ULTAGE spherical roller bearing

ULTAGE spherical roller bearing is new products by NTN and SNR,ULTAGE bearing offer a wide range of spherical roller bearing for the customers demand,they can design and produce different cage versions.from 25mm bore to 2180mm outer diameter can be found in ULTAGE,

SNR spherical roller bearing was named SRO which are created by Swiss blacksmith in 1916, and it become SNR Societe Nouvelle de Roulements" in 1946,SNR developed its commercial network in France and Europe,and become No.1 for bearing in France and 4th in Europe in 1956,SNR has held the speed record with the fastest train in the world in 1981,and now SNR bearing are widely used in high quality and precision application demand like train,aerospace,automotive.

NTN was founded began research and manufacture of ball bearings at Japan in 1918, NTN spherical roller bearing appeared on the market in 1922,NTN expand his business in Germany since 1961,NTN established NTN France S.A. and NTN Bearing UK ltd in 1964,NTN group completed full certification for the ISO9000 series in 2000,and all NTN plants completed certificated for the ISOTS16949 series in 2005.

From above mentioned,you can see SNR and NTN have the same history and background,so its easy conbined together to become stronger worldwide and to improve their position in Europe,
Ultage spherical roller bearing have 4 cages and 5 specific solutions,

1.EA series cage,its pressed steel cage,the same with EASIER spherical roller bearing CC Cage
2.EM series and L1 series ,machined solid brass cage,with same with EASIER bearing CA cage
3.EF800 series ,special design cage for vibrattion screen, the same with CCJA cage of EASIER
4.EG15 series,polyamide cage,the same cage with EASIER E1.TVPB bearing

The internal design of double row spherical roller bearing enables them to carry very high capacity from both directions,it consist of inner ring(raceway on outside,tapered bore or cylindrical bore),outer ring(spherical raceway inner side and lubrication groove and lubrication hole outside),double row symmetrical spherical rollers held in cages.

NTN-SNR"Premium Quality" spherical roller bearings can supply Optionmised design,no central rib but not 240 and 241series,more larger and longer rollers than traditional design,so its increased load capacities, let us see some new features of NTN-SNR spherical roller bearing,
surface optimisation,steel cage with surface treatment,noise reduction, reduced friction torque, increased operating speeds, increased service life,improved performance,reduced operating costs,

SPZ spherical roller bearing

Today let us talk about double row spherical roller bearing market in Russia,of course you will remember SPZ brand in your brain. yes you are right,SPZ brand is famous in russia and all over the world,its belong to Samara Bearing Plant who founded in 1935,this factory name was transformed in 1996 when its open joint stock company.SPZ GROUP can make bearings with sizes from 50 mm to 4000 mm,

SPZ double row spherical roller bearing occupy very important place in Russia bearing industry,the same with ZWZ bearing in China,as the other brand spherical roller bearing,this brand bearing also carry very high radial load capacity than the other types and similar size,they are able to offset substantial misalignments and shaft deflection,and take combined loads,the bearing hold shaft aligned in both directions,double row spherical roller bearing are used in devices as exhaust blowers,reduction gearbox,rolling mills,high performance fans,pumps,the cage of this kind of bearing have solid bronze and brass material,but its suffix have some different with the international market standard,so let me explain as follows:

Tolerance Class:

--0 normal accuracy

--6 improved accuracy

--5 higher accuracy than 6

cage material:

--Л brass

--Б tinless bronze

--Д aluminum alloy

--E  plastic

Material of bearing elements:

--hardened steels (ШХ15… );

--carburized steels (20X2H4A);

--full hardened steels with regulated hardening (ШХ4…).

 

--001 two-row spherical ball bearing with cylindrical bore, complete, with retainer – main type

--003 – double-row spherical roller radial bearing with ribs on inner ring and asymmetrical rollers

--013 – double-row spherical roller radial bearing with adapter sleeve – main type.

For example, 13530

--023 – single-row spherical roller radial bearing. For example, 23508

--053 – double-row spherical roller radial bearing with symmetrical rollers, no ribs on inner ring. For example,53608.

--073 – double-row spherical roller bearing with withdrawal sleeve

--083 - double-row spherical roller bearing with seals

--093 - double-row spherical roller bearing with withdrawal sleeve, non-standard dimensions

--113 – double-row spherical roller bearing with tapered bore

--153 – double-row spherical roller radial bearing with symmetrical rollers and tapered bore

--353 – double-row spherical roller bearing with symmetrical rollers, no ribs on inner ring, with adaptersleeve.

--753 – double-row spherical roller radial bearing with symmetrical rollers, withdrawal sleeve and no ribs on inner ring.

--953 - double-row spherical roller radial bearing with symmetrical rollers, withdrawal sleeve and no ribs on inner ring, non-standard dimensions.

SPZ company can manufacture the bearing according to customers drawing,just like the bearing 538/1320XK,this is a double-row spherical roller bearing with two pieces inner and outer rings,it is used in Steel Mills converters and more heavy duty environments,so if you have some special demand about spherical roller bearing, SPZ can meet your demand,more question about SPZ,please contact with XRB,you can find the best solution here.
