The function of Application
NU series is floating end bearing.
NJ series is one directiion axial load.
NUPseries is fixed position bearing.
N series is shaft expansion.
NF series is axial load support.
NN series is high rigidity application.
There are different on cage:
M means brass cage, which high temperature resistance. For example NU204M
EM means reinforced rollers with brass cages, enlarged rollers, and enhanced load-bearing capacity.
E means enhanced roller, optimized roller, steel cage, if M is not indicated, it referes a stamped steel cage.
TN/TN9 means Nylon cage, suitable for medium and low temperature, low noise, not resistance to high temperature.
J means steel plate stamping cage, iron frame, economy type.
There are some clearance:
C1 means extremely small clearnace.
C2 small clearnace
N/A: means normal clearance C0, it can not show.
C3 large clearnace, for motor, high temperature, high speed, extensive use.
C4 more larger clearance
C5 the most largest clearance.
There are some level o precision
P0 normal
P6: P6 precision
P5: P5 precision
P4: P4 high-precision machine tool use, for example: NU1012 P5
Special suffix:
VA: Specialized bearings for high-temperature conditions, with unique heat treatment, resistance to high temperature.
S0: high-temperature resistance size stabilization treatment, (150°C), S1(200°C).
N: outer ring with stop solts; NR: outer ring with stop slot+stop ring set.
Different flange designs provide different axial positioning capabilities and installation solutions.
Take action, what item of cylindrical roller bearing do you need? Let us send the quotatio for you reference.
The Feature of Cylindrical Roller Bearing
1. High radial load capacitiy, large line contact area between rollers and raceway, suiable for heavy load applications;
2. High speed performance, low friction design, suitable for high-speed rotating equipment;
3. High Rigidity, excellent load stability, reduce shaft deformation;
4. Easy installation, seperable inner and outer rings, easy maintenance;
There are Gcr15 bearing steel, stainless steel and high temperature material. And steel cage, brass cage and Nylon cage with P0, P6, P5, P4 quality level for customer selection.
