Seals

Contributed by Xing Hong, Founder, WRKR Seal Hydraulic systems depend on reliable sealing at every connection point. When an O-ring fails in a hydraulic circuit, the consequences range from minor fluid weeping to catastrophic pressure loss, environmental contamination, and unplanned downtime that costs thousands of dollars per hour in heavy industry. Yet a significant share […]

Keeping contamination at bay and protecting cylinders in mining applications requires careful selection of hydraulic seals. By Josh Cosford, Contributing Editor Let’s just cut to the chase; mining makes for a horrific environment for seals. From incessant contamination to pressure spikes, and from exotic fluids to environmental extremes, pretty much every cause of hydraulic seal…

At this year’s CONEXPO, Hallite presented its 668 twin lip static seal, designed to maximize seal functionality and high groove stability. It is molded in Hythane 333, one of Hallite’s high-performance polyurethanes, providing easy installation and excellent low temperature performance. “The expansion in the 668 seal range, to include imperial and metric ISO grooves, comes […]

By Josh Cosford, Contributing Editor Seals are often an afterthought when it comes to designing fluid power systems, which makes sense for the majority of applications where off-the-shelf is good enough. Designers select pumps, valves, and actuators based on criteria like flow rates, valve configurations, and pressure capacities, but most of those primary components are […]

Contributed by Inderjeet Singh  • Global Product Line Director, Trelleborg Sealing Solutions From managing contamination caused by dirt and mud to helping precisely move heavy loads at construction sites, seals used in hydraulic motors, gearboxes and pumps for rotary fluid power applications face significant demands. Performance expectations for these high-pressure radial shaft seals are becoming…

By Josh Cosford, Contributing Editor Here at Higginson Equipment, we produce a line of cylinders for the dump truck industry known as EconoMAX. On any given year, we produce between 7,000 and 8,000 of these for tailgate latch, air tarp systems, and tailgate high-lift applications. Each cylinder contains a T-seal for the piston, two end […]

By Josh Cosford, Contributing Editor Let’s start by stating the obvious: seal geometries matter, or the fluid power realm would use only geometrically simple O-rings. The other two critical factors for effective seal performance are polymer composition and a machined groove to call home. However, even considering the latter, a seal geometry of the same […]

Contributed by Alan Astbury, Simulation Methods Developer, Trelleborg Sealing Solutions To achieve optimal efficiency, fluid power applications and their sealing components need good friction characteristics and long life to reduce maintenance. Engineering simulations and the experts to interpret them can result in better sealing and material recommendations, leading to faster prototyping, predictive maintenance and a […]

The use of hydraulic symbols must be comprehensive in your efforts to detail the workings of a complete hydraulic system. Hydraulic machines consist of more than pumps, valves and actuators, of course, even though they are often the stars of the show. Those stars would quickly fall into the other side of fame without components […]
