Roller Bearings are rolling-elements that use rollers for maintaining the separation between the moving elements of the bearing. They are used for reducing rotational friction. In addition to this, they are also utilized for supporting axial and radial loads. They are ideal for supporting heavy and limited loads with their ability to work at moderate to high speeds. These durable and sturdy bearings are utilized in different applications and sectors from power generation, heavy equipment and machinery, manufacturing to aerospace. These equipments can be availed in different internal clearances and retainer choices along with varied bore dimensions up to 900 mm.
