  • compensation if there is a linear thermal extension of workpieces or if the extension is caused by the process of machining
  • run-out deviation max.: 0.01 mm incl. insert
  • easy exchange of changeable inserts using spanner flat and open-end wrench or Tommy bar
  • the adaptation of various changeables inserts ensures a high degree of flexibility and savingof costs
  • maintenance free, due to the gasket system and the lifetime lubrication filling of the bearing
  • obtaining of the axial forces applied via scale rings as well as clarification of the force ranges on the outside of the housing
