Are single row cylindrical roller bearings and have two fixed ribs on the outer ring and one smooth inner ring. This design allows an axial displacement in certain limits, of the shaft in relation to the housing. Therefore, NJ Series rolling bearings are used in non-locating bearing units. Also, the NJ Series bearings have no virtually thrust capacity.

Design Attributes

The design has a cylindrical inner ring and two ribs on the outer ring, making type NJ bearings well suited for use as floating bearings.
Separable components simplify mounting and removal.
Accommodates axial expansion and contraction.
It provides axial displacement between rings with minimum friction while rotating.
Supports heavy radial loads.
Not suitable for applications with thrust loads.


The drawing




Cylindrical roller bearings are available in many designs, series, and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single, double and multi-row full complement bearings (without a cage) and split bearings complete the international standard assortment provided here.

Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. CHIK high-capacity cylindrical roller bearings combine the high load-carrying capacity of a full complement bearing with the high-speed capability of a bearing with a cage.


1. Cylindrical roller bearings feature high radial load because the rollers and raceway are in linear contact
2. The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft axial movement, to a certain extent, relative to the housing position
3. The NJ and NF types carry a certain degree of axial displacement in both directions so they also use
das free side bearings
4. Models available: NU, NG, NUP, N, NF, NH, NNU, NIV
5. Moreover, we can manufacture these bearings according to customer's drawings and samples.
Single row cylindrical roller bearings as for the ring ribs divided into N-type, NU type, NJ and NUP type and so on. Cylindrical roller bearings withstand heavily capacity of the radial load. But according to the structure of ring ribs can also be under some one-way or two-way axial load.NN and NNU type double row cylindrical roller bearings are compact structure, which with strong rigidity and bears load capacity. Even if it has to bear a heavy load, its deformation is small. It mostly used for machine tool spindle bearing.
FC, FCD, FDCP-type four-row cylindrical roller bearings can bear greater radial load, mostly using for rolling mill and other heavy machinery.
