Differential Seal Technology

• Low friction
• Cassette style assembly
• Excellent pressure/ speed capability

Race-Tec NAK has introduced low friction, high performance seals for use with fabricated upright assemblies and wheel hub components in race car applications. The range includes VM-PL, VC-PL and the latest dual lip PL2 seals.

Race-tec NAK PL differential seals are used in F1, WRC and Paris-Dakar applications. They feature two PL pressure seals in a cassette style assembly allow oil transfer from the housing into the shaft.

Performance Features

Materials

The elastomer can be any of the common compounds, Nitrile (NBR), Hydrogenated Nitrile (HNBR), Fluoroelastomers (FKM).

In this type of application, PTFE grades are normally filled to offer maximum wear resistance whilst still minimising frictional losses.

Technical Features

The assembly is normally made of two narrow PTFE lined seals with anti extrusion supports for each seal.

These seal assemblies have successfully been used in applications using speeds up to 8,000 rpm and pressures to 40 bar.

Assembly may be welded, pressed or supplied as separate components depending on the exact application requirements.

Typical widths of differential seal assemblies are 12 – 15mm.

Applications

Race-Tec NAK seals are used in all forms of top motorsport i.e. F1, sportcars, WRC, Nascar, where the seal is custom designed to meet the performance demands of the application, whether it be ultra-low friction qualifying, low friction dirt exclusion, etc.
