The functioning of double lip oil seals is based on the principle of hydrodynamic lubrication. When a shaft rotates, the primary lip establishes a contact with the shaft surface, creating a micro-film of lubricant that facilitates smooth operation. This film reduces friction and wear, allowing the seal to maintain its integrity even under high-speed conditions. The secondary lip plays a crucial role in enhancing the sealing efficiency by reducing the chances of oil escaping and contaminants entering the sealed environment.

1. Dimensions The numbers can indicate the dimensions of the seal. For instance, the first number may denote the inner diameter, the second, the outer diameter, and the third could refer to the width or height of the seal. These dimensions are critical for ensuring that the seal fits perfectly within the intended assembly, thereby maximizing effectiveness.

Front hub seals are designed to create a barrier between the external environment and the internal components of the hub assembly. They help to keep lubricants inside while preventing external contaminants from infiltrating the bearings. This is vital because wheel bearings rely on grease or oil for lubrication, and any ingress of dirt or water can lead to premature wear, overheating, and ultimately, bearing failure.
