SKF 4208 ATN9/W64, Outer diameter: 80 mm | Width: 23 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, their ability to operate at high speeds, and their low maintenance requirements.

This SKF two-row deep groove ball bearing is designed to provide radial and axial load-carrying capacity in both directions. Easy to install, it features an open design that ensures easy access for maintenance and helps prevent component overheating. Ideal for high-speed applications and clean environments, it guarantees reliable performance while reducing internal friction for maximum energy efficiency.

Features:
Compared to a single-row deep groove ball bearing, this bearing offers excellent capacity to withstand high radial loads. Apart from its slightly greater width, its dimensions are similar (bore, diameter). Its design, featuring a glass-fiber-reinforced polyamide cage, provides increased strength while minimizing friction, thereby promoting smooth operation at high speeds. The absence of seals reduces friction levels and facilitates maintenance, but requires a clean environment for optimal operation.

Maintenance:
Maintenance of this ball bearing is minimal but essential to ensure optimal performance.
It is pre-lubricated at the factory with a grease called “Solid Oil,” a polymer developed by SKF that prevents moisture ingress and requires no maintenance. The absence of seals facilitates inspections and allows for regular checks of the condition of the balls and internal surfaces. Cleaning the external surfaces and checking the radial clearance are essential to prevent premature wear and maintain reliable long-term operation.

Sealing:
This SKF ball bearing does not have a built-in sealing system. Although this design allows for efficient cooling, the absence of seals means the bearing is exposed to external contaminants such as dust or liquid splashes. However, Solid Oil grease is water-repellent. It prevents water and moisture from penetrating the bearing. It is nevertheless best suited for clean, controlled environments.
