[0021] Another aspect that is equally important is that false-brinering or fretting can occur between the rolling elements of the bearing and the raceway before mounting in the application. The anti-fretting RP solution described herein can also reduce the risk of this type of wear occurring, for example, during transport and storage. Prevention of fretting wear by additives in the RP solution described herein is used to collectively reduce fretting wear in metal parts other than bearings, as well as in other situations than race rings it can. The transportation of metal parts often requires some form of fretting wear protection. A lubricant such as grease or a physical protective material such as plastic or cardboard. The fretting wear protection with the anti-fretting RP solution described herein can be quite sufficient to be used alone in place of these other forms of fretting wear protection at low cost.
