The standard offer also includes
special bearings for electrical units.
From our sales programme we
recommend ball bearings which
can withstand high temperatures
and extreme operating conditions.
You can choose among:
• geometry
(tolerance class of processing)
• cage type (form and material)
• radial internal clearance
(C2, CN, C3, C4, C5)
• type and quantity of dis-
pensed lubricant.
All structural bearings’ compo-
nents are made of high quality
steel. Outer, inner ring and rolling
elements are thermally treated.
Bearings have optimized inner
geometry, which consequently
increases their capacity in radial
direction and decreases the sen-
sitivity for radial deviation and ad-
ditionally enables the best oiling
conditions.
Bearings are available in sealed
edition (protection from dust and
humidity), which means they have
been provided with a lifetime oil-
ing and do not require regular
maintenance.
Rudimental conditions for
assuring rated bearing
properties at a given point of
installation:
• cleanniss
• perpendicularity of planes
to the basic bearing axis
• axis parallelism
• positioning plane
• angles of shafts and/or motor
housings must be chamfered
at the transition into a fit
• raceways of the rotor part
or motor housing must be
needleless, without any con-
tusions, oxide or cracks
• suitable surface processing
of the fit (provides for suit-
able surface roughness).
Bearing suitability:
• High revolution number
• High running accuracy
• Low vibrations and noisiness.
Tips and recommendations
• With each case of mounting of
a new or existant bearing
the basic condition - clean-
niss – must be provided for.
• The bearing is mounted onto a
shaft and/or into a housing by
pressing-on or pressing-in of
both ring simultaneously. This
is done by a unit on the press.
• When dismantling, a spe-
cial dismantling tool is used.
Lastnosti:
• Vzdržljivi
• Zanesljivi
• Nadzorovana kakovost
• Dolga življenjska doba zmanj-
šuje stroške vzdrževanja
• Izdelani po standar-
dnih merah in oznakah
• Cenovno ugodni

Med standardno ponudbo štejemo
tudi posebne ležajev tipe za elek-
tro naprave. Iz prodajnega progra-
ma priporočamo kroglične ležaje
kateri so lahko izpostavljeni višjim
temperaturam in ekstremnim po-
gojem za delovanje.
Pri tem lahko izbirate med:
• Geometrijo
(tolerančni razred obdelave)
• Vrsto kletke (oblika in material)
• Notranjo radialno zračno-
stjo (C2, CN, C3, C4, C5)
• Vrsto in količino do-
ziranega maziva.
Vse sestavne komponente ležajev
so iz kakovostnega jekla. Zunanji,
notranji prstan in kotalna telesa so
termično obdelana.
Ležaji imajo optimirano notranjo
geometrijo, kar posledično pove-
čuje njihovo nosilnost v radialni
smeri in zmanjšuje občutljivost na
kotni odmik ter dodatno omogoča
najboljše pogoje mazanja.
Ležaji so v zatesnjeni izvedbi (za-
ščita pred prašnimi delci in vlago)
kar pomeni, da so doživljenjsko
namazani in ne potrebujejo re-
dnega vzdrževanja.
Osnovni pogoji zagotavljanja
lastnosti na danem mestu
vgradnje:
• Čistoča
• Pravokotnost ravnin na
osnovno os ležaja
• Paralelnost osi
• Pozicionirna ravnina
• Robovi gredi in/ali motorske-
ga ohišja morajo imeti posnete
robove (faze) v prehodu v ujem
• Tekalne površine rotorske-
ga dela ali ohišja motorja
morajo biti brez igel, udar-
nin, oksida in razpok.
Ustrezna površinska obdelava
ujema (zagotovljen pogoj površin-
ske hrapavosti).
Primernosti ležajev:
• Visoko število vrtljajev
• Visoka točnost teka
• Majhne vibracije in šumnost.
Nasveti in priporočila
• Za vsak postopek vgradnje
novega ali obstoječega le-
žaja mora biti zagotovljeno
osnovni pogoj - čistoča.
• Na rotor in/ali v ohišje ga na-
mestimo z natiskovanjem ali
vtiskovanjem obeh prstanov
hkrati. To izvedemo s pomo-
čjo priprave na stiskalnici.
• Pri demontaži uporabi-
mo snemalno orodje.
