Solid bushing Impact resistant steel bushing with very high surface hardness heat and corrosion resistant


  • Ferrous metal base material with lubrication grooves and special thermochemical treatment.

Tolerance details

  • Housing Ø H7
  • Shaft tolerance Based on customer’s requirement (recommended f7)

Shaft material

  • 16 MnCr5 case-hardened or 42 CrMo4V inductive hardened


  • FER-MAN®246 is a low maintenance material that is suitable for higher loads, it has high abrasion resistant and durability to avoid adhesion and seizing


  • Initial and periodical lubrication is necessary.

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.


* For higher requirements – e.g. higher temperature ranges – different materials are available in this category.

** The listed values in the material properties are valid for optimal operating conditions. By changing the conditions of application, e.g. an increase in the sliding speed or strain, these values could shift.
