Deep groove ball bearing SKF 6204 TN9/C4, Outer diameter: 47 mm | Width: 14 mm | Inner diameter: 20 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 deep-groove ball bearing, with its glass-fiber-reinforced polyamide cage, is designed to withstand very high speeds, even under load. Ideal for demanding applications, it minimizes friction and heat generation to ensure smooth rotation and provide increased durability.

Features:
This single-row rigid ball bearing is equipped with a glass-fiber-reinforced polyamide cage, which provides high strength and reduces friction, even at high speeds. Its C4-type internal radial clearance allows for a greater range of motion, which helps prevent seizing or jamming of the rolling elements even under high loads. The low friction also generates less heat, while its open design promotes efficient heat dissipation.

Maintenance:
To ensure optimal performance, regular maintenance is essential. Its open design allows for easy periodic inspections and lubrication. Its reinforced polyamide cage enables it to operate with a small amount of lubricant, thereby reducing the risk of seizing. However, it is recommended to maintain adequate lubrication using a high-quality lubricant suitable for the operating conditions. Regular checks of noise, temperature, and radial play are crucial for detecting signs of premature wear and taking prompt action.

Sealing:
This bearing model has no sealing system, leaving it completely exposed to the external environment. This lack of protection means it is not shielded from contaminants such as dust or liquids, which can lead to dirt ingress and lubricant leakage. On the other hand, this open design allows for excellent heat dissipation and direct access for maintenance, which is advantageous in clean, controlled environments.
