Category:

Shell Tonna S2 M 68

( Previously named: Shell Tonna T )

Premium-grade mineral oil for machine tool slideways and feed mechanisms

  • Enhanced stick-slip control for improved surface finish and dimensional accuracy

  • Excellent separation from water-miscible cutting fluids to extend coolant life

  • Strong adhesion to slideway surfaces to reduce wash-off and oil consumption

  • Anti-wear protection for slideways, gears, bearings, and hydraulic components

  • Superior corrosion prevention in the presence of water-based cutting fluids

  • Compatible with a wide range of materials including cast iron and synthetics

  • Suitable for use in horizontal slide lubrication (ISO VG 32 or 68)

Global Product Code: 001D7771



Application:

Shell Tonna S2 M 68 is a dedicated lubricant for machine tool slideways, tables, and feed mechanisms. Designed for precision engineering environments, it is especially recommended where high exposure to soluble cutting fluids exists. Formerly known as Shell Tonna T.

Performance Features & Benefits:

  • Excellent Coolant Separation: Quickly separates from water-miscible cutting fluids to help extend coolant life and improve machining performance.
  • Good Slideway Adhesion: Clings to surfaces and resists wash-off, promoting uniform lubrication and reducing consumption.
  • Superior Frictional Properties: Eliminates stick-slip, enabling accurate positioning and high surface finish quality.
  • Reliable Wear Protection: Protects slideways, gears, and bearings from wear under load.
  • Corrosion Resistance: Prevents rust and corrosion even in water-rich environments.

Main Application Areas:

  • Horizontal slide lubrication systems (ISO VG 68)
  • Machine tools operating with water-based cutting fluids
  • Hydraulic and gear systems (Shell Tonna S3 M recommended for these uses)

Specifications & Approvals:

  • Fives Cincinnati P-47 (ISO 68)
  • ISO 19378 / ISO 6743-13 GA and GB
  • DIN CGLP (DIN 51502)
  • GB 11118.1 L-HG

Environmental & Safety Information:

  • Minimize skin contact with used oil and use appropriate personal protection.
  • Dispose of used oil responsibly through an authorized collection point.
  • Safety Data Sheet (SDS) available via inquiry
