ABCDEFGHIJKLMOutline of Bearing SelectionOuline f BearinSelectionIKO Bearings are available in many types and sizes. To obtain satisfactory bearing performance in machines and equipment, it is essential to select the most suitable bearing by carefully studying the requirements for the application.Although there is no particular procedure or rule for bearing selection, an example of a commonly adopted procedure is shown in the figure below.IKO Berings are iablinmany types nd sies Toobttisactory bearing foance in machines and equipent, i iesentiatelect h ostsuiablebearingy carefullstudyin te equirementsfrt application.ltoug tereis no articua proedure or ulfrbearinglection, an exaple ofa ommny adoptd procedure isoin the igure below.An example of procedure for bearing selectionAn example of proedur for eaing selection123456789Confirmation of requirements and operating conditionsonfirmation of requirents and operating conditions1● Identify the machine and place where the bearing is to be used.● Confirm such as performance, and also confirm environment conditions.●Identy thmahn a acewhre he eaiis to be used.● Confirm the for bearings pfrma, and also confirm environent conditions.reuir aring th tng conditions and special euied bearing for bearings uch a theopetng conditin nd special equirements equiems the Selection of bearing typelection of bearing type2● Select the bearing type suitable for the operating conditions by considering load direction and magni- tude, rigidity, friction, allowable rotational speed, bearing space, etc.● Select the arng type stable for t operating contons by cnsiengoadictonnd magni- de, rgidiy, friction, alwe rotal speed, bearing A5space, etc.See ageSee pageA5Selection of bearing dimensionslection of bearingmensions3● Select the bearing dimensions by calculating bearing ● Select the baring dimeni calculating eain load, life, static safety factor, etc.load, life, stati styfactor, cSee pageSee pageA17A17Selection of accuracy class, etc.lection of cra class, etc.4● Select equipment.● Select equipment.th ccracy as required by thcuray as required by he achin or te machine or See pageSee pageA30A30Selection of radial clearance and fitlection of adial clearae and fit5the ● Select temperature, and outer rings, etc.●Select rdilrotational speed, meratre andouer rings, etc.radial clearnche clearance consiing inclination of considering fitthe inner icinaon of ratal sped he the fit, inner See pagethe See pageA37A37Determination of bearing dimensions, accuracy, radial clearance and fitDetermination of bearingmsons auray, adalclearne and fit6Selection of lubrication and dust-proof methodslection of lubrication and dust-roof methods7Design of surrounding partDsign of srounding part8● Select oil or grease lubrication.● Select oilor ges lbriati● After selection of lubricant, in case of oil lubrication, ● After seletionof licn n cof o lubrication, select the oil application method.select the oi aplctio thd.● Select the sealing method according to the lubricant.● Select the sealnetod accrdig ot lbricnA49Seepage● Design the surrounding part based on how to mount or dismount and based on mounting dimensions.● Desigte surrnng patbased on how to mount or smunt and based onmounidimensions.See pageSee pageA49See pageA57A57Determination of final specifications of the bearing and the surrounding partDetermination offinal scifation of the bearing an the srounding part9A16
