CASTROL MAGNA SW 32
CASTROL MAGNA SW 32 is a dedicated slideway oil for machine tools. It combines controlled friction, high film strength and load carrying capacity to prevent stick-slip and support precise, repeatable machining.
Magna SW products are blends of refined mineral oil and high-performance additives. They are designed for horizontal and vertical slideways and offer excellent demulsibility and compatibility with metalworking fluids.
Applications
- Lubrication of horizontal and vertical machine tool slideways
- Combined hydraulic and slideway oil for light-duty systems
- Lightly loaded slideways, e.g. small lathes
- Combined hydraulic/slideway systems such as reciprocating grinding machines
Advantages
- Outstanding friction characteristics reduce stick-slip and improve machining accuracy
- High load carrying capacity protects heavily loaded slideways and extends machine life
- Excellent demulsibility prevents wash-off and keeps emulsions clean
- Protects metal surfaces against staining, wear and corrosion
- Helps minimise downtime and costly repairs
User advice
- A demulsifying lubricant is recommended to protect slideways and maximise coolant service life.
- Typical viscosity grade: ISO VG 32.
FAQ – Frequently Asked Questions about Castrol Magna SW 32
What is Magna SW 32 used for?
Magna SW 32 is a low-viscosity slideway and hydraulic oil for lightly loaded slideways and combined hydraulic/slideway systems.
Why is stick-slip prevention important?
Controlled friction helps avoid jerky motion, improves positioning accuracy and supports consistent surface finishes.
Is Magna SW 32 compatible with metalworking fluids?
Yes. Its good demulsibility and MWF compatibility keep emulsions stable and clean.
Which machines is it suitable for?
Typical for small lathes, lightly loaded guideways and systems requiring ISO VG 32.
Does it provide corrosion protection?
Yes. It protects metal surfaces from staining and corrosion, extending component life.
