This advanced bearing structure is primarily composed of an inner ring, outer ring, three rows of rollers, a cage (separation block), a sealing device, and additional components. The innovative design features separate upper, lower, and radial raceways within its three-row raceway system. This configuration allows the two sets of horizontally positioned rollers to effectively carry axial loads and overturning moments, while a single set of vertically aligned rollers manages radial loads. As a pure bearing structure devoid of gears, it provides exceptional performance in applications requiring substantial load support without the need for gear transmission. Designed for heavy-duty use, this system is ideal for industries seeking robust solutions from reliable China Suppliers and competent Factory production.
