What Are PAG Gear Oils?
PAG, or polyalkylene glycol, is a type of synthetic base fluid used to formulate lubricants for particular industrial applications. PAG gear oils can provide good thermal and oxidation stability, helping the lubricant maintain its properties when exposed to demanding temperatures and extended periods of operation.
Where Are PAG Gear Oils Used?
PAG gear oils can be used in industrial gearboxes and other specialised gear systems where this lubricant technology is specified. Applications can include worm gears and heavily loaded or high-temperature gear systems, although suitability will depend on the individual equipment and lubricant specification.
Benefits of PAG Oils in Gear Systems
One characteristic of PAG lubricants is their ability to provide low friction in suitable gear applications. This can be particularly relevant in gear systems with a high degree of sliding contact, such as certain worm gears. PAG formulations can also provide resistance to oxidation and deposit formation under demanding operating conditions.
PAG Oil Compatibility
Compatibility is particularly important when working with PAG lubricants. PAG oils may not be compatible with conventional mineral oils or some other synthetic lubricants, and compatibility with seals, paints and other materials should also be considered.
If changing from another lubricant type to a PAG gear oil, the manufacturer's recommended changeover or flushing procedure should be followed. Flushing Oils may be relevant where an appropriate system flushing process is specified.
Related Gear Oils and Lubricants
PAG gear oils are intended for specialist applications and shouldn't automatically be substituted for other gear lubricants. Industrial Gear Oils cover a broader range of industrial gearbox applications, while Automotive Gear Oils and Hypoid Gear Oils are available for suitable vehicle and drivetrain systems.
Other parts of industrial machinery may require Bearing & Circulating Oils, Hydraulic Oils or Greases, depending on the component and manufacturer's lubrication requirements.
Finding the Right PAG Gear Oil
Before selecting a PAG gear oil, check the equipment manufacturer's recommendations for base oil type, viscosity grade and performance specification. If changing from another type of lubricant, compatibility and the correct changeover procedure should also be confirmed.
