Mobil SHC PM series
Our Mobil SHC? PM Series paper machine oils are designed to meet the challenging operating environments in today?s paper industry. These synthetic oils are formulated to protect bearings and gears in environments with high speeds (in excess of 2,000 m/min) and high steam temperatures (which can reach 200�C).
Mobil SHC PM Series paper machine oils are formulated with insights from our relationships with leading builders and are designed for exceptional performance in the latest paper-making equipment. They are recognized by major builders including SKF for their excellent protection of paper machine bearings and gear systems.
Developed to outperform mineral oils, these synthetic paper machine oils can:
- Increase machine oil life
- Improve circulation system cleanliness
- Reduce unnecessary downtime and premature component failure
Features and Benefits
The Mobil SHC PM Series oils represent a technological advance in paper machine lubrication. Their excellent performance capabilities in the areas of wear protection, enhanced oxidation stability, chemical stability, effective rust and corrosion protection, colour stability, and filterability not only prolong maintenance service intervals but can improve machine performance and increase production capacity. This can result in less required maintenance and longer equipment life.
