МС 1420 OGH (SUMMER) GREASE FOR GEARS
MC 1420 OGH grease is designed for large heavy-loaded open and closed gears, sliding and rolling guides, plain bearings, pivots and joints of heavy mining machinery.
May be used in automatic centralized lubrication systems (ACLS), and is granted approval by Lincoln Company (SKF Concern), the biggest ACLS manufacturer.
Typical scope of application includes: single-bucket excavators (draglines or power shovels), toothing and drives of crushing/milling, kilning and agglomerative equipment, rail lubrication systems.
