Slewing ring for large marine equipment
Split Three-Row Roller Slewing Bearings
Request a Quote
Split three-row roller slewing bearings are engineered to manage the substantial demands of heavy-duty marine applications. Unlike conventional bearings, these feature segmented inner and outer rings that enable easier transportation and on-site assembly of large-diameter components. This design is necessary to ensure that equipment such as full-rotation floating cranes and large marine cranes can handle significant axial loads, radial forces, and overturning moments with maximum stability and efficiency.
Our standard material of choice is 42CrMo4 steel, renowned for its durability and resistance to wear, with induction-hardened raceways to enhance performance under high stress. However, we offer a range of materials and custom options tailored to specific operational requirements, ensuring that each bearing meets the unique challenges of your marine projects.
Manufacturing Capability
Our manufacturing capability for split three-row roller slewing bearings is designed to accommodate the production of bearings with a maximum outer diameter of 20 meters, ensuring we can meet even the most demanding size requirements. The gear module reaches up to a maximum of 32mm, allowing for precise customization based on client specifications.
(We also offer tailored solutions for non-standard products to suit specific operational needs.)
Case Studies
A 15-meter diameter ultra-large slewing bearing was successfully deployed in the crane of a 2000-ton wind turbine installation vessel at the Three Gorges project.
LYXQL’s split three-row cylindrical roller bearing is specially designed for a pile-driving platform crane, with the largest diameter reaching 18 meters.
LYXQL’s split three-row cylindrical roller bearing is used in 1600-ton pile-driving platform crane.
