Tandem thrust cylindrical roller bearings consist of several single-stage thrust cylindrical roller bearings, outer spacers, inner spacers, and a shaft. They feature a simple and compact structure, save installation space, are easy to install and debug, provide uniform load distribution, are wear-resistant, have low vibration and noise, long service life, and high axial load capacity. They have been applied in most twin-screw extruder gearboxes and have become a core component of twin-screw extruders. Our company can provide two-row, three-row, four-row, five-row, six-row, seven-row, and eight-row tandem thrust cylindrical roller bearings, including shaft-type and sleeve-type designs, as well as custom processing and design according to customer size requirements. Customers can select the required bearing model based on screw center distance, space constraints, and load capacity.
