Reliable Excavator Swing Bearings from China

The slewing bearing device is a new type of slewing product, usually called a slewing bearing, in which the basic structure of the slewing ring is mainly composed of ferrules and rolling elements, cages, and sealing rings. Since the core component adopts the slewing ring, the light, and thin slewing ring can bear the axial force, the structural radial force of the slewing ring bearing, and the overturning moment at the same time.

The excavator can turn left and right during work, and it is inseparable from the slewing device. The slewing bearing is an important part of the slewing mechanism. Since the slewing bearings of excavators generally work under heavy load conditions, and the working environment of excavators is relatively harsh, the slewing bearings are prone to failure. Excavator slewing bearing manufacturers remind you that in order to ensure the excellent performance of excavator slewing bearings, regular maintenance is essential.

The rolling elements of the slewing ring are made of overall hardened carbon chromium bearing steel. The slewing bearing ring is made of surface hardened steel. When the user has no special requirements, it is generally made of 50Mn steel. However, sometimes in order to meet the needs of the host in some special applications, other grades of surface can also be selected according to the specific conditions of use provided by the user. Hardened steel, such as 42CrMo, 5CrMnMo, etc. The precision-made rolling elements make the relative rotation and load transmission performance between the inner and outer rings more remarkable. Usually balls or rollers are made of hard chrome. The size of the rolling elements is better suited to handle the expected stresses and evenly distributed loads on the inner and outer rings, and to reduce the rotational resistance to a greater extent.
