Hydraulic leaks in excavators are a costly problem. I’ve seen firsthand how the right seals prevent downtime and extend machine lifespan.
Excavator hydraulic seals are essential for maintaining system pressure, preventing leaks, and protecting cylinders from wear and contaminants.
Let’s break down how to choose the right seals for your excavator.
Why Are Hydraulic Seals Critical for Excavator Performance?
Hydraulic seals:
- Prevent fluid leaks, maintaining pressure
- Block dust, debris, and water ingress
- Reduce wear & friction in cylinder components
- Ensure smooth, reliable machine operation

Which Hydraulic Seals Are Used in Excavators?
| 씰 유형 | 기능 | 가장 적합한 |
|---|---|---|
| 피스톤 씰 | Stop fluid bypassing piston | High-pressure lifting/digging |
| 로드 씰 | Prevent rod-end leakage | High-temp & aggressive fluids |
| 와이퍼 씰 | Clean rod surfaces | Muddy, dusty job sites |
| 반지 착용 | Prevent metal contact | High-load lateral support |
| O-Rings & Backup Rings | Static sealing support | Cylinder internals |

What Materials Are Best for Excavator Hydraulic Seals?
| 재료 | 온도 범위 | 최상의 사용 | 장점 |
|---|---|---|---|
| 티피유 | -40°C ~ 100°C | 로드 & 와이퍼 씰 | Flexible, wear-resistant |
| 영어: NBR (네이버) | -30°C ~ 110°C | General seals | Cost-effective, oil resistant |
| 에프케이엠 | -20°C ~ 200°C | High-temp sealing | 내열성 및 내화학성 |
| PTFE | -200°C ~ 260°C | Rod & piston seals | Extreme durability, chemical proof |
| POM | -40°C ~ 120°C | 반지를 착용하다 | 고강도, 저마찰 |
✅ 팁: For excavators, TPU & PTFE offer the best balance of wear resistance and chemical durability.
굴삭기용 유압 씰을 측정하는 방법은 무엇입니까?
Correct sizing is key to leak prevention:
- Measure Inner Diameter (ID)
- Measure Outer Diameter (OD)
- Measure Cross-Section (CS)
| 씰 유형 | ID | 오디 | CS |
|---|---|---|---|
| 로드 씰 | 50mm(50mm) | 60mm(60mm) | 5mm(5mm) |
| 피스톤 씰 | 75mm(75mm) | 85mm(85mm) | 7mm(7mm) |
| 와이퍼 씰 | 90mm(90mm) | 100mm | 6mm(6mm) |

Common Hydraulic Seal Failures & How to Prevent Them
| 실패 원인 | 방지 |
|---|---|
| 과도한 열 | Use FKM/PTFE for high-temp zones |
| Contaminants | Maintain wiper seals, replace as needed |
| Poor Installation | Always use seal installation tools |
| Fluid Incompatibility | Select chemical-resistant materials |
| Wear & Aging | Regular inspections, scheduled replacements |
