FAG Spindle Bearings Normal design FAG Spindle Bearings FAG spindle bearings are specially designed single row angular contact ball bearings from which they differ by their contact angle the tolerances and the cage design Spindle bearings are especial ly recommended for bearing arrangements requir ing highest guiding precision standards and top speed suitability The are very well proven bear ings for machine tool spindles their main field of application Spindle bearings B719 B70 B72 High speed spindle bearings HSS719 HSS70HS719 HS70 two sealsunsealed Ceramic hybrid spindle bearings HCS719 HCS70HC719 HC70HCB719 HCB70 two sealsunsealedHCB72 All spindle bearings are available with the contact angle 15 C or with the contact angle 25 E For many years FAG have supplied spindle bear ings of series B719 B70 and B72 with steel balls Balls of the same size but made of ceramic materi al are used for ceramic hybrid spindle bearings of series HCB719 HCB70 and HCB72 High speed spindle bearings of series HS719 and HS70 and the ceramic hybrid spindle bearings of series HC719 and HC70 have smaller balls of steel and ceramic material They are suitable for still higher speeds at lower friction less heat de velopment and lower lubricant stressing resulting in a long service life Particularly cost effective solutions are obtained with the sealed high speed bearings of series HSS719 and HSS70 as well as with ceramic hybrid spindle bearings of series HCS719 and HCS70 These bearings have non rubbing seals at both sides They are grease lubricated for life and are maintenance free Normal design Spindle bearings of normal design are suffixed C T P4S or E T P4S The suffix identifies the con tact angle of 15 C or 25 E a solid window type cage of textile laminated phenolic resin T and the tolerance class P4S 201FAGFAG200 FAG Spindle Bearings Bearing sets Sets with 2 bearings D DBDFDT O arrangementX arrangementTandem arrangement Sets with 3 bearings T TBTTFTTT Combined O

mounting in pairs in X O or tandem arrange ment or for group mounting in any arrangement Bearing pairs of universal design UL have a light preload before mounting in O and X arrange ment With tight fits the preload of the bearing pair is increased see FAG publ no AC 41 130 for the machining tolerances of the bearing seats When ordering please state the number of indi vidual bearings not the number of bearing pairs or bearing sets Tandem arrangementO arrangementX arrangement Bearing sets Universal bearings of the same grade same bores and same outside diameters are available also as sets The user can mount them in any arrange ment Sets with a light preload are identified by DUL 2 bearings duplex TUL 3 bearings triplex QUL 4 bearings quadruplex When ordering please state the number of

FAG supply complete bearing sets consisting of two three or four spindle bearings of varying arrangements the coding system is shown on page 203 The suffix for the preload is added without a point to the letter combination Example of order 1 HSS7012C T P4S DBL Two spindle bearings in O arrangement light pre load before mounting Sealed spindle bearings FAG supply high speed spindle bearings HSS70 and HSS719 as well as ceramic hybrid bearings HCS70 and HCS719 lubricated for life and with non rubbing RSD seals on both sides Grease type grease quantity and sealing are selected in such a way that the bearings run at low tempera tures even at the highest speeds for a long time The maintenance free bearings are interchange able with unsealed bearings of dimensional series 70 and 719 Due to the little expenditure re quired for mounting lubrication maintenance as well as the long service life sealed spindle bear ings are cost effective solutions Tolerances FAG spindle bearings high speed spindle bear ings and ceramic hybrid spindle bearings are only available with narrow tolerances P4S is the stan dard tolerance class In this tolerance class the di mensional and form accuracies correspond to ISO tolerance class P4 and the running precision of the bearings to tolerance class P2 The deviation from nominal dimension of bore and outside diameter of the spindle bearings are stamped on the faces of the inner and outer rings designation e g and on the packaging The values are stamped on the packaging in the order of bore diameter outside diameter Example of packaging

suitability Heat treatment Equivalent dynamic load Cages The standard cage of spindle bearings is an outer ring riding machined window type cage of textile laminated phenolic resin suffix T The cage is suitable for long term operation at temperatures up to 100 C Speed suitability The standard DIN 732 part 1 thermal reference speed is not applicable to these precision bear ings The attainable speeds listed for spindle bearings apply to elastically preloaded and lightly loaded single bearings The speeds for grease lubrication are maximum values which are reached for exam ple using the FAG rolling bearing grease Arcanol L74V The values for oil lubrication apply to throwaway lubrication for example oil air lubri cation The speed values can be increased with cooling lubrication Since a considerable amount of oil must be pumped through the bearing to carry away heat the resistance to rotation may in crease The high speeds of single bearings are not reached if spindle bearings are mounted in pairs or are preloaded to increase the rigidity of the arrange ment The table shows the reduction factors for rigidly arranged bearings subjected to light pre load Heat treatment FAG spindle bearings are heat treated in such a way that they can be used at operating tempera tures of up to 150 C Bearings with outside di ameters of more than 240 mm are dimensionally stable up to 200
