Shell Tonna S3 M 68

Shell Tonna S3 M 68 Main Applications

+ Machine tool slideways, tables and feed mechanisms

Shell Tonna S3 M 68 developed for use on a wide range of materials used for machine tool slideway surfaces, including cast iron and synthetic materials.

+ Machine tool hydraulic systems

Particularly recommended for machines which have a ·combined hydraulic and slideway lubrication system.

+ Machine tool gearboxes and spindles

Also suitable for gear and headstock lubrication. The lower viscosity grades are intended for horizontal slide lubrication (Shell Tonna S3 M 32 or 68). For vertical slides use Shell Tonna S3 M 220.
