Why are hydraulic seals used in hydraulic rams?
Why are hydraulic seals used in hydraulic rams?
Hydraulic Seals are able to withstand high pressures, extreme temperatures and transverse forces within the cylinder. The main function for Hydraulic Seals functions goes far beyond preventing fluid leakage. They are specially engineered and can be used for Hydraulic Cylinder Seals and Hydraulic Rams.
What should I do if my hydraulic rams are leaking?
Inspect the scraper seal on top of the gland. This is a hard nylon seal which plays the important role of wiping the rod clean as it slides back into the ram. This prevents ingestion of dirt and foreign matter into the ram and hydraulic system. Replace if necessary. Inspect the condition of the piston.
How do you take oil out of a hydraulic ram?
Having fully unscrewed the gland, draw the entire rod out of the main cylinder. Any oil within the ram will flow out at this point, so have a suitable container ready to catch this oil. Take care not to mark or scratch the polished surface of the rod. There are seals sliding on this polished surface and any imperfections will quickly ruin them.
What causes oil to move between the chambers of a hydraulic ram?
There are a number of internal seals which prevent the oil from passing from one chamber to the other. When these seals fail, the oil moves between the chambers, causing unwanted linear movement in the ram. This can often be observed on an attachment like a front-end loader.

Where can I get a replacement hydraulic seal?
This depends on a lot of factors, if we keep it straight forward and say that all the parts of the hydraulic cylinder are in serviceable condition then a simple hydraulic seal replacement should do the job. You can source seals from the OEM (Genuine Seal kit) of aftermarket seals can be sourced from various different wholesalers around the world.

Where can I reassemble a hydraulic ram cylinder?
To reassemble the cylinder, simply reverse the steps. If parts need replacing, they can generally be purchased at any industrial and agri component stores. Having reassembled the ram, replace it into its working position, fit the hydraulic hoses and you’re back in action.
