CASTROL MAGNA SW 68
CASTROL MAGNA SW 68 is a medium-viscosity slideway oil for machine tools. Its formulation delivers controlled friction, high film strength and load capacity to reliably prevent stick-slip.
Magna SW 68 is suitable for most machine tool lubrication systems specifying ISO VG 68. With excellent demulsibility, the oil stays on the slideways, helping keep emulsions clean and stable.
Applications
- Lubrication of horizontal and vertical machine tool slideways
- Systems requiring ISO VG 68 slideway oil
- General slideway lubrication in modern machine tools
Advantages
- Reduces stick-slip and improves machining accuracy
- High load carrying capacity protects heavily loaded guideways
- Demulsifying and MWF compatible – keeps emulsions clean
- Reliable protection against wear and corrosion
- Helps minimise downtime and maintenance costs
User advice
- A demulsifying lubricant is recommended to protect slideways and maximise coolant service life.
- Typical viscosity grade: ISO VG 68.
FAQ – Frequently Asked Questions about Castrol Magna SW 68
What is Magna SW 68 used for?
