rexroth hydraulics- Motors, Pumps, Cylinders and Valves

rexroth hydraulics is a worldwide leading supplier of hydraulic components and systems for mobile and industrial applications. The scope of supply includes components and especially matched electronic components.

Rexroth Hydraulics Components

The Rexroth hydraulics radial piston motors and servo cylinders are some of our best products and external and internal gear pumps, vane pumps, and radial piston pumps, are some of the major components.

Cylinders and Manifolds

We have a complete line of cylinder installation and mounting types that conform to the standards ISO 6020/2, DIN 24 554, and NF E 48-016. Each cylinder is tested to our high standards, taking a nominal pressure of 160 bar and a maximum operating pressure of up to 210 bar. We also design, machine, and assemble custom manifolds.

Valves

Rexroth has mastered all three disciplines of hydraulics and apply them in their product range: Valve technology for controlling dynamically moved masses, secondary control for applications with energy recovery and hydrostatic drive hdyraulics with outstanding efficiency.

Motors

Motors take hidraulic energy and convert it into mechanical energy to turn a shaft. There are an array of different types for any application including: swashplate motors, radial piston motors, and gear motors.

Dual displacement swashplate motors provide the optimum weight and compact dimensions for specific demands. The low noise levels and wide control range make them suitable for industrial and mobile applications, in open- and closed-loop designs.

Gear motors are the most common hydraulic units. Self-priming fixed-displacement models develop very high torque and are compatible with high-pressure (up to 3600 psi) systems.Rexroth hydraulics simple and reliable design makes them suitable for industrial applications.

Pumps

A complete line of hydraulic pumps serve virtually every industry. We have bent axis pumps, swashplate pumps, radial piston pumps and vane pumps.

Bent axis pumps have the pistons at an angle to the drive shaft and thrust plate. The piston block shaft is connected to the drive shaft by a universal joint. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port.

Swashplate hydraulic pumps have a rotating cylinder containing pistons. A spring pushes the pistons against a stationary swash plate, which sits at an angle to the cylinder. The pistons suck in fluid during half a revolution and push fluid out during the other half.

Vane pumps are often used in power steering units and automatic transmissions. The vanes are in slots in the rotor. When the rotor spins, centrifugal force pushes the vanes out to touch the casing, where they trap and propel fluid. When the vanes reach the return side they are pushed back into the rotor by the casing. Fluid escapes through a channel or groove cut into the casing.
