It have single row, double row, four row even six row rollers' type.
Characteristics:
1) Cylindrical roller bearing can be separated by single row,double rows and four rows.
2) This kind of bearing can be submitted to high radial load and some axial load.
3) The rolling element of cylindrical roller bearing is cylinder; the two ends of the external lines have
the corrective slope which can eliminate the contact stress.
the corrective slope which can eliminate the contact stress.
4) NN and NNU design cylindrical roller bearing have high rigid and apply to machines such as millings.
Features:
a.The rollers and rings are line contact, can carry big radial capacity, suitable for bearing heavy load and
impact load.
b.Low friction coefficient, suitable for high speed, limiting speed close to deep groove ball bearings.
c.Inner ring or outer ring is separable, easy to install and dismantle
