Lubricants perform different roles across industrial equipment, from transmitting hydraulic power and separating moving surfaces to carrying away heat, controlling friction and protecting against corrosion. In specialised applications, they also provide electrical insulation or help maintain a vacuum seal.
Products with similar viscosity are not necessarily interchangeable. Base oil type, additive chemistry, water separation, thermal stability, material compatibility and electrical properties also matter. Select lubricants according to equipment design, operating conditions and manufacturer specifications.
Hydraulic oils transmit power while lubricating pumps, valves and cylinders. Selecting a suitable oil helps maintain viscosity, protect components against wear and support reliable operation as temperatures and loads change.
• Reliable hydraulic power transmission
