Proper blending of bent tube and hose assemblies on hydraulic systems can optimize performance and longevity.

Shock absorbers

The purpose of an energy-absorbing device is to stop a moving load with minimum load rebound, with minimum shock to the load, and minimum shock to surrounding equipment

Leakage prevention

You can make equipment more reliable and easier to maintain simply by following hose installation guidelines prescribed by manufacturers.

Hydraulic power units

By Ronald R. Gould, CFPE

A hydraulic power unit driven by an electric motor must be sized differently from one driven by an internal combustion engine - due to differences in their torque-speed curves.

In a departure from conventional wisdom, motion control can be implemented to increase production rate and product quality and consistency - all at the same time.

Rotary actuators

Rotary actuators are used to pivot a joint when a conventional cylinder mounting proves impractical due to space, weight, or motion requirements.

Reservoirs

When it comes to reservoir design, bigger is not necessarily better. In fact, the trend is to provide smaller reservoirs.

Noise control

Hydraulic systems that run without making a lot of noise do not just happen. They result from careful design and well-planned installation strategies. Here are some strategies.

Hydraulic motors

Rugged hydraulic motors transform fluid energy into rotary mechanical power, which typically is applied to a load via shaft.
