System 500, the original Unitized Wheel Hub Seal for heavy-duty vehicles, is designed for rotating hubs.
The inner section of the System 500 is secured against theshaft. The outer section, press fitted into the wheel hub,rotates together with the hub around the inner section,creating a completely enclosed seal. Dirt and water, themajor enemies of hub seals, are effectively kept at distance,whilst the lubrication of the rubber lip remains intact. Thisdecreases friction and increases seal life accordingly.

The main features of the System 500 are:
- The sealing (1) element is non-rotating, which means thatthe radial force is kept unchanged at various speeds.
- The sealing surface (2) is in close contact with the wheelhub, which gives an excellent heat transfer.
- The structure of the sealing counterface (3) has beenchosen after several thousands of test hours. The positionof the sealing lip ensures best lubrication.
- The sealing lip (4) normally has bi-directional TURBO-pattern 
- Integral prelubricated dust-sealing (5) functions.
- The protruding conical part (6) of the case deflectsheavier particles due to the centrifugal force.
- The excluding lip (5) protects against water splash andfiner particles.
- Molded distance lugs (7) automatically locate the sealingelement in the right position.
- The lugs (7) are spaced and dimensioned to ensure thesealing lip has adequate lubrication.
- The inner case (8) also protects the sealing lip from directoil spray caused by taper roller bearings.
The robust ribs (9) give:
- a firm seat on the shaft
- a smooth sliding during installation
- a positive static seal even if one of the ribs is located on a
defective shaft surface
- The compression spring (10) maintains the radial force.
The initial force exerted by the sealing element will in some applications reduce due to aging of the rubber
exposed to heat, load or chemical action. For such applications where the seal is exposed to dirty  environment, i.e. off road use, the System 500 can be equipped with an additional specially developed dirt
protection, the HRV seal.
