Steel used in aggressive environments subjected to corrosion coupled with high wear have traditionally used electroplated “engineered” hard chrome (EHC) for surface protection. While other electroplated metals like cadmium and zinc-nickel provide good corrosion resistance, they wear off quickly, leaving the underlying steel exposed. And, in recent years, there has been a push to replace […]
Enerpac launches new high tonnage cylinders
Enerpac has launched new High Tonnage Cylinders, designed to provide superior durability and side-load (eccentric load) protection. A wide range of new features will help maintain stability, increase wear resistance and corrosion protection and provide longer service life. Key features: Nitrocarburization surface treatment improves wear resistance and corrosion protection New bearing material and added bearing […]
The ins and outs of piggy-back hydraulic cylinders
Piggy-back cylinders, as the name implies, are two opposing hydraulic cylinders mounted with the bodies on top of each other. Taking advantage of this configuration enables a longer stroke from a relatively short overall length. They’re somewhat similar to familiar telescoping cylinders, where several cylinder stages are built inside of one another, and the unit […]
Enerpac announces new high tonnage hydraulic cylinder
With increasing demand for heavier lifts in harsher environments, Enerpac has risen to the challenge with a new range of high tonnage cylinders (HTC). The Summit Edition hydraulic cylinders offer outstanding durability, longer service life, and greater side-load resistance for increased heavy lift capability. New HTC engineering includes advanced bearing and sealing technology to extend […]
What are hydraulic cylinder applications?
Hydraulic cylinders are used in countless applications. They are often seen at work in both industrial applications (including hydraulic presses, cranes, forges, and packing machines), and mobile applications (such as agricultural machines, construction vehicles, and marine equipment). They’re essential to the operation of excavators, loaders, balers, telehandlers, man-lifts, drill-rigs, and dump trucks—not to mention operating […]
Three key priorities for successful agricultural hydraulic design
Agricultural hydraulic design systems must be energy efficient, easy to operate and maintain, and of course reliable. Contributed by Carl Dyke, CD Industrial Group, Inc. Designers of hydraulic systems for agricultural machines face some difficult challenges. This is especially true for high horsepower tractors with not only steering and brake functions, but where a great […]
Self-contained electrohydraulic actuator performs powerful drive tasks without external piping
New at OTC (Offshore Technology Conference) earlier this month was a new self-contained electrohydraulic actuator from Bosch Rexroth, which reduces space and weight by eliminating external piping for heavy-duty loads. As the device demonstrated its powerful lifting capabilities (in the short clip below), Tor E. Jensen, Director Oil & Gas and Marine, Bosch Rexroth, explained how the […]
How do you safely design and use hydraulic cylinders?
Contributed by J. Eric Freimuth, Hydraulic Training Associates Many of the failures in a hydraulic system show similar symptoms: a gradual or sudden loss of high pressure, resulting in the loss of power or speed in the cylinders. In fact, the cylinder may stall under a light load or may not move at all. Often the […]
CY.PAG expands business with new hydraulic cylinder product line
CY.PAG has expanded its business through creating a new product line of hydraulic cylinders—by evolving and combining our own existing technologies. Since 1995, the company has counted among its clients some of the leading companies operating in the industrial automation sector. Its hydraulic cylinders are in accordance to standards design ISO 6020/2 – DIN 24554 and N.F.P.A – J.I.C. […]
Tie rod cylinders feature linear cushioning
ZHZ Series of tie-rod cylinders have maximum operating pressure of 160 bar, piston diameters from 25 mm to 200 mm. The DIN/ISO 6020/2 compatible cylinders feature multiple mounting options, are equipped with linear cushioning. Ground, hardened and hard chrome-plated piston rods are standard, and are equipped with Viton seal as a standard, as well. Other features include: • Tie […]
