Spiral groove bearing

Spiral groove thrust bearings are self-acting bearings used to reduce friction and wear without the use of pressurized lubricants. They have this ability due to special patterns of grooves. Spiral groove bearings are self-acting because their own rotation builds up the pressure needed to separate the bearing surfaces. For this reason, they are also 'contact-less' bearings.
