CPM 2168 Double Row Cylindrical Roller Bearing 40x57.81x34

Industrial Applications

The CPM 2168 40x57.81x34 double row cylindrical roller bearing is designed for demanding industrial applications where high radial load capacity, precise shaft guidance, and compact assembly are required. The bearing is manufactured by CPM, a well-known Italian brand recognized for precision engineering and consistent quality.
This bearing is commonly used in gearboxes, production machinery, special-purpose machines, drive systems, and assemblies where space optimization and structural rigidity are critical. The design without an outer ring allows direct cooperation with a properly machined bearing housing, reducing overall dimensions of the bearing unit.

Key Advantages

The double row cylindrical roller design ensures uniform load distribution and excellent operational stability under high radial loads. Cylindrical rollers provide a larger contact area compared to ball bearings, resulting in high durability and extended service life in continuous-duty applications.
The absence of an outer ring enables the housing to act as the raceway, increasing system stiffness and minimizing vibration. This solution is particularly valued in heavy-duty industrial applications where reliability, accuracy, and repeatable performance are essential.
