Based on which of these wear mechanisms is in an active state, the wear rate experienced by a specific material may significantly increase or decrease depending on its unique material properties. ??? ????????? ??? ???? ??? ?????? ???? ?? ??????????? ???? ??? ?????????????? ???? ?????????, ??????????????????????????, ???????????? ??????????

Although many people believe that the hardness of a material is the key factor determining its wear resistance, it is also heavily influenced by several other complex factors. These may include the lubricity, surface roughness, and friction coefficient of the material, depending on the specific situation.

Many bearings require clean oil or other suitable lubricants to form a thin film between the bearing and other parts. ??? ????“, ????? ??? ???? ???? ?? ?? ????? ????. But unless the bearings are made of "self-lubricating" materials, using them without proper lubricants can quickly cause equipment to get stuck and wear out the bearings.
