Castrol Magna SW D 220


Castrol Magna SW D 220 Slideway Oil


Castrol Magna SW D (previously called Magnaglide D Range) is specially formulated for the lubrication of slideways on machine tools. These oils are fortified with selected oiliness, extreme pressure additives and a special material to impart tackiness and adhesiveness.

Magna SW D lubricants are noted for their usual ability to overcome the stick-slip motion ordinarily associated with slow-moving tool parts. They reduce machine tool carriage chatter and possess the necessary adhesive characteristics to prevent squeezing out of the lubricant.


Magna SW D can be used on all horizontal and vertical slideways where a high-quality demulsifying lubricant is required for slideway protection and to maximize coolant life; the outstanding frictional characteristics of the products prevent stick-slip, improving surface finish and tolerances of machined components and reducing rejection rates.

The Magna SW D range meets the exacting demands in the following applications; planers, grinders, horizontal boring machines, shapers, jig borers, and milling machines.

Magna SW D 32 can be used as a combined hydraulic and slideway oil.

The Magna SW D range meets the requirements of:
Cincinnati Lamb (Milacron) P-47, P-50 and P-53 (depending on viscosity grade)
DIN 51502 – CGLP
DIN 51524 Part II (July 2004) – including ISO 13357-1/-2 filtration test
Suitable for Müller Weingarten equipment as hydraulic oil


Castrol Magna SW D 220 Slideway Oil Lubricant Advantages:

  • Excellent demulsification and metalworking fluid compatibility help to prevent soluble oil emulsions on slideway surfaces and to keep the coolant in clean conditions
  • High load-carrying capacity prevents the wear of highly loaded slideways and prolongs the life of machine parts.
  • Exceptional frictional characteristics prevent stick-slip. This provides high tool slide working accuracy and repeatable machining so that high-quality surface finish and tolerances are maintained at low rejection rate levels.
  • Protects metals against staining and corrosion which keeps oil-wetted surfaces in good condition and avoids downtime and expensive slideway repair or replacement.
  • Very good filtration property keeps filters in the oil supply unblocked
