Deep groove ball bearing SKF 6308-Z/C3, Outer diameter: 90 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, ability to operate at high speeds, and low maintenance requirements.

This SKF-brand deep groove ball bearing stands out for its versatility, capable of handling both radial and axial loads, making it suitable for a wide range of applications across various industries. Its specialized design provides effective protection against contaminants while maintaining low internal friction. This ensures optimal performance, even at high speeds.

Features:
This single-row deep groove ball bearing, made of sheet steel, features a metal shield and C3 internal radial clearance. It is particularly well-suited for applications requiring high rotational speeds while maintaining low internal friction. Its internal structure allows it to withstand heavy radial loads as well as moderate axial loads. Its sheet steel cage offers good resistance to constant loads while tolerating shocks and momentary loads, making it a robust and versatile choice. Its design enables smooth and efficient operation while requiring minimal maintenance.

Maintenance:
The low friction level, due to the increased C3 clearance, reduces the frequency of maintenance on this bearing. Maintenance is also simplified thanks to its metal deflector, which protects against contaminants while limiting lubricant loss on one side. However, regular inspections are recommended to ensure optimal operation, which is facilitated by access to its second open side. In addition, it is essential to monitor noise and vibration levels, which may indicate the need for maintenance.

Sealing:
The metal deflector integrated into this bearing provides partial sealing against solid contaminants, while blocking the infiltration of larger debris. However, this protection does not completely block moisture, which can increase the risk of corrosion. On the other hand, the deflector causes only minimal lubricant loss, thus ensuring effective protection while maintaining the bearing’s performance.
