SYG-1500/HD-LI-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-HD 1500 Li-GREASE is resistant to ageing and protects reliably against corrosion.
Application
SYG-HD 1500 Li-GREASE was especially developed for large lowspeed 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 heavy-duty grease with a high base oil viscosity and excellent anti-wear properties, such as grease like SYG-HD 1500 Li-GREASE. This grease is also suitable for the lubrication of pivoting bearings and plain bearings
Application notes
The ambient temperature should be ≥ 15 °C when SYG-HD 1500 Li-GREASE is applied with an automatic greasing pump
