What prevents metal particles from adhering to bearings?

Metal particles are prevented from adhering to bearings primarily through the use of lubricants that create a protective film between the metal surfaces. This film reduces friction and minimizes direct contact, thus preventing wear and the potential for particles to bond. Additionally, proper maintenance and the use of filtration systems help remove contaminants, further reducing the likelihood of particle adhesion. The material properties of the bearings themselves also play a role, as certain coatings can enhance resistance to particle attachment.
