Cylindrial Roller Bearings NUP300 Series

Cylindrial Roller Bearing NUP300 Series in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row Cylindrical Roller Bearings have high radial rigidity and are used primarily for precision machine tools.These bearings are commonly separable and easy to mount and dismount.

The radial load that a Precision Roller Bearing NUP300 Series is able to carry is, on a par of size, greater than that of a Ball Bearing. A variant of the roller bearing is the needle roller bearing, whose rolling elements is smaller and consequently takes up less space.

RunFine cylindrical Roller Bearings are classified into single row, double row and multi-row cylindrical roller bearings. We also have bearings with cage and full complement assembly. Cylindrical roller bearings with cage have high radial load carrying capacity, operating at high speed. Full complement cylindrical roller bearings can accommodate even higher radial loads, but at low and moderate speed.

RunFine single row cylindrical roller bearings come in N, NJ, NU, NUP designs. Regarding double row and multi-row assemblies, please contact RunFine Technical Support.
