The Nilos Ring 1215AV is a high-quality labyrinth seal designed to protect bearings from dirt, dust, moisture, and other contaminants. This non-contact seal creates a narrow gap that prevents ingress of foreign particles while retaining lubricant, significantly extending bearing service life and reducing maintenance. It is specifically engineered for use with bearings having an inner diameter of 75 mm and an outer diameter of 130 mm, providing reliable protection in demanding industrial and agricultural applications.
