Single Row Cylindrical Roller Bearings are mechanical parts that use cylinders instead of balls to lower friction and hold heavy weight.They handle straight side forces very well.You can take the parts apart easily,and they work fast.
This product series features separable inner ring,outer ring or double-flange structures (NU,NJ,N,NF types) for flexible assembly.Equipped with high-strength brass,nylon 66 or stamped steel cages,the bearings can bear limited bidirectional axial loads while carrying huge radial force.Standard raw material is GCr15 high-carbon chromium bearing steel;SUS440 stainless steel customized versions are available for anti-corrosion,cleanroom environments.
Newbeetrans ROBUST series covers a complete dimensional range:inner diameter 120-1320 mm,outer diameter 180-1600 mm,width 28-345 mm.Precision grades include P0,P6,P5,P4 to match general machinery and ultra-precision high-speed equipment separately.Both caged and full-complement roller structures are supplied to satisfy light-medium speed heavy-load demands.
High Radial Load Capacity:The line contact between the cylindrical rollers and the raceways distributes force over a larger surface area compared to the point contact of ball bearings,making them ideal for heavy radial loading.
Separable Design:The inner or outer ring can often be detached from the rest of the bearing assembly. This makes mounting,dismounting,and maintenance significantly easier,especially in tight housing spaces or press-fit assemblies.
Accommodates Axial Expansion:Non-locating designs (such as NU and N types) allow the shaft to move axially relative to the housing. This accommodates thermal expansion and contraction of the shaft without generating unwanted internal axial stresses.
High-Speed Performance:Designed with optimized roller guidance and precision cages (pressed steel,machined brass,or polyamide),these bearings offer low friction and minimal heat generation under high rotational speeds.
Versatile Flange Configurations:Available in multiple structural variations tailored to specific shaft-location requirements:
NU/N (Non-locating):Flanges on only one ring; accommodates axial movement in both directions.
NJ (Semi-locating):Flanges allow the bearing to locate the shaft axially in one direction.
NUP (Locating):Features fixed flanges plus a loose flange ring to locate the shaft in both axial directions.
Electric Motors & Generators:Used on the drive end (DE) of medium-to-large electric motors. They support high radial forces from belt drives or gear couplings while allowing the shaft to expand axially as motor temperatures rise.
Industrial Gearboxes & Transmissions:Installed on high-torque intermediate and input shafts. They handle heavy,continuous radial forces generated by helical and spur gear meshes.
Railway & Transportation (Axleboxes):Crucial in railway vehicle axle journals and traction motors due to their exceptional durability under extreme impact loads,heavy vibration,and high speeds.
Pumps & Compressors:Utilized in heavy-duty centrifugal pumps,screw compressors,and mud pumps where high radial loads and fluid temperature changes demand free axial float on non-locating bearings (such as NU or N designs).
Machine Tool Spindles:Applied in high-precision lathes,milling heads,and machining centers (often using NN or precision single-row variants) to provide superior radial stiffness and minimal shaft deflection under cutting loads.
Wind Turbines:Used in wind turbine gearboxes and main generators to withstand dynamic,fluctuating wind loads and harsh operating conditions.
Steel Rolling Mills & Mining Machinery:Found in conveyor rollers,crushers,and mill drive shafts where heavy impact forces and contaminated environments are common.
