Super Precision Angular Contact Bearingsfor Machine ToolsNSK offers “universal” bearings, SU or DU, that can be used to create various angularcontact ball bearing arrangements. A universal angular contact ball bearing is one withthe same offset ground on both front and back faces. Reference Fig. 1, (f b). This offsetrelates directly to the bearing’s stringent preload control and enables universal bearingsto be combined or form back to back (DB, DBD, DBB) or face to face (DF, DFD, DFF) sets.Features› S tate-of-the art preload control› High point of eccentricity marked on inner and outer rings › B earing and box marked with actual bore, OD, andwidth deviation from nominal (units are microns µm),see figures 3a, 3b and 3c›H igh performance phenolic cageFig. 1fHigh Point of Radial RunoutThe high point of radial runout is indicated by a small circle orburnished spot on the inner ring face (Fig. 2a) and by a ‘V’ lineon the outside diameter of the outer ring (Fig. 2b). The bearingscan then be mounted with these marks axially aligned with eachother and opposed to the shaft or housing eccentricities in order tominimise assembled runout.Fig. 2aαFig. 2bf: Offset of Front Faceb: Offset of Rear FacebFig. 3aUniversal Bearingf bFig. 3bNominal dia.Total OD toleranceNominal boreTotal bore toleranceFig. 3c100BER19STYNSUELP3RNB5X5DD424804904Made in EnglandD -5 f -1d -5 b -1-45CD:d:C:f:b:14N-5-5-45-1-1 Outer Ring ODInner Ring BoreBearing WidthFront Face PreloadRear Face Preload
NSK Verify AppBackground InformationNSK has launched the NSK Verify mobile application primarily for machine toolprecision bearings to support efficient operation and IT-based plantmanagement. This free app helps simplify bearing selection and improve theuse history and traceability of the product. NSK Verify also helps protectcustomers from counterfeit products with several features able to verify productauthenticity.Features and BenefitsSmartphones with the app can scan the 2D barcode printed on each NSK bearing box for instant access toinformation such as:› Anti-Counterfeit check authenticity of product› check number of access by product ID› individual identification number and - in addition for general bearings - the bearing number (20 Digits)For machine tool precision bearings› bearing inspection record*› dimensional tolerances› running accuracy› grease type*For precision bearing of OD above 210 mm, there will be NO inspection certificate report generated in NSK Verify.Compatible with iOS and Android devices, the app is available in English, Japanese and Chinese and upgradedversions.iOS: Version 1.2.0 1.2.1 and Android: Version 2.1.0 2.1.1NSK VerifyNSK websiteApp for iOSApp forAndroidSUPER PRECISION BEARINGS - MACHINE TOOL APPLICATIONS 15

Fitting on Shaft and HousingIt is of utmost importance that shafts and housings areaccurately and precisely mated in order to take full advantageof the precision bearings’ capabilities, which include rotationalaccuracy, high speed performance, and low heat generation.When the inner ring or outer ring is mounted onto a shaftor into a housing with some interference, the shape of shaftor housing (out of roundness) is transferred to the bearingraceway surfaces andBearing type 3Machine toolspindle bearingFits 1 on shaftsAngular contact thrustball bearing forball screw supportBearing type 3Angular contact ballbearing (fixed side)Angular contact ballbearing (free side)Fits 1 in housingCylindrical rollerbearingAngular contact thrustball bearing forball screw support1.Shaft outer diameter (mm)affects running accuracy. When different arrangements ofangular contact ball bearings are used, cylindricity affectsthe distribution of preload for each bearing. Therefore, themating parts should be as accurate as possible. Inaccuratemating of parts can cause the formation of peaks or ridgesalong the shaft of a precision lathe, which can affect thequality of finished work.Tolerance of shaft 2 outer diameter (mm)Target interference 2,4 mum0.002 T1850-0.004000.0025 T5080-0.005000.003 T80120-0.0030.00300.004 T120180-0.0040.00400.004 T180250-0.0050.00500.005 ��5080-0.0130––80120-0.0150––Housing bore diameter (mm)Tolerance of housing 2 bore diameter (mm)Target clearance 2,4 20.0020.002 L0.006 L5080-0.00250.00250.002 L0.006 L80120-0.0030.0030.003 L0.008 L120180-0.0040.0040.003 L0.008 L180250-0.0050.0050.005 L0.010 L185000.0040.006 L0.011 L508000.0050.006 L0.011 L8012000.0060.009 L0.015 L12018000.0080.009 L0.015 L18025000.0100.015 L0.022 L1850-0.00600.002 L0.002 T5080-0.00700.002 L0.002 T80120-0.00800.002 L0.002 T120180-0.00900.002 L0.002 T180250-0.01100.002 L0.002 08000.019––8012000.022––T he fitting data above provides general recommendations for machine tool spindles operating under normal conditions and for dmn values of less than 800,000.
