XA120235N External Gear Crossed Roller Slewing Bearing 171×318.8x40mm

Product Overview

Unlike conventional ball bearings that are limited to single-direction loads, the XA120235N features crossed cylindrical rollers arranged at 90° intervals within a single raceway. This unique configuration allows the bearing to simultaneously withstand radial loads, axial loads, and overturning moments—all within a compact, space-saving design. The external gear teeth on the outer ring enable direct integration with drive systems, eliminating the need for separate gear components and simplifying mechanical design.

Key Features:

• Multi-Directional Load Capacity
  The crossed roller design enables the XA120235N to simultaneously handle radial, axial, and moment loads. This capability reduces the number of bearings required in an assembly and simplifies mechanical design.

• Exceptional Rigidity and Accuracy
  The crossed roller geometry provides significantly higher rigidity than ball bearings, minimizing deflection under load and maintaining positioning accuracy. The P5 precision grade ensures smooth, accurate rotation with minimal runout.

• Compact, Space-Saving Design
  With a slim 40 mm profile, the XA120235N is ideal for applications with limited installation space. The integrated gear teeth further reduce system complexity by eliminating separate gear components.

• Direct Drive Integration
  The external gear teeth allow direct connection to pinion drives, simplifying mechanical design and improving transmission efficiency.

• Reliable Sealing and Lubrication
  Double lip seals protect against contamination, while the two grease nipples ensure easy relubrication.

• Long Service Life
  The combination of GCr15 bearing steel, precision manufacturing, and effective sealing delivers extended service life even in demanding industrial environments.
