90mm Flanged Series 32 Internal Gear

FIG32 Series Flanged Internal Gear

A series of internally geared flanged bearings with constant height of 90mm ranging from 1100mm to 1600mm outer diameter with an internal spur gear. (We can offer 2000 mm on special order)

Within the QCB® range we offer

  • The widest size range
  • Metric or inch sizes
  • High precision bearings with reduced internal clearance and improved radial runouts
  • Non standard drilling pattern

Typically used in large conveyor systems or ship loaders where the full strength of a solid section, large diameter slewing ring is unnecessary.

 * - suffices dependent on final bearing specification e.g. FIG 1200 32 03 AALM


From 2015 all QCB® geared beairngs wil lbe manufactured in 42CrMo4 for superior gear strength.

Grease points

All bearings are supplied with 6 grease nipples on the outer ring, DIN 71412A M10x1. Variations exist!


Load and bolt limit curves

Bearings should operate within the prescribed triangular load area at all times.

The bolt limit curve is based on the use of Grade 8.8 bolts. An improvement to this can be achieved with the use of Grade 10.9 bolts, but only after approvaly by the NBC Technical Department.
If the load is suspended, or the axis of rotation is not vertical, refer the application details to
Units: Y-Axis - Moment load in KNm; X-Axis - Axial load in KN
