Properties

  • This material is characterised by his excellent physical properties and herefore superior to other sliding bronze alloys.
  • Tungsten carbide tips are recommendable for cutting the heavy-duty bronze 1241, althouh for smaller quantities an HSS tooling can be used. Drilling and thread cutting is more difficult than an other smoother LHG heavy-duty alloys, but nevertheless feasible.

MATERIAL PROPERTIES

TOLERANCE DETAILS

  • Housing Ø According to customers specification
  • Bushing inner-Ø after mounting According to customers specification
  • Shaft tolerance According to customers specification

SHAFT MATERIAL

  • Steel >200HB dressed to size, surface roughness ≤ Rz 4

MOUNTING ADVISE

  • Housing: Mounting bevel, min. 1,5 mm x 15-45°
  • Shaft: Mounting bevel 5 mm x 15°, edges rounded
  • The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.

MAINTENANCE

  • Oil or grease lubrication is necessary. Because of lubrication holes or grooves, lubrication clearances can be reduced to a minimum and lubricant allocation can be improved.

RANGE OF APPLICATION

  • Aircraft, carriage and crane indistries, slide support bearings amd piston bearings, pumps, valves, packing boxes, gear parts as well as in machine construction and cupping tools.

CAPTION

* The above stated material properties are valid for optimal operating conditions. Through changes of the application conditions, eg. higher sliding speed or strain, these values are subject to change.

** No stock of this bearing type, all sizes will be produced order related. Special dimensions on request.
