A seal ring for a wheel hub is a sealing component designed to prevent the leakage of lubricant and the entry of dirt, water, and debris into the hub assembly. Its function is to protect the wheel bearings and internal components, ensuring proper lubrication and long service life.
Key specifications include inner and outer diameter, thickness, material type (such as NBR, FKM, or PTFE), and compatibility with the specific hub design. Seal rings must withstand rotational movement, pressure, and environmental conditions, typically ranging from -40°C to +150°C or higher depending on application.
Replacement is necessary when the seal is worn, hardened, cracked, or leaking. Common signs include grease leakage, contamination inside the hub, or noise from the bearings. It is also recommended to replace the seal ring during wheel hub or bearing service.
Porza offers a fit guarantee option where your vehicle or technical details are checked against product specifications. This ensures the seal ring matches the correct dimensions and requirements for your wheel hub assembly.
Porza supplies high-quality sealing and hub components with fast delivery across Europe. Customers can order online or choose in-store pickup in the Netherlands, Germany, or Belgium. This ensures quick and reliable maintenance for both professional workshops and individual users.
If you select the fit guarantee, Porza verifies compatibility before shipment. If the product does not fit or meet expectations, it can be returned according to the return policy. This ensures a reliable and risk-free purchasing experience.
