This Nilos seal ring sits between the bearing and the housing on a baler’s rotating shaft assembly. It functions as a contact seal, preventing dust and crop debris from entering the bearing cavity while retaining grease inside the bearing race. A worn or missing seal allows contamination to reach the rolling elements, leading to accelerated bearing wear and eventual shaft seizure. The ring is manufactured to match the original housing’s seal-groove profile so that it seats without distortion and maintains consistent lip pressure against the shaft. On installation, ensure the ring is pressed squarely into the groove and that the bearing is packed with fresh grease before reassembly.
