Hydraulics

Here’s how to eliminate instability and oscillations in hydraulic positioncontrol systems.

Hydraulic-equipment designers are finding new ways to save energy and cut equipment costs.

In oil-lubrication or hydraulic systems, it’s the small submillimeter pieces of tool steel that cut up and destroy motors, pumps, and other hardware.

Makers of stamping presses and die casters increasingly use servocontrols to boost throughput while minimizing equipment wear and tear.

Researchers at Aqueous Recovery Resources (ARR), Bedford Hill, N.Y., use fluid-pressure differential to separate oil and dirt from industrial baths. The method improves quality and extends bath life.

Less expensive than oil and environmentally friendly, water-based hydraulics deserve a closer look.

A new magnetostrictive position sensor is specifically designed to be embedded in welded and tie-rod style cylinders or similar space-limited cylinders.

Total stainless-steel (SS) proximity sensors have long been widely used as rugged transducers that won't break when you hit them.

The right chemistry minimizes operating problems and saves money.

Rotary actuators replace multiple components and function as rotating device, mounting bracket, and bearing support, all in one.

New Thermally Reactive Advanced Protection (TRAP) breathers eliminate moisture from hydraulic reservoirs.

A line of air cylinders nearly eliminates what is known as stiction; a common problem that causes pistons inside of air cylinders to stick at the beginning of a stroke.

The Pivotrol PTF4 high-capacity condensate pump is capable of pumping 40,000 lb/hr in rapid-cycling process environments and at elevated pressures and temperatures.

The A10VSO series 32 axial-piston pump is a medium pressure and made to reduce noise in stationary hydraulic systems.

These inherent metering pumps with repeatability at 99.5 % are matchbox-size. Most models include integral digital drives and displays in wash-down enclosures.
