R+L HYDRAULICS GmbH has added test couplings to its product portfolio.

Testing pressure, lubrication, bleeding air and sampling oil – in a wide variety of mobile and fixed position hydraulic applications for industry, construction machinery, agricultural machinery, naval, energy and environmental technology, mechanical engineering, automobiles and rail vehicles.

is the flexible gear coupling whose typical features are two congruent hubs with crowned teeth which transamit torque by meshing with the internal toothing of a housing component. The coupling design fulfils the requirement for compensation of radial, angular and axial shaft displacements in order to relieve the neighbouring shaft bearings from non-controlled, additional loads.

have useful volumes between 3 l and 123 l. In addition to the cooling capacity of up to 2.1 kW, your advantages lie above all in the high availability of an article that is always available for storage and in the possibility of protecting your own storage capacities through the stackability of the reservoirs.

Elastic couplings reduce intermittent short-period torsional shocks by briefly storing part of this shock energy elastically. The operating temperature range is between -40 °C and up to 120 °C.

In addition to hydraulic components and drive technology products such as our couplings, we offer a wide-ranging portfolio of high-quality oil-water and oil-air heat exchangers.
