Industrial ball bearings

Mobil SHC™ PM Series

Mobil SHC™ PM Series circulation oils provide a balanced performance for maximum reliability and productivity.

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
