• roatory motion 360      • novel EO -annular piston sealing     • low starting torque     • combined sliding and ball bearing     • self-adjusting     • EOLASTIC -sealing at the screw- in side     • favourable flow conditions     • space saving     • free of attendance     • proved in practice
• EO -pipe connection (accord. to DIN 2353)     • 8 types

The ball bearing -swivel couplings, which have been proved in practice for years and further developed in the meant5ime are an essential supplement to the EO- range of production, in order to take into account the constantly increasing demands of hydraulics. Everywhere, where hydraulic liquids have to be conducted safe against high pressure from a fixed to a roatory or pendulous part of a machine, - swivel couplings can be employed. In case of a first order it is advisable to fill in our questionnaire for-swivel couplings.

The construction of the swivel coupling is to be seen on above sectional drawing. The annular piston sealing as well as the EOLASTIC -sealing at the screw-in side made of materials, which are especially suitable for these purposes, are the innovations of this coupling. Only hydraulic oils and lubricants on mineral oil basis are suitable as mediums. With regard to the risk of corrosion we do not recommend swivel couplings for mediums containing water.

-swivel couplings are ready to be installed, provided with a permanent lubrication (grease fitting) and free of attendance; sealings and ball bearing reqire neither an adjustment nor a lubrication, therefore they are secure against unauthorized opening. Special prospectus No. 501 on demand.
