RENOLIN ZAF B
Zinc- and Ash-Free HM Hydraulic Oils and CKC Lubricating Oils
Zinc- and Ash-Free HM Hydraulic Oils and CKC Lubricating Oils
Zinc-free hydraulic oils have steadily gained popularity over the last few years.
In many cases, the use of a zinc-free hydraulic oil is a must, especially in machine tools where hydraulic fluids can contaminate metalworking fluids. RENOLIN ZAF B hydraulic oils are zinc- and ash-free HM hydraulic oils complying with ISO 6743-4.
The most important features of RENOLIN ZAF B hydraulic oils are:
-
Good oxidation stability and good resistance to ageing
-
Powerful EP properties and very good wear protection
-
Excellent corrosion protection
-
Rapid air release and low foaming
-
Good demulsification characteristics
-
Good compatibility with sealing materials
Application:
RENOLIN ZAF B products are high-grade HM hydraulic oils according to ISO 6743-4 which can be used in all hydraulic systems but also as CKC lubricating oils according to ISO 6743-6 in gearboxes, bearings and circulating systems. RENOLIN ZAF B products are recommended for use in machine tools where contact between hydraulic oils and metalworking fluids can take place.
