390RV5101 bearing size 390x510x290 mm cylindrical roller bearing rolling mill bearing 390RV5101

The roller elements are cylindrical rollers make this kind of bearings can accommodate heavy

load and even very heavy load, mainly to radial loads. The smaller friction between roller

elements and rings make it can very suitable for high speed. There are different types: single

row cylindrical roller bearings: NU series, NJ series, NUP series, N series, NF series etc.

double row cylindrical roller bearings: NNU series and NN series.

The rollers of cylindrical roller bearings are a key component. Their geometry, the

so-called logarithmic profile, provides an optimum stress distribution in the contact zones

in the bearing, their surface finish maximizes lubricant film formation and optimizes

rolling motion of the rollers. The benefits derived from this compared with traditional

designs include enhanced operational reliability and a greater insensitivity to misalignment.
