Cylindrical roller bearing features:
1. Roller and groove for line contact or repair referral contact, radial load capacity, is designed to withstand heavy load and impact load.
2. Small friction coefficient, suitable for high speed, limit rotational speed close to deep groove ball bearing.
3. N-type and NU type can axial movement and can adapt caused by thermal expansion or installation error and shell the shaft of relative location changes, can make free use of the bearing. 4. The hole of shaft or block the demand is higher, bearing processing after installation relative skewed to outer ring axis and kept under strict control, lest cause contact stress concentration.
5. Inner circle or their cups are separable, convenient in installation and removal.


Cylindrical Roller Bearing without Inner Ring – Model RNU

This kind of bearing contains only the two capped caged outer ring, the full sets of rollers and cage, and it can be used in some small parts which are limited in the radial direction, and the hole formed of the inner surface to the rolling surface. If the hardness and roughness is the same with the rings of bearings, then the loading rate is the same with the model NU. While if the customer has special requirements on the Ew tolerance, it can be confirmed specially.


Production Description:

Cylindrical Roller Bearings are separated type bearings, of which installation and removal is very convenient. Cylindrical Roller Bearings divided into single, double and four row.

According to the number of columns, cylindrical roller bearings can be divided into single, double and so on. Single row cylindrical roller bearing with cage is applied more usually. In addition, there are single or double row filled rollers and other structures cylindrical roller bearings.

Single row cylindrical roller bearings with the Rings Ribs can be divided into different types, such as N-type, NU type, NJ type, and NF-NUP type. Cylindrical Roller Bearings bear big radial loading, and can withstand a certain one-way or two-way axial load according to the structure of Ring Ribs.

NNU type and NN type double-row cylindrical roller bearings have compact structure, high rigid, big carrying capacity, small the load deformation, that is mostly for the machine spindle bearing.

FC, FCD, FCDP four cylindrical roller bearings can withstand great radial loading, which is more for the mill, and other heavy machinery

Large and medium-sized motor, locomotives, spindle, internal combustion engines and generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery
