What are Hydraulic System Oils?

   From our daily life to industrial applications, we encounter hydraulic systems almost everywhere. Hydraulic systems are used almost everywhere, from toys in the amusement park to garbage trucks, from automobiles to construction machines, from iron and steel enterprises to plastic injection machines.
Hydraulic oils are the biggest and decisive factor causing malfunctions in hydraulic systems. Even in a hydraulic system made of the best materials in the world, failures will occur in a very short time if a suitable and high quality hydraulic oil is not used.

What are Hydraulic System Oils?

   There are hydraulic oils number 32, number 46, number 68, number 100, which are named with their viscosity values ​​at 40°C. HH and HL class old technology hydraulics are no longer preferred by world manufacturers, HM and HV class hydraulic system oils are widely used all over the world.

It is seen that HV class hydraulics are developed in addition to HM class hydraulics, and show resistance to viscosity index and temperature change.

What does viscosity index mean?

   The viscosity index is an indicator of the performance of the additive packages (anti-foaming additive package, anti-wear additive package, anti-rust additive package, adhesion and adhesion enhancing additive package, etc.) added to improve the performance of the oil.
