NUP244-EM Single Row Cylindrical roller bearing

Short Description:

Single-row cylindrical roller bearings with a cage comprising cylindrical rollers caged between a solid outer and inner ring. These bearings have a high level of rigidity, can support heavy radial loads and are suitable for high speeds. The inner and outer rings can be fitted separately, making installation and removal a simple process.

The outer ring of an NUP cylindrical bearing has two fixed ribs, whereas the inner ring of the cylindrical bearing has one fixed rib and one loose rib. This means that the NUP cylindrical bearing is able to axially locate the shaft in both directions.
