RENOLIN HighGear Synth is based on selected synthetic base oils (PAO). Synergistic additives guarantee the excellent anti-wear 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 technology of these synergistic-ally acting additive systems is also known as Plastic Deformation reaction mechanism (PD technology). Surface roughness is reduced by a considerable smoothing effect. RENOLIN HighGear Synth Series surpasses the requirements on CLP gear oils acc. to DIN 51517-3: CLP and ISO 12925-1:CKC, CKD, CKE. Service intervals can be extended.
