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.
