Hydraulic systems often operate in extreme conditions and are exposed to high loads. As well, many systems are expected to retain their optimal performance in extreme conditions. As a result, the filters used are a critical element of a healthy hydraulic system.
The rotary shaft seal provides hydraulic equipment with a leak-free seal, and is typically the product chosen when hydraulic lubrication fluid needs to remain in a system.
It’s just a natural occurrence for hydraulic systems to waste a large part of their energy via the circulation of fluid at constant pressure. And energy loss occurs regardless of how hard a hydraulic system has to work to complete the task at hand.
The remanufacturing of hydraulic components has certainly changed a lot over the years. In the old days, it was a common practice to repair the broken parts of a unit, using glue and welding to re-join parts, whether in the same way as before or in a new configuration.
