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 synergistically 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.
