SYNTHETIC PAG HEAT-TRANSFER CALENDER LUBE
XL-0866 series of fluids are specially compounded synthetic derivatives that offer performance
characteristics not available in petroleum-based products. Under demanding
conditions, the XL-0866
series perform well where
other lubricants fail. They minimize wear and maintenance and limit
interruptions in output caused by reduced downtime.
XL-0866 is manufactured using water-soluble polyalkylene glycol base stocks, which are
known to provide outstanding EP characteristics. These pure PAG base stocks
combined with the addition of a high performance, food approved additive
package, these products are able to offer excellent thermal stability, high wear
reduction rates, extremely high micropitting resistance and load carrying
ability as well as excellent corrosion protection.
The XL-0866 Series features:
• High Viscosity Indexes
• Chemical and Thermal Stability
• Compatibility with Metallic and Elastomer Components
• Good Water Solubility
• Excellent Shear Resistance
XL-0866 Series typical
• Calender rolls
• Fill for life gearboxes
• Compressors – Both rotary screw and reciprocating
• Textile lubricants
• Chain and conveyor lubricants
• Kiln and oven lubricants
The inherent high viscosity indices provide useful viscosities at elevated
temperatures. At operating conditions between 150 to 200ºC, this means better
load-carrying properties of hydrodynamic fluid films in highly loaded bearings.
Even under thin film and boundary conditions found especially in slow moving
(heavily loaded) bearings, XL-0866 series
has demonstrated excellent load-bearing performance.
The XL-0866 Series protects against oxidative corrosion rendering them chemically
and thermally stable. Unlike
other organic materials that oxidize at elevated temperatures in the presence of
air, the by-products of oxidation inherent to the XL-0866 series
are generally soluble or volatile. Therefore, the tendency to form sludge,
varnishes, or carbonaceous residues are greatly reduced.
XL-0866 series are formulated with additives specifically designed to provide compatibility
with common metals such as iron, steel, brass, bronze, and aluminum. They are
also compatible with most natural and synthetic rubber compounds and gasket
materials. Therefore, the main consideration for elastomer and seal selection
will be the elevated temperatures to which they are exposed.
The XL-0866 Series of fluids are soluble
in water at ambient
temperatures. If they are spilled, they can be removed with water. If they
become contaminated with limited amounts of water in circulation, they will form
a homogeneous solution that will provide continuous lubrication to all vital
parts. The water will quickly evaporate at high temperatures.
The XL-0866 series is fully approved and listed as such by the following gearbox OEM’s:
|David Brown:||Type G Lubricant|
|Flender:||(SL 150 – SL1000) for use in Helical, Bevel Helical, Planetary and
Further details concerning these approvals can be provided on request.
When changing from a mineral oil or PAO based product to one of the XL-0866 series,
the following procedure should be followed:
The system should be run until the old oil is warm, then drain as fully as
possible, particular attention being paid to reservoirs, lines etc., where oil
may be trapped. The system should be cleaned of residual sludge.
Flush the system with the minimum quantity of XL-0866 by
operating under no load, and then drain the system whilst the fluid is warm.
Repeat if necessary.
Seals, etc., should be inspected and if deteriorated then replaced. Seals
previously exposed to other oils may shrink when exposed toXL-0866 series
fluids, therefore it may be advantageous to replace them. This is not mandatory,
as careful inspection of the system for leaks will often suffice. It is useful
to inspect the lubricant after one or two days in use to make sure that it is
free of extraneous materials. Contamination with significant quantities of other
lubricants can, in some cases, lead to sludging, foaming and other problems.
May be blended with powdered graphite
for extra boundary film protection.
