The formulation shows also excellent wear protection of roller bearing in the roller bearing wear test. The relevant test in the FAG/FE8roller bearing wear test at 7.5 rpm/80 °C at an axial load of 80 KN is passed with extremely low wear rates.

In the summary all relevant performance criteria of industrial gear oils are passed and surpassed. 

The RENOLIN ZAF D HT products surpass the requirements for hydraulic fluids (according to DIN 51524, part 2) and industrial gear oils (DIN 51517, part 3).

The products are universally applicable, the formulation is robust. The products have high oxidation and stability, also under the influence and in the presence of humidity and water. The development of the RENOLIN ZAF D HT Series is also focussed on excellent yellow metal compatibility. In different laboratory tests bronze material, copper/zinccontaining alloys are tested at high temperature over a long test period in dry and wet conditions. The property of the oil, the corrosiveness of the metal surface is determined. After the test, the content of dissolved metals in the oil phase is measured.

The RENOLIN ZAF D HT products show excellent corrosion protection results, no copper, zinc metals are dissolved in the oil phase, also under severe test conditions.

The RENOLIN ZAF D HT products guarantee, therefore, excellent corrosion protection of yellow metal materials which are used in pumps, hydraulic motors, hydraulic pistons and bearings.

The oxidation stability, also in the presence of catalytically acting copper and iron and yellow metal materials, is high. The test shows at high temperatures the robustness of the formulations. The products are stable under severe conditions, sludge is reduced, carbon residues on metal surfaces can be reduced.


The products of the RENOLIN ZAF D HT Series are high-performance robust hydraulic oils as well as lubricating oils. The products can also be used as industrial gear oils. RENOLIN ZAF D HT products are universal oils and can be used for various applications as hydraulic oils (HLP-D) as well as industrial gear oils (CLP, CLP-D). The RENOLIN ZAF-D HT Series is recommended as deterging hydraulic, gear and lubricating oil in hydraulic equipments, in presses and tool machines. RENOLIN ZAF D HT products can be used in stationary and mobile hydraulic systems.
