Four point contact ball slewing ring bearing has many different standards for rotational applications, such as mini excavators, tower cranes, truck cranes, and aerial work platforms.
Single-row ball slewing bearing as the most widely used slewing bearing, has a single row of balls that contact the raceway at four points. This structure allows it to handle forces from multiple directions all at once. It is popular for medium-load applications, such as infrastructure construction, mining excavation, cranes, concrete pumps, and other medium-duty construction scenarios.
Single-row ball slewing bearing has two rings (inner and outer) with a single row of steel balls in a four-point contact raceway. It is widely designed for light-to-medium load applications, such as medium excavators, tower cranes, earthmoving equipment, and aerial work platforms.
Single-row ball slewing ring, also as four point contact ball slewing ring, consists of two rings (inner and outer). It is the standard choice for light-to-medium load applications, such as mini excavators, tower cranes, welding positioners, and aerial work platforms.
