Deep groove ball bearing SKF 4310 ATN9, Outer diameter: 110 mm | Width: 40 mm | Inner diameter: 50 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.

Double-row deep groove ball bearings function as two single-row bearings combined. Their robust construction allows for minimal maintenance, high speeds, and the ability to handle radial and axial loads in both directions. Although they are slightly wider than single-row models of similar dimensions, they offer significantly higher load capacity.

Features:
This deep groove ball bearing features a double-row ball design. It has a glass-fiber-reinforced polyamide 6.6 cage centered over the rollers, ensuring both strength and flexibility. Thanks to its good sliding properties, the polymer cage induces low friction and thus allows for high speeds. Under poor lubrication conditions, this cage reduces the risk of seizure and secondary damage. Its standard internal radial clearance (CN) ensures stable performance. The absence of seals results in very low resistance torque, thereby minimizing resistance to movement. However, it is not protected against external contaminants. This bearing is also capable of operating within moderate temperature ranges, limited by the polyamide cage.

Maintenance:
Maintenance of this deep groove ball bearing is essential to ensure its optimal performance and longevity. Since it is open, it requires regular lubrication to prevent premature wear. A maintenance program should include frequent inspections to check for noise, temperature, and the condition of the balls and raceways.

Sealing:
This bearing has no sealing against external contaminants, such as dust and particles. Although this open design facilitates access for maintenance and cooling, it also makes the bearing vulnerable to the intrusion of contaminants, which can lead to lubricant leakage. It is therefore essential to use it in clean, controlled environments to prevent damage. This lack of sealing has the advantage of minimizing resistance to movement, but requires special attention to lubrication.
