5. FAQ

Q: Is this metal ring important?

A: This "iron ring" is the core component of the seal, requiring extremely high-quality materials—definitely not ordinary steel as you might describe. It needs to possess extremely high hardness, wear resistance, corrosion resistance, and a certain degree of toughness.

Q:I'd like to know its material properties. Could you answer that for me?

A:I am honored to do this.This is the core sealing element. It is not ordinary steel. It requires extreme hardness, wear resistance, corrosion resistance, and some toughness.

• Primary/Premium Material: High-Chromium Cast Iron
• Common Grades: 15-3 or 20-3 High-Chromium Cast Iron (approximately 15% or 20% Chromium, 3% Carbon).
• Advantages: Extremely high hardness (HRC 60-68), excellent abrasion resistance, capable of withstanding the high pressure and gritty conditions of excavator operation.
• Manufacturing Process: After casting, the rings undergo precision grinding. The sealing face (the mirror-like surface where the two rings rub against each other) must have an exceptionally fine finish.

Q: Your explanation was very detailed; I've learned a lot. Also, I'd like to understand how it works; could you briefly describe it?

A: I'd be happy to do that.

• The two components work together:
• The two rubber O-rings are compressed, generating axial spring force.
• This force pushes the precision-ground faces of the two metal sealing rings into tight contact as they rotate against each other.
• A microscopic oil film forms between the faces, creating a dynamic seal—preventing internal lubricant from leaking out and blocking external contaminants (mud, water, grit) from entering.

Q:The material of the ring seal is a mixture of PTFE and fiberglass. What are its advantages?
A: the PTFE and fiberglass mixture creates a synergistic material that is far more capable than either component alone, offering a unique combination of strength, durability, and resistance to extreme environments.
I can explain it to you briefly in a few points, and you will understand why the prices of products of the same size vary so much.

• Combined Advantage: It has the advantages of both materials.The surface is extremely easy to clean, prevents material buildup, and allows for the easy release of substances. This is crucial for applications like food processing belts, release sheets, and architectural membranes where dirt and snow need to slide off.
• This material can withstand high temperatures and operate in lower environments, greatly improving the working life of the machine.
