Bearing PFI 6800-2RS C3

The Deep Groove Ball Bearing, known as 61800-2RS-C3-PFI PFI, has an inner diameter of 10 mm, an outer diameter of 19 mm and a thickness of 5 mm.

The “2RS” suffix refers to a specific sealing configuration commonly found in deep groove ball bearings. It signifies that the bearing is equipped with two rubber seals on both sides, providing enhanced protection against contaminants and ensuring improved sealing performance. These seals help to retain lubrication within the bearing and prevent the ingress of dust, dirt, and moisture, thereby prolonging the bearing’s lifespan and maintaining its optimal performance.

C3 bearing suffix refers to the internal clearance level of a ball bearing. Specifically, C3 clearance indicates a greater clearance between the rolling elements and the inner and outer raceways compared to standard clearance. This increased clearance allows for thermal expansion and compensates for operating conditions with higher temperatures or slight misalignment.

The C3 clearance is suitable for applications where there may be thermal variations or situations that require a small amount of axial movement. It helps to prevent excessive heat generation and ensures optimal performance and longevity of the bearing in challenging operating environments.
