Deep groove ball bearing SKF 6203-2ZTN9/C3LHT23, Outer diameter: 40 mm | Width: 12 mm | Inner diameter: 17 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 deep groove ball bearing features a glass-fiber-reinforced polyamide cage and two metal shields that effectively protect against contaminants while retaining the lubricant inside. Thanks to its increased radial clearance (C3) and lifetime lubrication, it offers optimal performance and requires little maintenance, making it perfect for applications that demand speed and efficiency.

Features:
This single-row ball bearing features a glass-fiber-reinforced polyamide cage, which provides high speed, low density, and high elasticity. The C3 internal radial clearance, which is greater than that of standard models, promotes efficient heat dissipation and allows for higher rotational speeds. The two metal shields prevent the ingress of contaminants while retaining the lubricant. Pre-lubricated with lithium-thickened grease, this bearing is designed to operate between -55 and +140 °C.

Maintenance:
This deep-groove ball bearing requires very little maintenance thanks to its lifetime lubrication with high-quality grease. The metal seals provide long-lasting protection against contaminants, eliminating the need for relubrication. However, regular inspections are recommended to monitor the bearing’s condition, particularly in the event of unusual noise, excessive vibration, or signs of overheating.

Sealing:
To ensure a tight seal, the bearing is equipped with two metal shields that create a narrow passage. This helps limit the intrusion of contaminants, such as dust or medium-sized particles, while preventing lubricant leaks.

Brand Information:
