Double-Row Step Bore Ball Slewing Bearings

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
