Double-row cylindrical roller bearings

Description

Cylindrical roller takes on line contact with raceway, and the radial load capacity is large. The cylindrical roller bearing can be subject to heavy load and impact load, and be applicable for high-speed rotation. After improvement of cylindrical roller bearing raceway and rolling element geometry, the cylindrical roller bearing is provided with larger load capacity. The new type structure design of rib and roller end not only enhances the axial rolling element load capacity of the bearing, but also improves the lubricating condition of the contacting area of the roller end and the rib, and the service performance is also enhanced. This type of bearing is mainly applied on medium-sized and high-capacity motor, generator, gas engine, steam turbine, machine tool main shaft, speed reducer, stevedoring and transporting machine and various industrial machines.
