Integrated Three-Row Roller Slewing Bearings
Request a Quote
The integrated three-row roller slewing bearings are designed to handle the significant axial, radial, and overturning loads typical in large marine equipment like full-rotation floating cranes and heavy-duty ship cranes. This bearing type is constructed with inner and outer rings, rollers, cages, and seals, with variations in the size and length of the rolling elements to accommodate the large forces involved. The large diameter and roller size necessitate high precision in design, equipment, and manufacturing processes.
Basic Information
- Material: Standard material is 42CrMo4, with the raceways undergoing induction hardening. Custom materials are available based on specific customer requirements.
- Manufacturing capacity: The largest outer diameter of integral slewing bearing is up to 12 meters, with maximum gear module size of 45mm.
- Customization: Non-standard products can be customized to meet specific client needs.
Types Available
This bearing type is available in three main structures: internal gear, external gear, and non-gear. Each variation is constructed with the same foundational components, including the inner and outer rings, rollers, cages, and seals, but tailored to meet specific application needs in large marine equipment.
