This Limiting Speed Calculator will use the bearing and application information you input to approximate a speed the bearing may rotate at while achieving some reasonable life in your application. The way your provided information is used to determine this Limiting Speed is the result of more than 20 years experience and engineering data. Other variables of each application that have not been taken into account in these calculations will affect the actual Limiting Speed and Service Life results.

Limiting speed derived from values listed in this formula are intended for general guidance only and should not be used as reliable information in specific applications.

Every application has a variety of unknowns which may dramatically affect the limiting speed and service life of bearings. No guarantee of limiting speed or service life should be assumed based on this formula.

Each application should be tested to determine actual limiting speed and service life of the bearing.
