오링O-Ring
O-RING
가장 널리 사용되는 기본 밀봉 부품으로, 그루브(홈)에 장착되어 두 부품 사이의 정적·동적 누출을 차단합니다. 다양한 재질과 AS568·JIS·미터 규격을 갖춰 고정 및 운동용으로 폭넓게 사용됩니다.The most widely used sealing element, fitted into a groove to block static and dynamic leakage between two parts. Available in a wide range of materials and AS568/JIS/metric sizes for both static and dynamic use.

작동 원리 & 구조Principle & Structure
원형 단면(코드)을 링 형태로 성형한 뒤 그루브에 압축 장착하면, 오링 자체의 탄성 복원력이 접촉면을 지속적으로 눌러 유체·기체의 통로를 막습니다. 압축률(보통 15~30%)과 그루브 치수가 정확할수록 밀봉력과 수명이 안정적으로 유지됩니다.A round-section elastomer cord is molded into a ring and compressed into a groove; the O-ring's own elastic recovery keeps constant contact pressure on the mating surfaces, blocking the flow path. Accurate groove dimensions and a proper compression ratio (typically 15–30%) are what keep sealing force — and service life — stable.

오링설계O-Ring Design
오링은 사용 조건(정적/동적, 압력, 온도, 유체 종류)에 따라 그루브(홈) 설계가 달라집니다. 씰스타는 아래 기준을 바탕으로 고객 사용 환경에 맞는 그루브 설계를 지원합니다.O-ring groove design changes with the operating condition — static or dynamic, pressure, temperature and fluid type. Sealstar supports groove design tailored to each customer's environment based on the guidelines below.
정적 실링 (Static Sealing)Static Sealing
플랜지·커버 등 움직임이 없는 접합부. 압축률 약 15~30%를 권장하며, 면압을 균일하게 확보하는 것이 핵심입니다.Flanges, covers and other fixed joints. A compression ratio of roughly 15–30% is recommended, with even contact pressure across the seal.
동적 실링 (Dynamic Sealing)Dynamic Sealing
로드·피스톤 등 왕복·회전 운동부. 압축률 약 10~20%로 낮추고, 마찰과 마모를 줄이기 위한 홈 폭 여유가 필요합니다.Rods, pistons and other reciprocating or rotating parts. Use a lower compression ratio (roughly 10–20%) with extra groove width to reduce friction and wear.
백업링 적용 (Back-up Ring)Back-up Rings
고압 조건에서는 오링이 틈새로 밀려나오는 압출(Extrusion)을 방지하기 위해 백업링을 함께 적용합니다. 편측 고압에는 1개, 양측 고압에는 2개를 사용합니다.Under high pressure, a back-up ring prevents O-ring extrusion into the clearance gap — one ring for single-direction pressure, two for bidirectional pressure.
그루브 치수 산출Groove Dimensioning
그루브 폭(G)·깊이(G1)·모따기(C)·표면조도(S) 등은 오링의 선경(CS)·내경(ID)과 목표 압축률을 기준으로 산출합니다.Groove width (G), depth (G1), chamfer (C) and surface finish (S) are calculated from the O-ring's cross-section (CS), inner diameter (ID) and target compression ratio.
틈새 간격(Gap)과 압출Gap Width & Extrusion
상대 부품 사이 틈새가 넓을수록, 압력이 높을수록, 소재 경도가 낮을수록 오링이 틈으로 밀려나가는 압출 위험이 커집니다. 틈새가 크거나 고압인 경우 백업링 적용을 권장합니다.Extrusion risk rises with a wider clearance gap, higher pressure and softer material hardness. We recommend a back-up ring wherever the gap is large or pressure is high.
설치 시 유의사항Installation Guidelines
조립 전 이물질을 완전히 제거하고, 모든 리드인 모따기를 적용하며, 나사산·키홈 등 날카로운 구간은 슬리브로 보호해 오링이 손상 없이 장착되도록 합니다. 설치 중 오링을 비틀거나 굴리지 않는 것도 중요합니다.Before assembly, remove all debris, provide lead-in chamfers everywhere, and protect sharp features such as threads or keyways with an installation sleeve so the O-ring goes in undamaged. It is equally important not to twist or roll the O-ring during installation.

자주 묻는 질문FAQ
오링 압축률은 왜 중요한가요?Why does O-ring compression ratio matter?
압축률(보통 15~30%)이 부족하면 밀봉력이 약해지고, 과도하면 수명이 짧아지므로 그루브 치수에 맞춰 정확히 설계해야 합니다.Too little compression (typically 15–30%) weakens sealing; too much shortens service life — the groove dimensions must be sized precisely for the target ratio.
고압 환경에서는 오링만으로 충분한가요?Is an O-ring alone enough for high-pressure service?
고압에서는 오링이 틈새로 압출될 위험이 있어, 백업링을 함께 사용해 압출을 방지하는 것을 권장합니다.At high pressure an O-ring can extrude into the clearance gap, so we recommend pairing it with a backup ring to prevent extrusion.
AS568과 JIS 규격 오링의 차이는 무엇인가요?What's the difference between AS568 and JIS-standard O-rings?
AS568은 인치(inch) 기반 미국 표준, JIS B2401은 밀리미터 기반 국내·일본 표준으로 치수 표기 체계가 다릅니다. 기존 오링의 ID·CS를 알려주시면 해당 규격으로 매칭해 드립니다.AS568 is the inch-based U.S. standard while JIS B2401 is the millimeter-based Korean/Japanese standard — the dimension tables differ. Send us the ID and CS of your existing O-ring and we'll match it to the right standard.
