福斯润滑油 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. | RENOLIN ZAF |
