Precision steel tubes - Ball cage

Präzisionsstahlrohre für Kugelkäfige [EN]

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
