Hydraulic fluids

Selection and requirements

Hydraulic fluids must be produced, selected and used in accordance with the generally accepted rules of technology and safety. Please refer to the valid national standards and directives (in Germany, the employer's liability insurance association guideline BGR 137)

The data sheets presented here include instructions and rules for the selection, use and disposal of hydraulic fluids.

The safe and reliable operation of industrial and mobile equipment is only possible if the hydraulic fluid used is selected with respect to the application. The main tasks of the hydraulic fluid include the transmission of power, the lubrication of the components, the reduction of friction, corrosion prevention and heat dissipation.

Unfortunately, the common element “hydraulic fluid” is often disregarded during conceptual design. Increased requirements on machines and equipment constantly raise the quality requirements on the hydraulic fluid used. For selecting a suitable hydraulic fluid, adequate knowledge and experience are necessary.

For this reason, Bosch Rexroth offers the rating of hydraulic fluids for Rexroth hydraulic components as service.
