Abstract: The aim of research – the exploring of tribological properties of rape and sunflower oil based greases, produced with different thickeners and conditions of production technology. Friction measurements show that after initial variation the friction torque of sunflower and rapeseed oil based greases stabilises at the level which is lower than liquid bio-oils at the same conditions. Wear results show highest wear resistance of rapeseed oil based grease with lithium stearate comparing to other bio-based greases. Sunflower oil based grease is more efficient when it is prepared at lower mixing temperature. Tribological investigations show that different factors should be taken into account at the preparation and investigation of bio-based greases. For some biodegradable greases the influence of its preparation (thermal conditions) are very important (sunflower oil based grease) for other greases (rapeseed oil based grease) the kind of thickener is determinant for tribological efficiency
