Circulating Oils

Circulating Oils – Reliable Lubrication for Continuous-Running Systems

LUBELINE™ supplies premium Circulating Oils designed to protect industrial equipment operating under continuous load. From turbines and paper machines to large bearings and process equipment, our oils help ensure smooth operation, efficient heat control, and long-term equipment reliability.

The Role of Circulating Oils

Industrial Circulating Oils are formulated for systems where oil is continuously pumped, filtered, and recirculated through machinery. These lubricants help to:

  • Deliver excellent oxidation stability for longer oil life
  • Protect against rust, corrosion, and varnish formation
  • Improve heat transfer in high-speed applications
  • Maintain system cleanliness for uninterrupted operation

Using high-quality Circulating Lubricants helps reduce downtime, minimise maintenance costs, and extend the lifespan of critical industrial equipment.

Common Applications of Circulating Oils

Paper Machines

  • Protect gears and bearings under continuous load
  • Reduce wear in high-speed, high-moisture environments

Steam & Gas Turbines

  • Lubricate and cool bearings and seals
  • Maintain stability under extreme heat and long operating cycles

Large Bearings & Rotating Machinery

  • Provide reliable lubrication under high pressure and temperature
  • Support smooth operation of heavily loaded bearings

Continuous-Process Equipment
