WebDe meeste hydraulische oliën hebben een viscositeit van ISO VG 15 tot en met ISO VG 68. Dit is de viscositeit (dikte) bij 40 graden Celsius. De echte dikte van de hydraulische olie kan hier -10% en +10% van afwijken. In de (technische) handleiding van de machine of op een type plaatje staat vaak vermeld welke viscositeit in de machine moet. WebOils can be separated into multigrade oils and monograde oils. Multigrade oils must fulfill two viscosity specifications, their viscosity grade consists of two numbers, e.g. 10W-40: …
