Fuchs Renolin High Gear 320


Fuchs Renolin High Gear 320 Is a special gear oils with state-of-the-art additive technology.

Fuchs Renolin High Gear 320 is an Industrial gear oils of newest additive technology – Plastic Deformation (PD) technology.




FUCHS RENOLIN HighGear is a highlight of the latest FUCHS R&D activities. RENOLIN HighGear is based on selected paraffinic mineral base oils. Synergistic additives guarantee the excellent antiwear and extreme-pressure performance of these new high-tech industrial gear oils. Even under extreme load conditions, extreme mixed-friction and boundary-friction conditions, at high pressures, at high specific loads and at low relative velocities, on rough surfaces and on pre-damaged surfaces in gears, the newly developed additive technology prevents wear, scuffing and scoring, as well as damages. The synergistically acting additives are based on special sulfur components, selected surface-active phosphorus components, special zincdialkyldithiophosphates and mineral oil-soluble liquid molybdenum components which can form high-performance tribo protection layers in the contact zone of gear wheel and pinion, in roller bearings and in machine elements under high load.

The high-performance tribo protection layers prevent wear at high and low temperatures and under extreme working conditions.
The technology of these synergistically acting additive systems is also known as Plastic Deformation (PD) reaction mechanism. Surface roughness is reduced by a considerable smoothing effect.

The excellent resistance to scuffing and scoring, a high failure load stage in the FZG test, an excellent FE8 roller bearing wear protection and an extremely high resistance to pitting (which can not be reached when using standard industrial gear oils) demonstrate the excellent technical performance of the fully formulated RENOLIN HighGear CLP oils. The pitting test was passed with excellent results, which indicates that the formulation will also offer an excellent protection against micro-pitting.

Advantages / Benefits

• Extremely low friction coefficient at high loads
• High resistance to scuffing and scoring
• Extremely high pitting resistance
• High micropitting load capacity
• Excellent FE8 roller bearing wear protection
• Excellent corrosion protection (steel and copper materials)
• Miscible with conventional, mineral oilbased industrial gear oils
• High resistance to ageing, high additive reserve
• Low foaming, good air release
• High thermal stability, no sludge formation
• PD technology, Plastic Deformation, smoothing effect



RENOLIN HighGear oils offer an improved thermal and oxidation stability. Under extreme thermal conditions, the formation of sludge under the influence of air (and oxygen) can be avoided. Even
when exposed to extreme conditions, RENOLIN HighGear oils remain stable during a long period of time. The synergistic additive systems remain dissolved in the oil during the long lifetime even at
high temperatures. The new additive technology also offers excellent corrosion protection (steel and yellow metal materials ) which was tested under extreme test conditions.

RENOLIN HighGear products are based on the latest additive technology. Field trials in heavy gear units in the coal / mining industry under extreme working conditions (high temperatures, extreme mixed-friction conditions, pre-damaged tooth
surfaces) show that the damage mechanism in the machine elements could be stopped, the surfaces of the tooth flanks could be smoothed and the roughness could be reduced due to the plastic
deformation properties of the chemically reacting additives. This high performance could also be demonstrated in spindle systems of forming presses which are also working at high temperatures, under
extreme mixed-friction conditions and at low velocities. The field test results are in line with the excellent results in mechanical-dynamic tests which were carried out in the FUCHS mechanical-dynamic test field.

RENOLIN HighGear oils can be used in all types of new gears under extreme working conditions to reduce wear, friction and noise. They are also recommended for pre-damaged gear sets, spindles and machine elements to increase the lifetime of the components.
RENOLIN HighGear is approved by Siemens AG, Flender gears.
