FAQ – Castrol Magna SW B 100
Where is Magna SW B 100 used?
In heavily loaded slideways requiring stable lubrication and precise feed movement.
Why is demulsibility important?
It separates water-miscible coolants quickly and prevents deposits on slideways.
Does it prevent stick-slip?
Yes, due to its strong adhesive film.
Can it be mixed with other oils?
Mixing with zinc-containing oils should be avoided.
Is it suitable for metal/plastic slide pairs?
Yes, it is approved for both metal and combined pairs.
