CVJ Seal Technology

• High performance materials
• Compact designs
• Integrated PTFE lined seal

Race-tec, using non-linear Finite Element Analysis (FEA) simulations, is able to offer custom designed CV seals to meet motorsport requirements. Designs can be integral to differential to reduce aerodynamic drag.

Race-tec is able to offer several methods of mounting the boot onto the hub/transmission, and retention on the shaft.

Custom design using non-linear FEA:

Performance Features

Materials

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

Race-tec has developed special formulations for Grease compatibility Reinforced grades to improve tear resistance.

Technical Features

The CV seals can be mounted on/in the hub/transmission using one of the following methods:

• Interference fit
• Mechanical retention with a custom design circlip
• Simple cable tie
• Bonded into housing

In the case of the shaft, retention can be maintained using cable tie, clamp or garter spring.

To avoid pressure build up within the CV joint, breather vents can be designed into the seal.

As shown in the example below, special designs can be configured for the ‘unsolvable’ problems.

Applications

Race-tec CV 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 high flexibility, good tear resistance, compact design etc.
