N / NU Series
Однорядная Цилиндрические роликоподшипники
20–500mm Bore | N (Ribbed Inner) | NU (Ribbed Outer) | P5/P4/P2 Grade
The N and NU series offer the simplicity and economy of single-row cylindrical roller bearing designs — available in N (ribbed внутреннее кольцо), NU (ribbed наружное кольцо), NJ (ribbed inner + single-rib outer), and NUP (ribbed inner + loose фланец) configurations. Разъёмная ring design in all variants позволяет straightforward handling during assembly and maintenance.
Compact Однорядная Цилиндрические роликоподшипники for Moderate Радиальная нагрузкаs
Luoyang Songju N and NU series single-row cylindrical roller bearings provide reliable radial support in a compact, economical package. Доступно в multiple ring configurations — N (ribbed внутреннее кольцо, smooth outer), NU (smooth inner, ribbed outer), NJ (ribbed inner + single-rib outer for limited axial location), and NUP (ribbed inner + loose фланец for full axial location in both directions) — to match diverse spindle and machinery design requirements.
Разъёмная ring design — where the ribbed ring and roller assembly can be separated from the smooth ring — облегчает independent mounting of each bearing component. This is particularly advantageous in blind корпус applications or where press-fit conditions require sequential mounting of the внутреннее кольцо onto the вал and the наружное кольцо into the корпус.
Standard models are manufactured from подшипниковая сталь GCr15 in P5, P4, and P2 класс точностиs. The N10/NU10 dimensional series имеет a thin поперечное сечение for space-constrained spindle designs, while N2/NU2 and N3/NU3 series provide progressively heavier поперечное сечениеs for higher load requirements. Доступно с обработанные латунные сепараторы (M suffix), штампованные стальные сепараторы (standard), or высокоскоростной resin cages for elevated speed applications.

Почему выбирают Luoyang Songju N / NU Series Цилиндрические роликоподшипники
Compact single-row design — the economical choice for moderate radial loads with flexible mounting configurations
Four Configuration Options
Choose N (ribbed inner), NU (ribbed outer), NJ (inner ribs + single outer rib), or NUP (inner ribs + loose outer фланец) to match your exact вал and корпус interface requirements. Each configuration обеспечивает different combinations of axial location and thermal expansion accommodation.
Separable Ring — Independent Mounting
All N/NU/NJ/NUP variants feature separable rings — mount the внутреннее кольцо on the вал and the наружное кольцо in the корпус independently. Идеально для blind корпус applications and press-fit conditions that require sequential bearing component installation.
Wide Dimensional Series Range
From ultra-thin N10/NU10 series for space-constrained spindles to тяжёлый N3/NU3 series for maximum грузоподъёмность — select the exact поперечное сечение your design requires. Multiple dimensional series enable optimization for either minimum envelope or maximum load rating.
High-Speed Capable
Single-row designs with optimized roller profiles and высокоскоростной resin cages achieve higher предельная скоростьs than double-row equivalents. N10/NU10 thin-section series in particular excels in высокоскоростной spindle applications where minimizing rotating mass is critical.
Premium GCr15 Bearing Steel
Rings and rollers manufactured from вакуумно-дегазированная GCr15 (100Cr6/52100) steel. Through-hardened to 58–64 HRC with controlled retained austenite content for dimensional stability under varying loads and рабочая температураs.
NTN / NSK / SKF Interchangeable
Manufactured to ISO dimensional standards. Direct drop-in replacement for NTN, NSK, SKF, and FAG N/NU/NJ/NUP series single-row cylindrical roller bearings. Competitive pricing with сокращённые сроки поставки from Luoyang.
Отрасли и применения for N / NU Series Цилиндрические роликоподшипники
N / NU серии цилиндрические роликоподшипники are trusted across precision industries worldwide for their unmatched radial performance.
Auxiliary Spindle Support
N and NU bearings provide compact radial support for auxiliary spindles, idler валs, and transmission валs in CNC machine tools. Разъёмная конструкция упрощает assembly in the confined spaces typical of multi-spindle machine configurations.
Gearbox Input & Output Shafts
NU series (ribbed наружное кольцо) is the standard choice for gearbox валs — the наружное кольцо ribs retain the roller assembly while the smooth внутреннее кольцо allows easy вал insertion. NJ and NUP variants provide controlled axial location for helical gear thrust reactions.
Electric Motor Rotor Support
N/NU bearings support motor роторs in industrial electric motors, servo motors, and spindle drive motors. Разъёмная конструкция упрощает motor assembly — mount the наружное кольцо in the end bell, then insert the ротор-and-inner-ring assembly as a unit.
Pump & Compressor Shafts
Однорядные цилиндрические роликоподшипники handle the radial loads of centrifugal pump, compressor, and blower валs. NU bearings at the floating end accommodate thermal вал expansion while the locating end uses an NJ or NUP bearing for axial positioning.
