EB2 Series ext.toothed

The EB2 series consists of high-performance double-row ball slewing bearings with external gear configuration, specially engineered for medium-heavy duty rotary machinery that demands superior load capacity and integrated drive performance. Differentiated from conventional single-row slewing rings, this series adopts a dual-ball race layout and integrated external tooth structure, achieving optimized mechanical balance between structural rigidity, operational stability and transmission efficiency.


Typical Applications:

Medium to large cranes and excavators

Aerial work platforms and man lifts

Wind turbine yaw systems

Solar tracking arrays

Radar and antenna positioning systems

Heavy-duty industrial turntables

Built with precision external involute gears, the EB2 series integrates driving and rotating functions into a single component. The external gear layout allows convenient meshing connection with driving pinions, bringing simpler transmission assembly and more intuitive maintenance compared with internal gear types. All gear teeth undergo precision machining and professional heat treatment, delivering low backlash, accurate meshing and outstanding wear resistance. The reliable gear transmission system ensures consistent torque transmission and responsive rotary motion, fully meeting industrial requirements for precise and efficient mechanical drive.

All standard EB2 series specifications come with pre-machined mounting holes for rapid positioning and hassle-free installation. With a compact and reasonable cross-sectional structure, the bearing achieves higher structural stability and stronger impact resistance than ordinary single-row bearings. It balances heavy-load performance and flexible rotation, featuring low operational vibration and stable running status during daily operation, with remarkable cost advantages in medium and heavy-load industrial application scenarios.
