Specifications and Approvals

Shell Tonna S2 M oils meet the following specifications:

• ISO 19378 / ISO 6743-13 GA and GB
• DIN CGLP
• Cincinnati Machine P-50 (ISO 220), P-47 (ISO 68), P-53 (ISO 32)

Applications

• Machine tool slideways, tables and feed mechanisms

Developed for use on a wide range of materials used for machine tool slideway surfaces, including cast iron and synthetic materials.

Shell Tonna S2 M oils can be used also in the hydraulic and gearboxes system although in such applications Shell Tonna S3 M oils are generally preferable.

The lower viscosity grades are intended for horizontal slide lubrication (Shell Tonna S2 M 32 or 68). For vertical slides use Shell Tonna S2 M 220.
