TRUEGARD Spindle Oil 4 - 55 Gallon Drum

It is specifically manufactured for high-speed machine tool spindles and is also classified as a Machine Tool Slideways Oil, making it suitable for precision spindle and slideway lubrication in machining environments. Always verify against your equipment manufacturer's lubrication specifications.

The number refers to the viscosity grade within the TRUEGARD Spindle Oil series, which also includes grades 6, 10, and 15. Grade 4 is the lightest in the series and is intended for the highest-speed spindle applications. Consult your machine manufacturer's manual to confirm which viscosity grade is required for your equipment.

Demulsibility is an oil's ability to separate cleanly from water rather than forming an emulsion. For spindle applications, strong demulsibility means water contamination from coolants or condensation is shed rather than retained in the lubricant, which helps prevent spindles and chucks from seizing shut.

A light-bodied, low-viscosity formulation is well suited to high-speed spindle bearings because it flows readily at elevated rotational speeds, maintaining consistent lubrication coverage where a heavier oil could cause drag or inadequate film distribution. This characteristic is central to why the product is engineered specifically for high-speed machine tool spindles.

The product is categorized by Truegard as a Machine Tool Slideways Oil, suggesting applicability to both spindles and slideways. However, given that the product name specifically references spindle use, confirm with your equipment manufacturer or Truegard's technical data whether Grade 4 meets the viscosity requirements for your specific slideway application.

An oil compounded for excellent wear and corrosion resistance helps protect precision spindle components from metal-to-metal contact degradation and oxidation-related damage, which can extend the service life of spindle bearings and reduce unplanned downtime and maintenance costs over time.
