유공압씰 Hydraulic & Pneumatic Seal — SEALSTAR

유공압씰이란 무엇인가요?What Is a Hydraulic/Pneumatic Seal?

유공압씰은 유압·공압 실린더의 피스톤과 로드가 왕복운동할 때 작동유체의 압력을 밀폐하는 직선운동용 씰입니다. 피스톤씰·로드씰·더스트씰·백업링 등으로 구성되며, 고압·내마모가 필요해 우레탄(PU)·PTFE 소재를 주로 사용합니다.A hydraulic/pneumatic seal is a linear-motion seal that contains fluid pressure as the piston and rod of a hydraulic or pneumatic cylinder reciprocate. It comprises piston seals, rod seals, dust seals and back-up rings, mainly in urethane (PU) or PTFE for high pressure and wear resistance.

작동 원리 & 구조Principle & Structure

씰은 조립 시 그루브에 예압(preload) 상태로 장착되어 무압력 상태에서도 1차 밀봉력을 갖습니다. 시스템 압력이 걸리면 유체가 씰 배면을 밀어 접촉면 압력이 함께 높아지는 자기 보강(self-energizing) 방식으로 작동해, 압력이 커질수록 밀봉력도 함께 커집니다. 로드씰은 로드를 따라 오일이 새는 것을, 피스톤씰은 피스톤과 실린더 보어 사이를, 와이퍼는 로드 표면의 이물질 유입을, 버퍼씰은 급격한 압력 피크를 각각 담당합니다.Seals are installed with a preload in the groove so they provide baseline sealing even before system pressure is applied. Once pressure builds, it pushes against the back of the seal and increases contact pressure in proportion — a self-energizing action, so sealing force scales with system pressure. Within a cylinder, the rod seal stops oil escaping along the rod, the piston seal blocks flow between piston and bore, the wiper keeps contaminants from riding in on the rod surface, and the buffer seal absorbs pressure spikes ahead of the rod seal.

주요 특징Key Features

  • 압력에 비례해 밀봉력이 커지는 자기 보강 구조Self-energizing design — sealing force increases with pressure
  • 폴리우레탄(내마모)·PTFE(저마찰)·NBR(범용) 등 용도별 소재 선택Material choice by duty: polyurethane for wear resistance, PTFE for low friction, NBR for general purpose
  • 로드씰·피스톤씰·와이퍼·버퍼씰·가이드링까지 실린더 풀세트 구성Full cylinder seal set — rod seal, piston seal, wiper, buffer seal, guide ring
  • 공압용은 저마찰·저압(최대 16bar급) 설계로 경량·고속 대응Pneumatic-specific designs use low-friction, low-pressure profiles (up to roughly 16 bar) for light, high-speed operation

자주 묻는 질문FAQ

로드씰과 피스톤씰의 차이는 무엇인가요?What's the difference between a rod seal and a piston seal?
로드씰은 로드를 따라 오일이 새는 것을 막고, 피스톤씰은 피스톤과 실린더 보어 사이를 밀봉합니다. 두 부품 모두 조합해 실린더 풀세트를 구성합니다.A rod seal blocks leakage along the rod, while a piston seal seals between the piston and the cylinder bore — together they form a full cylinder seal set.
유압실린더 씰은 왜 압력이 높아질수록 밀봉력도 커지나요?Why does hydraulic cylinder seal force increase with system pressure?
자기 보강(self-energizing) 구조로, 시스템 압력이 씰 배면을 밀어 접촉면 압력을 함께 높이기 때문입니다.It's a self-energizing design — system pressure pushes on the seal's back face, raising the contact pressure along with it.
공압용과 유압용 씰은 같은 소재를 쓰나요?Do pneumatic and hydraulic seals use the same material?
공압용은 저마찰·저압(최대 16bar급) 설계로 경량·고속에 대응하는 반면, 유압용은 고압·내마모가 필요해 우레탄·PTFE를 주로 사용해 설계가 다릅니다.No — pneumatic seals are designed for low friction and lower pressure (up to about 16 bar) for light, fast motion, while hydraulic seals need high-pressure, wear-resistant materials such as polyurethane or PTFE.
