A sealing ring is a circular sealing component that can be fixed on bearings or bolts, and is elastic and resilient. As a lifting equipment with hydraulic devices as the main accessories, hydraulic jacks mainly use the transmission of hydraulic oil and pressure balance within the device to complete the lifting, among which the sealing ring plays a significant role. Many people may not fully understand what such a small accessory can do. Next, we will introduce its functions to everyone.
There are many accessories for hydraulic jacks, and the sealing ring may be the least noticeable part, but it plays a significant role. It is used at the connection between the external and internal parts to prevent dust, corrosion pollutants, moisture, and other impurities from entering the air and contaminating the hydraulic oil. It can also block air, which serves as a seal. Once air enters the hydraulic device, it will reduce the efficiency of lifting, resulting in a situation where it will not rise after being pressed for a long time, and it is easy to drop when lifting.
The above is the function of the hydraulic jack sealing ring, which ensures that the equipment can be used normally. Don't underestimate it. Finally, it is recommended that users can request a set of spare jacks from the merchant when purchasing them to prevent damage and the absence of a second one for replacement.
