  • an engine block due to its mass is clearly harder to handle this z. B. in a tool, so are the end shields of a machine, in particular electric machine, only a few 100 grams light and therefore easy to handle.
  • the insulation element has a sleeve portion, with which this insulation element is seated in the opening of the support arm. This has the advantage that, in particular in connection with further measures, a particularly long section of a bolt section of a bolt element can be insulated. According to a further aspect, it is provided that the insulation element has a disc portion which is integrally formed on the sleeve portion.
  • this disc portion can be an insulating surface between a holding block and a support arm, so that in an axial direction (with respect to a bolt shaft direction) isolation between the holding block and the support arm is possible.

  • an insulating element has a sleeve portion between the two retaining arms, but also the other insulating element. This makes it possible to keep the sleeve portions of a single insulating element relatively short (half the distance between the holding arms), so that, for example, the manufacturing step injection molding for the insulating element can be made more reliable. Then there would be only one joint between the two sleeve sections of the two insulation elements approximately in the middle of the bolt section.
