A high-quality universal lip seal for 70 mm diameter pins. Its function is to protect the arm joints from external contaminants (dust, water, mud) and to keep grease inside the bushing. It is a key component that drastically extends the service life of pins and bushings by preventing their premature wear.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.
| Brand (Machine Type) | Example Application |
|---|---|
| JCB (Backhoe Loaders) | 3CX, 4CX - kingpost, arm, and bucket pins |
| JCB (Telehandlers) | Loadall - boom and attachment pins |
| JCB (Wheel Loaders) | Articulation and boom pins |
The list above is for reference. Before purchasing, we recommend verifying the dimensions on your machine.
Replacing pin seals requires dismantling heavy arm components. Always secure the arm from falling using the service lock and certified axle stands. Never rely solely on the machine's hydraulics. Use safety glasses and gloves.
The seal protects the joint from dirt and water, which act like sandpaper, destroying the pin and bushings. A damaged seal causes grease to be washed out quickly, leading to accelerated wear of the entire joint.
A damaged seal is a direct path to a destroyed pin and bushing.
The cost of a new seal is negligible compared to the cost of replacing the entire joint and re-boring the worn-out holes. Don't take the risk – order new, durable GX-AFTER seals and provide maximum protection for your pins.

No. The seal protects against contaminants but does not take up play. If there is noticeable play in the joint, it means the pin and bushings are already worn and should be replaced as a set with new seals.
2. What is the function of the metal ring inside the seal?The metal ring (or casing) provides structural rigidity to the seal and allows it to be tightly and securely pressed into its housing in the arm. The outer rubber part ensures a tight seal with the housing.
