Hub Seal Technology

• Low friction
• Ultra Narrow
• Spring loaded Teflon Lip
• Multi Lip

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 PL2 seals are used in F1 and sportscar applications. They feature two sealing lips; a spring-loaded lip in PTFE and a secondary elastomer lip for optimum performance. They are custom designed to run on soft shaft materials.

Performance Features

Materials

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

The PTFE selected may be basic “virgin” PTFE through a range of filled and special grades, which are designed and selected according to the application requirements.

Technical Features

Ultra-narrow VM-PL and VC-PL seals are 2.7 to 3.2mm wide, and enable the upright design to be reduced in the quest for performance.

VC seals feature moulded OD profiles, while VM series seals have precision machined cases in steel, aluminium, brass or titanium to match the thermal expansion properties of the mating upright housings.

The PL2 lip technology may be applied to either VM or VC style seals with an overall width of only 3.5mm.

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.
