Deep groove ball bearing SKF 6208-ZTN9/C3, Outer diameter: 80 mm | Width: 18 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 SKF deep groove ball bearing is designed to maintain low friction and deliver reliable performance at high rotational speeds. Its glass-fiber-reinforced polyamide cage and increased internal clearance (C3) make it a robust and durable solution.

Features:
This SKF bearing features a single row of balls and is made of glass-fiber-reinforced polyamide, which provides excellent mechanical strength while remaining lightweight. Thanks to its polymer cage and increased radial clearance (C3), this bearing has low friction and can therefore operate at high speeds. In addition, the C3 radial clearance promotes efficient heat dissipation, thereby protecting the polyamide cage. The integrated metal shield protects against large debris and limits lubricant loss on one side.

Maintenance:
The polyamide cage is corrosion-resistant, unlike metal cages. It also allows the bearing to operate temporarily with insufficient lubrication. Thanks to this cage and the increased internal clearance (C3), friction is minimized, which simplifies maintenance. However, since it has only a single metal shield, smaller contaminants can penetrate, and lubricant can escape from one side. It is therefore necessary to inspect the bearing occasionally and relubricate it. Because it is sealed on only one side, this allows for easier access for maintenance.

Sealing:
The metal shield protects the bearing from larger debris, but it is not effective against dust, small particles, and liquids. Lubricant loss may also occur since the bearing is sealed on only one side.

Brand Information:
SKF, founded in 1907, is a major player in the field of solutions for rotating equipment. Specializing in bearings, seals, and lubrication systems, the Swedish brand is recognized for its technical expertise and innovations that meet the diverse needs of industrial sectors such as automotive, aerospace, energy, and food processing.

Key Features:
- Low internal friction;
- Ability to operate at high rotational speeds;
- Good strength and elasticity, providing better resistance to shocks and vibrations;
- Protection against large contaminants thanks to the metal deflector;
- Lightweight design with a reinforced polyamide cage;
- Moderate maintenance and simplified servicing.

Applications:
These bearings are particularly well-suited for applications requiring high rotational speeds. They are used, in particular, in electric motors, in the automotive industry (transmissions, clutch systems, hubs), in industrial machinery (conveyors, compressors, pumps, fans, and machine tools), and in certain household appliances such as washing machines and dryers.
