Description
The SKF 6318/C3 is a high-quality single row deep groove ball bearing designed with an open configuration, making it well-suited for applications that rely on external lubrication and cooling during operation. Its C3 internal clearance provides additional room between the rolling elements and raceways, allowing for reliable performance in applications with higher operating speeds, thermal expansion, or elevated temperatures.
As part of the SKF Explorer performance class, the 6318/C3 delivers enhanced load-carrying capacity, reduced vibration and noise, lower friction, and extended service life compared to standard bearings. Capable of accommodating radial and axial loads in both directions, this bearing combines versatility and durability for dependable performance across a wide range of industrial machinery.
With its robust and easy-to-mount design, the SKF 6318/C3 is commonly used in motors, pumps, gearboxes, conveyors, and heavy-duty machinery, where consistent reliability and efficiency are essential.
