Together with the conical X-Tapp, an assembly instruction and information on torque settings for the locking parts is supplied.

Play that has arisen in the holes on the fixing lugs is eliminated by using a conical X-Tapp. Typical objects include swing lock cylinders on machinery, swivel arms on cranes and joints on industrial equipment.


The original bolt is removed from the lugs and an X-Tapp is fitted instead directly into the enlarged fixing lugs. The holes in the fixing lugs are not filled by welding and no boring is required. With a tapered journal (basic kit), play of up to 4 mm can be rectified; if necessary, even a larger amount of play can be repaired.

When the conical X-Tapp on the casing is widened, the play is eliminated in the hole completely and permanently. A joint with an X-Tapp is easy to disassemble and reassemble, for example, if the cylinder seals need to be replaced. Conical bolts are available for almost all items.


What are conical X-Tapps most suited for?

The application area covers almost all such joints in machinery, industrial equipment and saw mills. The normal bolt diameter is 16–150 mm, but larger diameters are also possible.


Solve the problem and save money!

The X-Tapp is a simple and cost-effective solution when there is play in joints. It is fitted directly into the existing mounting lugs without costly welding and broaching.

The total costs are always lower than traditional repair methods, irrespective of the machine and model.


A profitable investment guaranteed.

The X-Tapp is profitable the first time a repair is carried out. Traditional periodic repairs and repeated maintenance costs are eliminated completely with this permanent solution. The X-Tapp is a profitable investment that pays for itself during the assembly phase.
