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.
Slewing Bearing Features: Three-row roller slewing bearings have a higher load capacity than crossed roller slewing bearings. 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.
Slewing Bearing Applications: The three-row cylindrical roller slewing bearing is designed to withstand extremely large radial/axial/tilting combined loads. The contact area and contact points between the rolling elements and raceways are far greater than those of single/double-row bearings. It is not designed for high speeds, but is primarily suited for slewing mechanisms in cranes, excavators, port machinery, and wind turbine mainframes, where rotational speeds are low (typically operating speed < 50 r/min, maximum speed < 200 r/min) and loads are extremely heavy.
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.
Customized Bearings: The LTZC engineering team can customize slewing bearings according to customer equipment requirements andprovide bearing CAD drawings. If parameters are unclear, we can conduct on-site surveys and develop a professional bearing selection plan. We also supportalternatives to international brand bearings, ensuring reliable performance and stable delivery times.
