Unplanned maintenance, downtime or a need to unexpectedly change a hydraulic filter element is not an option in any underground mining operation. Today, proper hydraulic maintenance has become even more critical because the mining industry is facing the toughest operating environment in its history. Managing both cost and improving system performance are key factors dictating […]

What are hydraulic cylinders?
What is a hydraulic cylinder? It seems like such an elementary question, especially considering the depth of fluid power related material on the various WTWH and Design World websites. However, as a person whose job deals with fluid power on the daily, even I can forget how important the fundamental lessens in hydraulics are. A […]
Newly-designed VB-2000 series solves tough control issues
Designed for cost-effective control, the newly-designed Versatile Base Series Controllers from Divelbiss Corporation provide powerful features in an open-board format. “The Versatile Base 2000 Series solves today’s tough control issues with all the advanced features needed in one product family,” said Terry Divelbiss, Company President. Adding, “Our customers asked for this solution and we delivered.” […]
Bar stock and its use in hydraulic components
Bar stock is used in various applications of fluid power, either as a mounting for other valve systems or simply for consolidation of plumbing. The bar stock itself is typically an alloy of either aluminum or ductile iron, and is manufactured in billets suitable for machining finished product. The most popular use is the bar […]
Modular transducer allows measurements up to 130 ft
Position sensing in mobile applications can be tricky, especially on large machines with long boom cylinders. Such machines often rely on cable reels and string pots, but these devices are not always reliable. They can stretch, thus require recalibration. And the elements—winds causing erratic readings and dither in the hydraulics, ice buildup preventing the wire […]
NFPA hydraulic cylinders from Ortman Fluid Power
Two series of hydraulic cylinders for NFPA mounting are available from Ortman Fluid Power, Quincy, Ill., for medium- and heavy-duty operation. The 3TH series is a heavy-duty design of tie-rod construction, rated for pressures up to 5,000 psi. They are available in with steel-bodied bores from 1.50 to 20.00 in. bores. Its robust design incorporates […]
Pump cavitation: 7 ways to avoid in mobile hydraulic systems
Pump cavitation is one of the most searched topics on fluid power, which is justified, because cavitation is unfortunately an all-too-common cause of pump failure on mobile equipment. Liquids are able to hold dissolved gasses in solution, and the gas saturation level within any liquid is dependent upon the pressure, the temperature and the type […]
Hydraulic Cylinder Mounting Options
By Josh Cosford, Contributing Editor Hydraulic cylinders are available in a variety of styles and can be mounted in numerous ways. Here’s a look at some of the most common options and their advantages and disadvantages. The venerable hydraulic cylinder is the most effective means of creating linear force in the mechanical kingdom. They are […]
Leak Detection Kit Reveals Leaks in Water/Glycol-Based Industrial Systems
The new Spectroline® OLK-402 Industrial Leak Detection Kit accurately and efficiently pinpoints leaks in water- and water/glycol-based industrial systems. It allows inspection of the entire system under all operating conditions! At the heart of the kit is the OPTI-LUX™ 400 high-intensity, violet light LED leak detection flashlight. Its high-output violet light causes dyes to fluoresce […]
Bosch Rexroth continues U.S. growth with Bethlehem, Pa. hydraulics expansion
Bosch Rexroth reiterated its commitment to “local for local” manufacturing this week, as it celebrated the grand opening of its expanded hydraulics facilities in Bethlehem, Pa. Boasting an additional 150,000 square feet, the newest facility brings the number of Bosch Rexroth buildings in the Bethlehem area to seven. Previously, the space at Broadhead Road only […]
