Proposal for a state-of-the-art sealing system to address the main challenges of V-packings. [Main Challenges] - There are instances of replacing V-packings with other types, leading to discontinuation without updating molds, making them increasingly difficult to obtain. - Lubrication is hard to reach throughout the entire V-packing, resulting in increased friction due to lack of lubrication, which leads to shaft wear. - Stick-slip is likely to occur during startup and at low speeds. - Stick-slip makes precise positioning accuracy difficult, resulting in vibrations and noise. - The design requires a large amount of space. *These main challenges can be resolved.

Hallite 831 is a single lip snap-in rod wiper. To enhance stability within the groove, ribs are formed on the inner diameter. It prevents the possibility of blowout due to trapped pressure between the wiper and rod seal. A crush lip is incorporated into the outer circumference of the seal, providing an appropriate amount of compression against the bottom surface of the wiper groove. A face piece is provided to ensure that the crush lip does not catch on the corners of the groove. These features help prevent the intrusion of contaminants into the groove. The 831 is precisely molded from Hythane 181, offering excellent wear resistance. 【Features】 ■ The design of the crush lip and face piece provides effective sealing in the wiper groove. ■ The ribs on the inner diameter release trapped pressure and improve stability. ■ Cost-effective.
