SYNTHETIC
CALENDAR LUBRICANT
|
|
SF-450 are fully formulated synthetic
lubricant specially designed for use in highly
rated units. They have an extremely high viscosity
index, low pour points and high load carrying
capacities, and show exceptionally low coefficients
of friction. Additives are incorporated to
reinforce the stability of oils.Their resistance
to corrosion and their resistance to scuffing
under unfavourable operating conditions. This
oil are capable of extremely long service.
ADVANTAGES
SELCO SF-450 being POLYGLYCOL, and
not mineral oil based, exhibits inherently
superior properties particularly with respect
to outstanding thermal stability and lubrication
performance. This properties are particularly
useful in heavily loaded mechanisms operating
at elevated temperatures e.g. worm gears
and calendar bearings.
PROVEN BENEFITS
 |
Reduced frictional losses,
leading to lower sump temperatures and
higher gear efficiency |
|
Improved load-carrying
properties and reduced wear. |
|
Higher thermal stability,
minimal sludge and deposit formation |
|
Inherently
higher viscosity index plus low pour
point enable equipment of operate over
a wider range of service temperature. |
|
Reduced power
consumption arising from easier starting,
faster warm-up and lower coefficient
of friction. |
APPLICATIONS
SELCO SF-450 is suitable for heavy
duty automotive and industrial gear boxes
with sump temperatures upto 140 ° C. The
product performance allows for extended drain
intervals and even, in some cases, for operation
as a "fill for life" lubricant.
The specially developed polyglycol-additive
technology of the new SELCO Synthetic Industrial
Lubricants SF-450 allows thermal stable operation
at temperatures in excess of 200 ° C.
These products are therefore preferred for
the lubrication of gears and bearings operating
at elevated temperatures, e.g. in calendar
equipment.
