잘못된 씰 크기를 주문하면 수리가 지연되고, 비용이 들고, 무엇보다도 기계를 며칠 동안 끄게 될 수 있습니다. 저는 그런 실수를 했고, 여러분이 그러기를 바라지 않습니다.

유압 씰을 올바르게 측정하려면 다음을 기록해야 합니다. 내경(ID), 외경(OD), 그리고 횡단면 폭. 적절한 맞춤을 보장하기 위해 이러한 치수는 실린더의 홈과 일치해야 합니다.

Let me walk you through how I measure seals in my daily work—and how you can avoid common errors, even without fancy equipment.

What tools do I need to measure a hydraulic seal accurately?

Without the right tools, seal measurement turns into guesswork. And guesswork leads to leaks.

In my toolbox, I always keep:

• Digital caliper (0.01 mm accuracy)
• 평면 또는 강판
• Clean cloth for oil removal
• Backup: vernier caliper
• Notepad or printable measurement form

These tools help me measure every seal—whether it’s brand new or worn beyond recognition.

도구	목적
디지털 캘리퍼스	ID, OD, and width measurement
플랫 플레이트	Ensures seal lies flat for accuracy
옷감	Wipe away residue before measuring
Seal Form	Record specs for matching and quote

If you're working with standard sizes, check out our hydraulic seal kits by size to simplify reordering.

How do I measure a worn or damaged hydraulic seal?

Measuring worn seals is tricky, but not impossible. The key is cleaning and consistency.

Here’s my step-by-step:

1. Wipe the seal with alcohol and cloth
2. Lay it flat on a smooth surface
3. Measure ID, OD, and width three times from different points

If the seal has lost shape, I average the numbers. Recently I matched a distorted seal at 45x56x7 mm—perfectly aligned with our UN 유압 씰 line.

For damaged or incomplete samples, take a clear photo with a ruler next to it and send it to us—we’ll identify the closest match fast.

Can I measure directly from the cylinder groove?

Yes—and it’s often more accurate if the old seal is missing or destroyed.

Here’s how I do it:

• 측정하다 groove width to match seal width
• 측정하다 groove ID or OD (depending on rod or piston side)
• Optionally, check groove depth for compatibility with single/double-lip seals

Groove Feature	Measurement Tool	Seal Correspondence
너비	디지털 캘리퍼스	Seal Width
지름	ID/OD Gauges	Rod or Piston Match
깊이	Depth Micrometer	Lip Fit, Seal Retention

What if I can’t identify the seal type?

Don’t worry—it happens to most professionals at some point.

Here’s what to send us:

• Clear photos of the seal (front, side, installed)
• Machine brand and model info
• All three dimensions: ID, OD, and width
• Optional: drawing or part number

We’ve matched thousands of seals for everything from forklift cylinders in Chile to mining machinery in Kazakhstan. Often, it's just about matching profiles like 케이다스, 인도, 또는 유엔.

If you're running a service team, ask us about our printable spec sheet for field techs.

How to choose the correct hydraulic seal size?

Use this checklist:

• Clean the seal completely before measuring
• Record all three dimensions: ID, OD, width
• When in doubt, measure the groove—not the seal
• If old seal is distorted, average the numbers
• Send a photo with a scale or ruler for verification

Once you’ve got the specs, match with our hydraulic seal product range or send it to us for confirmation.

결론

The right seal starts with the right measurement. A few millimeters can make or break your system. Use accurate tools, follow a step-by-step approach, and lean on suppliers like us when you're unsure.
