Precision steel tubes - Ball cage

Photo of a ball cage

Precision steel tubes for ball cages (production lengths as well as short lengths) impress with outstanding surface and geometrical properties, and feature a well-defined microstructure. 

MPT commands long-standing experience in the production of precision steel tubes for ball cages and is therefore highly conversant with the special features of the products. The product portfolio includes, besides C-steels, quench and tempering steels, as well as case hardening steels. This enables us to meet a wide variety of specific customer requirements.

Customer expectations:


  • Formability, machinability
  • High surface quality
  • Adequacy for (case) hardening
  • Cross sectional volume constancy

Tube requirements:

  • Geometrical characteristics within narrow scatter bands (wall thickness, diameter, eccentricity)
  • Well-defined, homogeneous microstructure
  • Customized chemical analysis
  • Demanding requirements on the macroscopic degree of purity


If you wish, we’ll be pleased to keep you up to date by e-mail.
