SYG-20/TORQ LI-1500
HEAVY DUTY GREASE
Product Description
This heavy-duty grease consists of a highly viscous mineral hydrocarbon oil (ISO VG 1500), special lithium soap and particularly effective EP/AW additives. It also contains solid lubricants (MoS2 and graphite) to ensure reliable operation under starved lubrication conditions. SYG-20/TORQ LI-1500 is resistant to ageing and protects reliably against corrosion.
Application
SYG-20/TORQ
LI-1500 was especially developed for large low speed rolling bearings subject
to high loads. It is typically applied to lubricate the bearings of rollers
(spherical roller bearings) in roller presses, bowl mill and rotary crushers in
the base material industry. The operating conditions of the roller bearings.
i.e
· low
speed, n = 10-30 rpm
·
High load, P/C = 0.25 – 0.50
· Bearing
temperature approx. 50-70 °C
· Shock
and vibration loads require a heavy-duty grease with a high base oil viscosity
and excellent antiwear properties, such as a grease like SYG-20/TORQ LI-1500.
This grease is also suitable for the lubrication of pivoting bearings and plain
bearings
Application notes
The ambient temperature should be ≥ 15 °C when it is applied with an automatic greasing pump
