This type of bearings is designed for high axial and relatively small combined loads. Their design provides for compensation of the skew of the shaft up to 3%, without reducing the performance of the rotation unit. The bearing consists of two rings and asymmetric rollers fixed by a cage raceway. These products are not designed for very high rotation speeds, but they have a large load capacity and excellent resistance to wear. For ease of installation and maintenance, these parts are most often manufactured collapsible.
