Keep your elevators running smoothly with NIBL bearing solutions

21

An elevator or lift  are  vertical transportation that moves people or goods between floors of a building, vessel, or other structure. Elevators are powered by electric motors that either drive traction cables or counterweight systems like a hoist, or pump hydraulic fluid.

In agriculture and manufacturing, elevator like conveyor device used to lift materials in a continuous stream into bins or silos. Example, chain and bucket elevator

The most important bearing types for Elevator Systems are as follows :

Deep Groove Ball Bearing(DGBB) :

  • Suitable for robust operation and require little maintenance.
  • Uninterrupted raceway shoulders.
  • Non Separable design & can support radial and axial loads.
  • Different sealing options like seals or shields available.
  • Application used Traction Machines

 

Spherical Roller Bearing (SRB) :

  • Self-aligning design helps to withstand extreme conditions to compensate for drive shaft deflection, which can lead to edge stresses.
  • Internal design enables them to withstand High Radial load and able to accommodate axial loads acting in both directions.
  • Most types have circular groove and lubricating holes in the outer ring, for effective lubrication.
  • Application: Traction Machines.

 

Angular Contact Ball Bearing (ACBB) :

  • Sustain significant unidirectional axial load together with radial load.
  • Bearings with suffix E are designed for higher load ratings and better performance.
  • Inner, outer races and balls are manufactured from high quality bearing steel for optimum performance.
  • Single row angular contact ball bearings are self-retaining units.
  • Rigidity of single row angular contact bearings increases by preloading,
  • Application :Worm Gear Unit
