Toleranzen

Abgedichtete einreihige NKENKENKENKE

Schrägkugellager werden in Normaltoleranz(PN) gefertigt.

Detaillierte Werte der einzelnen Toleranzklassenentnehmen Sie bitte den Tabellen im NKENKENKENKE

Hauptkatalog, Abschnitt „Lagerdaten /Toleranzen“, ab Seite 64

Wärmebehandlung

Die Kugeln und Ringe der abgedichteteneinreihigen NKENKENKENKE Schrägkugellager werdenstandardmäßig für Betriebstemperaturen bis+150°C ( Wärmestabilisierungsklasse S0)massstabilisiert.

Es muss allerdings beachtet werden, dass diepermanente Betriebstemperatur von

abgedichteten Schrägkugellagern derStandardausführung durch die verwendetenDichtscheiben, die Polyamidkäfige sowie denverwendeten Schmierstoff limitiert wird unddaher 120°C nicht übersteigen sollte.

Weiters ist darauf zu achten, dass bei Dauer-Betriebstemperaturen über 70°C dieSchmierstoff – Gebrauchsdauer stark reduziertwird.

Weitere Informationen dazu entnehmen Sie bitte

dem NKENKENKENKE Hauptkatalog, Abschnitt„Schmierung von Wälzlagern“, ab Seite 162

Für Sonderanwendungen können auf Anfrageabgedichtete NKE Schrägkugellager auch ineiner speziellen Hochtemperaturausführunggeliefert werden.

Für Sonderausführungen ersuchen wir diejeweilige Verfügbarkeit anzufragen.

Tolerances

NKE Single Row Angular Contact BallBearings with seals or shields are produced,as standard, to normal tolerance class (PN)

Values for the individual tolerance classes arelisted in the tables, see NKE GeneralCatalogue, “Bearing data / Tolerances”, page260 onwards.

Thermal Stabilisation Class

The rings and balls of NKENKENKENKE Single RowAngular Contact Ball Bearings with seals orshields are thermal stabilised for operatingtemperatures up to +150°C (+302°F) asstandard, i.e. thermal stabilisation class S0.

However, it must be taken into considerationthat – for standard design single row angularcontact ball bearings with shields and seals,respectively, an actual constant operatingtemperature of +120°C (+248 °F) maximummust not be exceeded, due to the seal lipmaterial, the polyamide cage and thetemperature limits of the grease used.

It must also be considered that the actualservice life of the grease drops dramaticallywhen the actual operating temperature isconstantly above +70°C (+158 °F ).

For further specific information please refer tothe NKE General Catalogue, “Lubrication ofRolling Bearings”, page 359 onwards.

NKE also produces Single Row AngularContact Ball Bearings with seals or shields,respectively, in special High temperaturedesign to customer order.

Please check availability.

Bearing Life Calculation

NKE Single Row Angular Contact BallBearings with seals or shields, respectively,are based on Bearing series 72 BE and 73 BE.

Thus, the same procedures and formulas maybe used for estimating the bearing life ratings asdescribed for standard angular contact ballbearings when used as individual bearings, seepage 14.

Note:

When the actual operating temperature isconstantly above +70°C (+158 °F ), a check ofthe grease service life is recommended inaddition to an estimation of the bearing liferating.

For further specific information please referto the NKENKENKENKE General Catalogue, “Lubrication ofRolling Bearings”, page 359 onwards.

Achtung:

Zöllige Schrägkugellager der Standard-ausführung sind für einen paar- odersatzweisen Einbau NICHT geeignet !

Für andere Ausführungen ersuchen wir diejeweilige Verfügbarkeit anzufragen.

Schiefstellung

Einreihige Schrägkugellager sind zum Ausgleichvon Schiefstellungen nur sehr beschränktgeeignet.

Bei Einzellagern haben - unter normalenBetriebsverhältnissen - Schiefstellungen vonmaximal 2 Winkelminuten üblicherweise nochkeine negativen Auswirkungen.

Allerdings weisen Schrägkugellager, die unterSchiefstellungen laufen, erheblich höhereLaufgeräusche auf, es ist auch mit einerVerringerung der Gebrauchsdauer durch dieZusatzbelastungen zu rechnen.

Toleranzen

Für die Hauptabmessungen der einreihigenNKE - Schrägkugellager in Zollabmessungengelten standardmäßig Toleranzen gemäß BS292:Part2:1982.

Detaillierte Werte entnehmen Sie bitte derTabelle Toleranzen“, auf Seite 59.

Bearing Arrangements

NKE inch sized Single Row Angular ContactBall Bearings are produced as standard forbeing use as individual bearings.

NOTE:

Standard design Inch sized angularcontact ball bearings are NOT suitable foruse as bearing pairs or sets!

For other design variants, please consultNKE.

Misalignment

Single row angular contact ball bearings have avery limited ability to accommodatemisalignments.Therefore any operating misalignments applied

to this bearing type create additional forcessubsequently reducing their service life and,additionally, generates higher running noiselevels.

Where individual single row angular contactbearings are used; up to 2 angular minutesmisalignment from the centre position does notnormally affect the bearings negatively.

Tolerances

NKE inch sized single row angular contactball bearings have tolerances for theirboundary dimensions according to BS292:Part2:1982 as standard.

Detailed values for single bearing toleranceclasses are listed in the tables on page 59.

Mindestbelastung:Bei Schrägkugellagern sollte für einezufriedenstellende Funktion unter normalenBetriebsbedingungen eine Mindestbelastungvon etwa 1 bis 2 % der dynamischen Tragzahl

Cr gegeben sein.

Äquivalente dynamische Lagerbelastungfür Schrägkugellager in Zollabmessungen

Bei als Einzellager eingesetzten NKESchrägkugellagern in Zollabmessungen mit

einem Druckwinkel von αααα = 20°gilt:

Achtung:

Durch den Druckwinkel verursacht beiSchrägkugellagern jede äußere Belastung eineinnere Axialkraft.Zur Berechnung der resultierenden Axialkraft

Fa sind daher auch die Hinweise aus Tabelle3 (siehe Seite 17) zu beachten.

Für die NKE Schrägkugellager inZollabmessungen mit einem Druckwinkel von

αααα = 20° ist allerdings der Faktor 1,14 durch0,57 zu ersetzen.

Der Abstand „a“, der zur Berechnung derwirksamen Lagerabstände erforderlich ist, kannwie folgt berechnet werden:

Minimum load:Angular contact ball bearings should alwaysoperate with a minimum bearing load ofapproximately 1 to 2 per cent of the dynamic

load rating Cr.

Equivalent dynamic bearing load forinch sized angular contact ball bearings

For individual use NKE inch sized angularcontact ball bearings having a contact angle αααα =20 °the, following formula must be used:

Note:

In the case of angular contact ball bearings,each external radial load applied generates aninternal thrust force.For the calculation of the resulting axial force

Fa the information provided in table 3, page17, should be considered.

For NKE inch sized angular contact ballbearings with a contact angle αααα = 20 ° whenused individually, however, the factor 1, 14must be replaced by 0, 57.
