Hub unit

Driving reliability for elevators and escalators

For elevator and escalator manufacturers, avoiding contamination, extending component lifecycles, reducing noise and vibration and reducing assembly procedures and are all key goals. The SKF hub unit can help achieve all of them.

The solution integrates a wheel hub unit into the input shaft of the worm gear, which is directly connected to the electric motor. The integrated bearing unit consists of a double row angular contact bearing equipped with radial seals and special grease. Factory sealed to prevent contaminant ingress, the hub bearing unit can accommodate the heavy axial loads caused by the gear meshing, and also carry the radial loads by supporting the shaft. Benefits include: 
  • Higher reliability of rotating parts
  • Extended bearing service life
  • Reduced noise and vibration levels
  • Fewer components for faster assembly
