Flanged Slewing Bearings: The Space-Saving Solution for Modern Machinery Designs
What Is a Flanged Slewing Bearing?
A flanged slewing bearing is a variant of traditional slewing rings that features a flange structure on either the inner or outer ring. This design enables more convenient installation by eliminating the need for a separate mounting plate or housing support.
Compact, lightweight, and easy to align, flanged slewing bearings are ideal for applications with space constraints or strict mounting precision requirements. They are commonly used in packaging equipment, robotic arms, small cranes, rotating displays, and automated guided vehicles (AGVs).
Key Advantages of Flanged Slewing Bearings
Simplified Installation
Flanged designs allow for direct bolt-on mounting to a surface or housing. This reduces the need for support rings, minimizes alignment error, and shortens assembly time.
Reduced Structural Footprint
With fewer components and a unified load-bearing surface, flanged slewing bearings contribute to overall space savings. This is critical in compact systems like AGVs, medical imaging tables, and miniaturized automation lines.
Integrated Load Handling
Despite their slim form, flanged slewing bearings support:
Axial loads (vertical pressure)
Radial loads (horizontal forces)
Tilting moments (overturning torque)
Depending on raceway and ball arrangement, they can deliver precise, high-stiffness rotation under demanding conditions.
Cost-Efficient Engineering
Reduced components mean lower material and labor costs. Maintenance is simpler and access is easier, making flanged designs more budget-friendly over the long term.
