HSC bearing units with half-round outer ring for continuous casting machines

HSC bearing units with half-round outer ring for continuous casting machines

This kind of bearing originated from the bearing brand in Japan. It is a special bearing for a continuous casting machine. FV bearings are specifically designed for use in continuous casting machines. They use a full complement cylindrical roller bearing optimized for maximum static load ratings. The rolling surface of the rollers has a crowning feature that helps to distribute the load evenly and prevent stress concentration in specific areas. These bearings are used to support heavy loads and operate at extremely low speeds, making them ideal for continuous casting machines. However, the harsh operating conditions of these machines mean that the bearings are exposed to splashing water and scales.
APPLICATION: CCM rolls

Roll support bearings are essential components used in continuous casting machines. They are subjected to heavy loads and operate at extremely low speeds while being exposed to harsh conditions such as splashing water and scales. 


SCP bearings are used for the fixed side, while SC bearings are used for the free side of the end of rolls, for the intermediate support section of beetle-shaped rolls, such as driving rolls, HSC bearing units with a half-round outer ring are used.


FV bearings are designed specifically for continuous casting machines. They are full-implement cylindrical roller bearings with maximized static load ratings. In order to prevent the buildup of stress in particular spots, it is important to distribute the load evenly; rollers are crowned according to load size on their rolling surface. 


The bearing has a self-aligning mechanism that can absorb roll bending and misalignment caused by heavy loads.

We designed the inner ring to smoothly move axially to accommodate thermal expansion and contraction. Your equipment is in good hands!



The objective of developing the bearing was to enhance the short service life of spherical roller bearings, which are frequently used in continuous casting machines. The inner and outer rings, along with the loose rib, have ribs that enable the bearing to accommodate axial loads resulting from the thermal expansion and contraction of rolls.

We are thrilled to present our exceptional bearing that is meticulously crafted to meet your needs. Our innovative design allows for the perfect balance of thermal contraction and expansion of the roll, ensuring your operations run smoothly. With a focus on quality, we have built the inner ring and roller to move flawlessly in the axial direction, accommodating these changes with ease. 

Our product boasts of a distinctive structure, featuring a half-round outer ring placed on the loaded side only, resulting in a phenomenal 15% increase in the static load rating compared to conventional products. Our compact seal design also plays a crucial role in this increase, making it perfect for your needs. 

Our unique jacket design is a true testament to our commitment to excellence. It adjusts the flow of water and enables high cooling efficiency, even with a lower water flow rate of 55%. Rest assured, our product performs just as well as conventional products, making it a smart choice for you.
