Fluid Grease for Gears, synthetic

OKS 428 is a synthetic fluid grease for gears.

Areas of application

Lubrication of heavy loaded toothed gears and worm gears exposed to outdoor conditions and/or low temperatures, as well as tilted or vertical shafts, especially with gear designs which are not oil-tight
Lubrication of friction bearings with minimal bearing clearance or high circumferential speeds

Advantages and benefits

Long-term lubrication due to excellent resistance to oxidation and ageing
Wear reduction at maximum loading
Prevents leakage with angled or vertical shafts due to good adhesion on metallic surfaces
Flowing structure prevents grooving in gear units with continuous coverage of surfaces
