Balls external gear 01 Series slewing bearing

The LYMC Bearing 01 series is a family of single-row, four-point contact ball slewing bearings featuring an external gear on the outer ring. This series is part of Rollix's light to medium-duty product range and is designed for applications that require combined load support in a compact, cost-effective configuration.



Typical Applications:

Construction machinery such as cranes and excavators

Solar tracking systems

Radar and antenna positioning systems

Wind turbines

The 01 series bearing consists of an inner ring, an outer ring with integral external teeth, and a single row of steel balls with spacers. The raceways are designed so that each ball maintains contact with the raceways at four distinct points, enabling the bearing to simultaneously support axial loads (in both directions), radial loads, and tilting moments within a single row of rolling elements.

The external gear is machined directly on the outer ring, allowing direct pinion drive coupling without the need for a separate gear ring. This simplifies the transmission system and reduces overall component count. Both rings are provided with mounting holes for straightforward bolted installation, making connection between adjacent machine components simple and efficient.

Performance Highlights

  • Combined load capability: Handles axial, radial, and moment loads simultaneously

  • Compact and lightweight: Single-row design saves space and reduces structural weight

  • Smooth rotation: Optimized raceway geometry provides stable operation under load

  • Easy integration: External gear and mounting holes simplify system assembly

  • Available variants: Offered in standard and light series configurations
