Pneumatic Expanding Shafts

Ejes Expansibles en voladizo (un punto de anclaje) de accionamiento neumático.

DX type expanding shafts have the following characteristics:

  • Made of steel or aluminium.
  • Pneumatic expansion system, with strips or keys.
  • With strips or keys, and diameters from 25 mm (1”) to 300 mm (12”).
  • Black anodized at 50 Hrc, for lasting protection. Possibility of white color, soft anodized with less protection (enquire).
  • C40/45 tempered steel (55/60 Hrc) journals that can be made to order at no extra cost.
  • DX type expanding shafts are made of aluminium with an extruded profile or may optionally be made of steel or ERGAL, a special aluminium alloy which allows an approximate increase of 30% in the shaft’s capacity without increasing its weight.

The standard shafts are fitted with vulcanised rubber strips (rubber hardness: 80Sh±5), but on request other kinds of strips are available. The journals can also be made to order; and our catalogue includes an assortment of standard versions that have been specifically designed to be used with our safety chucks and make locking easy. (enquire).

The journals can also be made to order. Standard versions that have been specifically designed to be used with our safety chucks.
