- Độ rung khi lái Nếu xe bạn bị rung lắc khi lái, đó có thể là dấu hiệu lốp bị mất cân bằng hoặc bị hư hỏng.
It is generally used in the union of two lubricated parts, so that it hermetically seals both sides. Therefore, it guarantees the proper engine operation and helps to maintain the vehicle’s distribution system in better condition.



hard rubber gasket. They can be compressed between two surfaces without losing their sealing properties, ensuring a leak-free connection. This feature is crucial in applications where a consistent and reliable seal is critical for the proper functioning of equipment.

Regular maintenance and inspection of the 25x47x7 oil seal are also important in preserving its performance over time. By checking for signs of wear or damage and replacing the seal as needed, machine operators can ensure that the seal continues to provide reliable protection against oil leaks.
However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.

4. Protecting the shaft from damage helps optimize your oil seals’ efficiency.
Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
