Usually grease of some kind is used to reduce friction. But there are also different ways - changing materials of cooperating parts (different coefficient), switching to rolling friction (like in rolling bearings) or using air/hydraulic fluid instead of mechanical contact (this method is used in aerostatic and hydrostatic slideways).
