Wheel bearings and bearing housings

Wheel bearings and bearing housings

Cleaning solutions for railways components with complex geometries

Continuous stress, long service times and the large distances covered by the trains leave their marks and often also cause damage to wheel bearings. Cleaning and removing grease and oils is absolutely essential for subsequent crack testing and servicing tasks.

Different forms of wheel bearings and their complex geometries complicate the cleaning process. It needs to be able to handle heavy grease deposits and clean hard-to-reach interior spaces.

The cleaning systems must be able to satisfy the corresponding requirements. The OceanRW turntable system and the YukonDA conveyor system are able to handle the challenges posed by wheel bearings and bearing housings, irrespective of whether they are cylindrical roller bearings, spherical roller bearings or other types of bearings.

    Advantages of the OceanRW:

  • Optimal handling and shorter operating times
  • Bearings can be directly placed on parts holders
  • Special nozzle system for all-around, intensive spray cleaning using a spray process
  • Automatic lifting gate
  • Also possible to use as a conveyor system in cycle operation
  • Advantages of the YukonDA:

  • High throughput
  • Extremely low handling effort
  • Individual conveyor options
  • Specially arranged spray nozzles clean hard-to-reach interior spaces

Application examples:

Automated conveyor system for cylindrical roller bearings: YukonDTK

Following the first pre-washing stage with linear movement and slight rotation of the bearings, the bearings are set to intrinsic rotation and cleaned using high-pressure water jets in the second stage. Following the fine cleaning stage and rinsing of the cleaning agent residues, the parts are intensively dried using a powerful side channel compressor.

Cleaning of bearing housings in cycle operation: OceanRW

Cleaning is carried out using a special nozzle system while the parts are rotated. To achieve the required processing capacity, the cleaning system can be loaded with two load carriers at the same time.

The bearings are moved through the cleaning system on chains in a horizontal position. Following the pre-washing stage, the parts undergo an intensive cleaning process. A cleaning lance rotates vertically around the hub of the bearing. The use of the spray bell keeps the medium within the intensive cleaning zone. Following the fine cleaning stage, the bearings are reliably dried using a high volumetric air flow and an additional blowing register.
