Product Description

Cylindrical Roller Bearingsare bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings.As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface.

Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

Types of cylindrical roller bearing:
Single row cylindrical roller bearing: NU, NJ, NUP, NUP series.
Double row cylindrical roller bearings:NNU series.
Four row cylindrical roller bearing:FC series.
Single row full complement cylindrical roller bearing:SL18 series, SL 19 series.
Double row full complement cylindrical roller bearing: SL01 series, SL02 series, SL18 series.
