By Josh Cosford Hydraulic cylinders are used in countless machinery applications: Excavators, loaders, balers, telehandlers, cranes, man-lifts, drill-rigs, dump trucks—not to mention operating booms, arms, lifts, platforms, buckets, and platens. Hydraulic cylinders are the most effective and efficient method of pushing, pulling, lifting and lowering. Cylinders convert hydraulic energy into linear pushing or pulling mechanical […]
Hydraulic pumps in mobile machinery
By Josh Cosford There are a lot of components in a hydraulic system that are not required to achieve the result of work, but you wouldn’t get very far without a pump. The hydraulic pump is the heart of any mobile machine, converting mechanical energy to hydraulic energy, and then pumping it out into the […]
Rexroth “Tech Tip Tuesdays”: Connecting Engineers and Followers
Tech Tip Tuesdays is a Rexroth social media initiative for sharing knowledge about mechanical and electrical engineering, wind energy, hydraulics and more. In order to connect Rexroth engineers with fans and followers, the company launched Tech Tip Tuesdays via Facebook and Twitter in June 2013. Each Tuesday, a new technical tip is posted to the […]
Grippers are devices used with pick-and-place robotic systems to pick up or place an object on an assembly line, conveyor system, or other automated system. Fingered tooling—or jaws—is attached to the grippers to grip or hold the object. They come in a variety of styles and powered designs. Three common types are parallel, three-finger, and […]
What are Hydraulic Motors?
Hydraulic motors are rotary actuators that convert hydraulic, or fluid energy into mechanical power. They work in tandem with a hydraulic pump, which converts mechanical power into fluid, or hydraulic power. Hydraulic motors provide the force and supply the motion to move an external load. Three common types of hydraulic motors are used most often […]
What is a hydraulic seal?
Sealing is a vital factor in the proper function of hydraulic applications, as leakage from the cylinder or across the piston, along with the ingress of unwanted contaminants, decrease the lifespan and efficiency of the entire application. There are numerous sealing products, technologies and techniques to keep oil in and contaminants out of the hydraulic […]
Fluid power safety products
Safety is a critical aspect to any fluid power system, not just from the basic level of keeping components plumbed properly, but also in overall levels of machine safeguarding. It is critical to evaluate the entire system, including the electrical portion, to minimize exposure to unnecessary risk. Systems are rated based on the weakest link […]
What are hydraulic rotary actuators?
Hydraulic rotary actuators are used for high torque, heavy-duty motion applications. They have high force capabilities, high power-per-unit weight and volume, good mechanical stiffness, and high dynamic response. They provide the heft for lifting, turning, indexing, clamping, mixing, bending, testing, and steering applications among others. Rotary actuators are compact and efficient, and produce high instantaneous […]
What are hydraulic replacement and rebuilds?
While the hydraulic and electric industries have become more complementary to each other, they have an entirely different kind of replacement market potential, due to: duty cycle frequency of use patterns of use maintenance needs Electrical products, particularly motors, are well understood and repaired by practically every repair house across the globe. This is not […]
What are hydraulic pressure transducers?
Pressure is termed as the force per given area required to stop a fluid expanding. Pressure transducers, which are a subset of pressure sensors, can be any number of devices which sample and record the pressure in a system. A pressure transducer is unique from gauge sensing in that it converts a pressure measurement into […]
