Types of grease and grease selection - Mobil

18/2/2016· Let me try to demystify grease a bit. Different types of greases are typically formulated with three grease components: base oil, thickener and additives. The base oil lubries, reducing friction between moving surfaces; this is exactly the same role that the base oil plays in a lubricant oil. The thickener acts like a sponge; its job is to

How Does a Slew Ring Work? | igus blog

15/10/2021· Because slewing rings based on ball bearings have very small contact points (ball bearings touching the inner and outer ring surfaces), they are able to move with very low friction. Slewing rings that are based on plastic liners to facilitate movement (with a larger inner ring surface to better handle heavier loads) work better for flat, horizontal appliions .
