5. FAQ

Q: What's this rubber ? What is its name and function?

A: This is a very interesting question.The rubber you mentioned inside the Damper Assembly play a critical role. They are commonly referred to as rubber bushings, bump stops, or dust boot/buffer sleeves.

    the functions  are as follows:

• Core Function: Cushioning and Limit-Stopping
• Prevents Metal-to-Metal Impact: When the damper is compressed to its limit (e.g., when a vehicle hits a large bump or pothole), the internal piston can slam into the bottom of the damper tube. This rubber cylinder acts as a "soft cushion," absorbing the final impact energy to avoid a hard collision. This protects the damper's internal precision components (such as the piston rod and oil seal) from damage.
• Reduces Noise: Without this rubber buffer, the metal-on-metal impact at the limit position would create a loud "clunking" sound. The rubber component effectively eliminates this noise.
• Dust and Contaminant Protection: In many designs, this cylinder is hollow and encases the piston rod, extending and compressing like an "accordion cover." Its primary role is to prevent dust, mud, road grime, water, and road salt from entering the damper's interior. If contaminants get inside, they can quickly wear down the oil seal and piston rod surface, leading to fluid leaks, performance degradation, and eventual damper failure.
• Retains Grease: For components requiring additional lubrication, it can also help keep grease in the intended area.

Q: Generally speaking, what parts does a skeleton oil seal include?
A:  Okay, this is a very fundamental and important question. A standard skeleton oil seal (commonly known as an "iron shell oil seal") is a precision assembly typically composed of three main parts that work together to achieve a perfect sealing effect.

• First part : Metal skeleton. Appearance: Like the "bone" of an oil seal, buried inside the rubber, usually not visible in its entirety.
• Second part : Main lip (sealing edge).
• Third part : Self tightening spring. Position: Tighten in the spring groove below the main lip. Material: Usually stainless steel wire.

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.
