The main advantages of the bearings HARP:

  1. Usage of effective seals.
  2. High accuracy in manufacturing of working surfaces of the bearing parts, as a result noise and vibration are reduced.
  3. Improved steel for bearings. For HARP ball bearings only ultra-pure with a reduced proportion of oxygen is used. This improved steel increases lifespan of the bearing and reduces fatigue failures.
  4. Optimized radius of the bearing races, that allows to increase the dynamic load capacity of bearings and, consequently, their durability.
  5. Superfinishing surface treatment. HARP ball bearings pass superfinishing machining of all working surfaces, that reduces bearings heat, improves noise and vibroacoustc performances, increases their durability.
  6. Improved ball. In HARP bearings there are used balls with a high degree of accuracy (accuracy of 5-16 degrees) to ensure noise and vibroacoustc characteristics, to increase durability.
  7. Improved roller. In HARP roller bearings the roller is applied with modified contact, which improves bearing performance.
  8. Optimized cage. Usage of massive polyamide and brass cages in the bearings, that allows to minimize noise and vibration, to increase bearing speed capability.

CRU-duplex - cylindrical double bearing for freight and passenger cars — N6 882726Е2К1MYS43 

cru.jpgIt is intended for installation in serial wagons axle-box bodies with axial load of 23.5 t/s. It replaces a pair of bearings 30 42726Е2М and 30 232726E2M, or 36-42726Е2М and 36 232726E2M. It is supplied to the consumer assembled, lubricated and assembled according to the clearances and dimensions of inner rings bore.

Usage of CRU-duplex will increase between-repairs run up to 800 thousand km, will significantly reduce failures in axle unit operation, will drastically reduce the cost for preventive maintenance and repair of bearing units and will reduce consumption of lubrication , filled in the bearings.
