110 Series Slewing bearing

The 110 series is a dedicated line of single-row crossed roller slewing bearings manufactured without integrated gearing, offering a pure rotary support solution for applications where external drive systems are independently configured. This non-geared design provides maximum flexibility in drivetrain selection, allowing engineers to pair the bearing with a wide variety of motors, pinions, friction drives, or belt-driven mechanisms without being constrained by a fixed gear specification. The 110 series is prized for its simplicity, versatility, and exceptional load-handling characteristics.



Typical Application Areas

Turntable bearings for conveyor systems and sorting lines

Rotary indexing tables in automated assembly and packaging machinery

Positioning platforms for robotics and welding equipment

Crane slew rings with separate pinion drives or cable drum arrangements

Radar antenna bases and satellite communication pedestals

Medical diagnostic equipment requiring low friction and high accuracy

Solar photovoltaic trackers and concentrated solar power systems

The 110 series is founded on the single-row crossed roller principle, featuring cylindrical rollers arranged in an alternating orthogonal pattern within a single raceway. This configuration enables the bearing to simultaneously support radial loads, bidirectional axial forces, and tilting moments through a single, compact assembly. The line-contact geometry between rollers and raceways delivers significantly higher rigidity than ball-type slewing rings of comparable dimensions, making the 110 series particularly effective in applications requiring structural stiffness and positional stability.

In contrast to geared counterparts, the 110 series presents smooth inner and outer ring surfaces on both the bore and circumference. The absence of gear teeth simplifies the ring geometry, allowing for a more uniform cross-section and reduced manufacturing complexity. This non-geared design also eliminates concerns related to tooth wear, backlash, and gear lubrication, focusing maintenance exclusively on the bearing raceway itself.
