Double Row Full Complement Cylindrical Roller Bearings - Designs and Variants
NNCL Design Bearings
Double Row Full Complement Cylindrical Roller Bearings with NNCL design are designed for high radial load capacity and can accommodate axial displacement in both directions. They are often used in applications like heavy-duty gearboxes and steel processing equipment where axial movement is a requirement.
NNCF Design Bearings
NNCF design bearings are double row, full complement cylindrical roller bearings that feature an integral flange on the inner ring and are designed to handle high radial loads and limited axial loads. These bearings are commonly used in construction machinery and mining equipment due to their robust design and load-carrying capacity.
NNC Design Bearings
NNC design bearings offer high load capacity and axial displacement in one direction, making them ideal for applications such as rolling mills and paper machinery. Their ability to support heavy radial loads makes them a popular choice in demanding industries.
NNF Design Sealed Bearings
NNF design sealed bearings are full complement cylindrical roller bearings with integral seals that provide protection against contamination. They are commonly used in applications where lubrication retention and contamination protection are critical, such as marine propulsion systems and wind turbines.
