General / Execution
KLAAS swivel joints are rotary units built in ball races. Therefore, they can be used anywhere to transport fluid or gaseous media between two relatively movable points. KLAAS swivel joints have a turning capacity of up to 360°.

Materials / Assembly / Application
KLAAS swivel joints are made of the materials 1.7225 (42CrMo4), 1.0570 (ST52-3) and 1.4571 (X6CrNiMoTi 17-12) as standard.
They are produced internally, and they are available in nominal diameters from ND08 to ND700. Connections used for swivel joint heads which are made of carbon steel are normally made of the materials ST35.8 or C22.8.

Swivel Joint Types / Models / Connections
KLAAS swivel joint heads can be supplied in eight different models. As a result of the modular conception, the connections can be chosen optionally. In addition to the standard swivel joints, we are also manufacturer of various customized constructions which are not specified in our catalogue.

Loads / Forces

In addition to loads through internal pressure, KLAAS swivel joints absorb external radial-forces and bending moments. Even in case of applications under rough conditions, KLAAS swivel joints are characterized by the maximum possible functionality and safety.

KLAAS swivel joints are equipped with an axial working medium seal made of PTFE compound and with an external radial working seal or an external stripper to protect the swivel joint from incoming dirt. For special applications (e.g. food industry) appropriate seals are used. Should the medium contain any abrasive parts, an internal stripper will be used additionally to protect the axial working medium seal from premature wear-out. All these components are available as single spare parts or as complete sealing kits.

KLAAS swivel joints are greased with special synthetic greases suiting the operational conditions. Up to the exchange of seals KLAAS swivel joints are virtually maintenance-free. Therefore grease nipples are not included, but they can be provided on request
