Crossed roller slewing bearings provide the highest rotational accuracy in their class. Key features: 90° crossed roller arrangement for maximum stiffness ±0.001° repeat positioning accuracy Compact design with high moment load capacity Ideal for robotics, medical equipment and telescope mounts Standard and custom clearance options available
Four-point contact ball slewing bearings offer versatile performance for moderate loads. Our industrial versions feature: 35° contact angle for balanced load distribution Higher speed capability than roller designs Integrated sealing systems for contaminated environments Common applications: crane slewing rings, wind turbine yaw systems Pre-lubricated for maintenance-free operation
Double-row ball slewing bearings deliver enhanced load capacity and rigidity. Technical highlights: Step bore design for precise axial location 45° contact angle for optimal load transfer Special raceway grinding for smooth operation Primary applications: excavator swing bearings, radar platforms Optional surface hardening up to 60 HRC
Heavy-duty three-row roller slewing bearings represent the ultimate solution for extreme load conditions. Key specifications: Independent load paths for axial, radial and moment loads Dynamic load ratings up to 50,000kN Customizable roller diameters and lengths Essential for mining shovels, tunnel boring machines Special corrosion-resistant coatings available
