ExpaTen 2

Ideal flange connection for misaligned flange bores and / or unequal bore diameters

ExpaTen 2 is the further development of ExpaTen. This newly designed bolt can – thanks to separately adjustable conical sleeves – also be used for more pronounced offsets between the flange bores or if the bore diameters of the flange connection differ significantly. In this way, SCHAAF ExpaTen enable an optimal connection even in difficult cases.

Advantages

ExpaTen 2 is the further development of ExpaTen and thus offers all the advantages for the ideal flange connection and additionally:

  • Adjustment of position errors of bores up to 2 mm
  • Adjustment of diameter tolerances of bores up to 0.5 mm
  • No need for combined bore adaption of both flange bores when mounting
  • Cost-saving due to reduced mounting and dismounting time
  • Simple and quick installation and removal of ExpaTen 2, as well, even after years of use – nearly unlimited times
  • Reusable after removal, again and again is also warranted with ExpaTen 2 – no sparebolts required
  • 100 % positive and frictional locking at all times after assembly, no slippage of the flanges
  • Easy and quick installation and removal of ExpaTen even after years of use – almost unlimited number of times
  • Reusable after removal, repeatedly and without the need for replacement bolts
  • Torsionally and flexurally rigid connection even with shock-like changes in speed, torque or rotational and load direction
  • No more jammed or oversized bolts
