Product Introduction

NF series single row cylindrical roller bearings are designed with a single rib outer ring and double rib inner ring. This structure allows the bearing to carry heavy radial load and limited one-way axial load, making it suitable for shaft one-way axial positioning in medium to high speed applications. The separable inner and outer rings simplify installation, disassembly and maintenance, especially for gearboxes, electric motors, machine tools and industrial reducers.

FAQ

What is NF series cylindrical roller bearing?

NF series is a single row cylindrical roller bearing with single rib outer ring and double rib inner ring. It is mainly designed to carry heavy radial load and limited one-way axial load, suitable for one-way axial positioning of the shaft.

What is the difference between NF and NJ bearings?

The main difference is the rib structure. NF has a single rib outer ring and double rib inner ring, while NJ has a double rib outer ring and single rib inner ring. This means they support opposite directions of one-way axial positioning.

What is the MOQ for NF series bearings?

Stock sizes can accept small trial orders. Large dimension models usually require bulk quantity. Please send your model list and quantity so we can provide exact MOQ, price and delivery time.

Can you supply P6 precision grade NF bearings?

Yes. P0 is standard production, and P6 precision grade is available upon request. Higher precision will affect unit price and production lead time.

Are NF bearings interchangeable with other brands?

Our NF series dimensions follow international ISO standards, so they are generally interchangeable with standard counterparts. For critical high-speed or high-temperature applications, please confirm clearance, cage type and tolerance requirements.

What trade terms can you accept?

We support FOB, CPT, CFR and CIF terms. We can work with your designated forwarder or arrange shipping service according to your requirements.

Category Overview

Cylindrical Roller Bearings are radial rolling bearings with cylindrical rolling elements that make line contact with raceways. They feature high radial load capacity, high rigidity, high-speed capability, and low friction.Most types can accommodate axial displacement between shaft and housing, and some structures allow carrying axial loads. They are widely used in motors, gearboxes, pumps, compressors, machine tools and other heavy‑duty rotating equipment.

Our Series Breakdown

We offer a complete range of cylindrical roller bearing series to suit different positioning and load requirements:

Series	Features	Typical Applications
NU Series	Floating bearing, free axial displacement, high radial load	Motors, fans, general machinery
NJ Series	Locates shaft in one axial direction, high rigidity	Gearboxes, reducers, machine tool spindles
NUP Series	Locates shaft in both axial directions, fixed positioning	Heavy gearboxes, compressors, pumps
N Series	Outer ring with two ribs, inner ring without ribs	General industrial transmission equipment
NF Series	Single-direction axial location, compact structure	Small‑to‑medium gearboxes and motors
RN Series	Without outer ring, fits directly into housing bore	Hydraulic pumps, construction machinery
RNU Series	Without inner ring, fits directly onto shaft	Special transmission mechanisms, compact equipment

Core Advantages

Extremely high radial load capacity and strong impact resistance
High rigidity and excellent high-speed performance
Low friction, stable operation, long service life
Allow axial thermal expansion of shaft (floating types)
Separable structure for easy installation and maintenance
Available in open, sealed and precision grades

🛠️ Typical Applications

Widely used in electric motors, gearboxes, reducers, pumps, compressors, machine tool spindles, fans, rolling mills, automotive transmissions, and other heavy‑duty industrial machinery.
