Shroud strengthens visual pop-up indicators on filters
Schroeder Industries has released a protective shroud for the D5 series visual pop-up indicators. This shroud protects D5 indicators against harsh environments and inadvertent impacts that cause indicator cracking/breakage. Visual pop-up indicators provide an economical way to know (at a glance) when a filter element needs to be replaced. With … [Read more...] about Shroud strengthens visual pop-up indicators on filters
A review of hydraulic fluids and contamination control
It’s critical for equipment manufacturers and the engineers they employ to possess a sound understanding of the composition of oils, the properties of lubricants, and how hydraulic fluids can impact machine performance. With that fact in mind, IFPE 2020 will offer attendees an education session entitled “Hydraulic Fluid Properties, Efficiency … [Read more...] about A review of hydraulic fluids and contamination control
More desiccant and increased airflow means longer life for breathers
Des-Case has recently improved its breather designs, featuring more desiccant and increased airflow without increasing the external dimensions of the breather, which adds up to 25-50% longer breather life. Now its VentGuard, Standard and HydroGuard breathers feature the new options, including: Domed cap to allow for better washdown … [Read more...] about More desiccant and increased airflow means longer life for breathers
New rotary shaft seal coating reduces wear and shaft runout
The optimum function of rotary shaft seals depends on many factors. One of them is the wettability of the sealing lip. This parameter plays a particularly important role with synthetic lubricants such as polyglycol. If wetting is too low, not only does wear on the sealing lip increase, but the contact with the rotating shaft can also damage the … [Read more...] about New rotary shaft seal coating reduces wear and shaft runout

Setting planned and intelligent filter maintenance programs can reduce downtime, increase efficiency and usher your hydraulic systems into the IoT future. By Josh Cosford, Contributing Editor Plant maintenance practices vary by industry, by economic conditions, by process and by employees. Some plants may have strict preventive maintenance … [Read more...] about Filter maintenance 101
How do water hydraulics work?
By Josh Cosford, Contributing Editor Most of you are familiar with the use of oil as the fluid medium for hydraulic systems, which is inherently excellent at its job. It lubricates well, provides good heat capacity and is stable over various pressure and temperature ranges. As good as oil is, it’s not the only power transmission liquid in use … [Read more...] about How do water hydraulics work?
Electrically conductive PTFE-based seal materials for dynamic applications
Trelleborg Sealing Solutions has launched Turcon MC1 and Turcon MC2 materials, the only PTFE-based (polytetrafluoroethylene) electrically conductive materials suited for use in spring and elastomer-energized seals. Engineered for dynamic applications, seals and bearings from the materials will provide reliable electric connection between moving … [Read more...] about Electrically conductive PTFE-based seal materials for dynamic applications
Pressure-released wiper prevents debris from reaching critical components
ClearSeal PRW, from Seal Engineering AS, is a patented, pressure-released, internal wiper with a filter function that prevents debris in the hydraulic oil /pressure media from reaching seals, bearings and other components. It provides insurance against breakdown in hydraulic systems due to contaminated media. ClearSeal’s compact design and … [Read more...] about Pressure-released wiper prevents debris from reaching critical components
Adsorber filters protect against harmful condensation
Water in the oil is a serious issue for many hydraulic systems, because it can lead to increased wear and leakage. Adsorber filters which prevent moisture ingress via the tank breather system provide a remedy, according to engineers at HANSA-FLEX, Bremen, Germany. Unfortunately, although these filters can prevent serious damage and high … [Read more...] about Adsorber filters protect against harmful condensation
