TRUEGARD Spindle Oil 15 - 55 Gallon Drum

The '15' refers to the ISO viscosity grade of the oil. TRUEGARD Spindle Oils are available in multiple grades - including 4, 6, 10, and 15 - where lower numbers indicate lighter, thinner oils suited for very high-speed spindles and higher numbers suit slightly lower-speed or higher-load applications. Always consult your machine tool manufacturer's lubrication specification to confirm the correct ISO grade before selecting.

This oil is specifically formulated for the lubrication of high-speed machine tool spindles. Its light-bodied, light-colored composition is engineered to meet the demands of precision spindle bearings and chucks found on machine tools such as lathes, machining centers, and grinders.

Demulsibility is the oil's ability to shed water or water-based cutting fluids rather than forming a stable emulsion. In machine tool applications, this is critical because coolant contamination is common; an oil with good demulsibility separates cleanly from any water ingress, preventing sludge buildup and reducing the risk of spindles and chucks seizing shut.

TRUEGARD Spindle Oil 15 is compounded with additives that deliver excellent resistance to both wear and corrosion, helping protect the precision metal surfaces of high-speed spindle bearings and internal components from degradation during continuous operation.

Yes - the TRUEGARD Spindle Oil series includes grades 4, 6, 10, and 15, all sharing the same light-bodied, wear- and corrosion-resistant formulation. If your machine tool specification calls for a lighter grade, such as ISO 4 or ISO 6, those are available within the same product line.
