90mm Flanged Series 32 slewing rings

Similar in construction to it's smaller cousins (the 56FLS20 Series) the 90F32 range maintains a 90mm section height across a diameter range from 1100mm to 1600mm outer diameter (with special design to 2000mm), with ungeared, internally and externally geared versions. The usual ball diameter is 32mm or 1.1/4".

These bearings can generally be considered interchangeable with thise made by ither manufacturers.

From 2015 all QCB® geared slewing rings will be manufactured in 42CrMo4 steel for superior gear strength when compared to rival products.

Within the QCB® range we can offer 

  • Non standard drilling patterns
  • VITON or labyrinth seals
  • Reduced internal clearances and improved runouts if required
  • Non standard lubricants

On the sub pages we tabulate the dimensions of each series. Drawings are available for download in PDF format. CAD and 3D models will be made available on request.
