Description
Overview:
The K90 Calcium Sulphonate Complex Grease is a premium, heavy‐duty lubricant from Morris Lubricants designed for high loads and harsh environments. This genuine part uses a calcium sulphonate complex thickener with high‐quality base oil to deliver strong film strength, natural extreme‐pressure performance, and long service life. It resists water wash‐out, oxidation, and corrosion, helping protect bearings and sliding parts even in wet or dirty conditions. Supplied as a 400 g pack, it is well suited to routine maintenance on construction equipment and garden machinery, including excavators, loaders, compact tractors, and ride‐on mowers. Its wide operating temperature capability supports reliable lubrication from cold starts through sustained hot running, helping components stay efficient and reducing unplanned downtime.
