The three-row roller slewing bearing is the slewing bearing with the strongest load-bearing capacity. The inner and outer rings are equipped with three rows of cylindrical rollers, which can withstand radial loads, axial loads and overturning loads, improving structural strength and operational reliability. The three-row roller slewing bearing can provide internal or external integrated transmission devices.
Design Features: The LTZC three-row roller slewing bearing boasts the highest load-bearing capacity among all slewing bearings. It employs three independent rows of rollers, with the upper and lower rows bearing loads at a 90° angle, ensuring ample clearance for each roller and guaranteeing smooth operation and precise rotation.
Bearing manufacturing : The inner and outer rings of the LTZC three-row roller slewing bearing are typically made of materials such as 42CrMo, 50Mn, and 45# steel, undergoing quenching and tempering treatment to achieve a hardness between 170HB and 340HB, ensuring durability and a long service life. The rolling elements are typically made of GCr15 or GCr15SiMn bearing steel, with a hardness of 58-62HRC. The cage is usually made of nylon, and the seals are typically made of butyl rubber or fluororubber.
Bearing Applications: Three-row roller slewing bearings are robust in structure and large in size. They are typically used in large, heavy-duty equipment such as bucket wheel excavators, wheeled cranes, truck cranes, wind turbines, and other heavy machinery.
Custom Bearings: The LTZC engineering team can customize slewing bearings according to customer equipment requirements and provide bearing CAD drawings. If parameters are unclear, we can conduct on-site surveys and develop a professional bearing selection plan. We also support alternatives to international brand bearings, ensuring reliable performance and stable delivery times.
