High Performance Seals

The range of High Performance seals developed by NAK provides the customer with a range of sealing solutions to meet their demands and no longer make the seal a limiting factor in the customer's design.

Our High performance seals offer the following benefits:

• Reduced friction
• Reduced heat generation
• Reduced Fuel consumption
• Reduced shaft wear
• High pressure, speed or temperature abilities
• Extended life – Seal and mating components
• Increased power output by reducing power loss
• Increased PV Values

Designed initially for use in performance Motorsport applications such as Formula 1, GT racing, World Rally, through investment in 1997 in Race-Tec NAK a company already specialising in this field. These seals have been designed with performance in mind and have become the seals of many World Champions since. The technology is now used in the design of mainstream automotive and industrial applications where the product benefits can provide the customer with a reliable solution to a performance seal problem.

Driven by the high demands of the world-wide motorsport industry, Race-Tec has designed and developed a range of race proven and world championship winning solutions to meet the most extreme performance criteria.

Typical Motorsport applications include:

• Gearbox and Transmissions
• Upright and Hub seals
• Hydraulic Differential
• Shock Absorber
• CV Joints
• Engine

Having recognised the need to maintain fast product development for this market, and the potential for combining product and manufacturing technologies, Race-Tec joined forces with Mao Shun Oil Seals (NAK) to form Race-Tec NAK Ltd.

Customer sealing problems ultimately drive the need for continual technical development in providing innovative and effective solutions for numerous applications.

Improved performance, longer life and increased reliability are demanded from manufacturers and consumers alike. The boundaries of technology are continually pushed to meet these criteria.

Conditions such as:

• High Temperature
• High Pressure
• High Speed Capabilities
• Chemical Resistance

are the typical factors that can be accommodated into the designs and solutions of a Race-Tec NAK product.

Other factors such as low running and breakout friction, compact size, and therefore reduced weight, can lead to an increase in the output performance of the application or a decrease in the energy consumption to achieve the same performance. For a performance racing car this means extra power transmitted to the road, and for an industrial electric motor, improved efficiency with a saving in energy consumption, and possible design changes reducing manufacture costs.

In the increasingly competitive environments of motorsport and industry these factors can give your product a distinct advantage in the market.

PTFE Lined (PL) Seal Range

The Race-Tec NAK PTFE Lined (PL) seal range is a state of the art sealing technology that can be easily adapted to suit most seal styles and application conditions. It has been developed to seal efficiently while minimising friction losses and improving durability.

A layer of low friction PTFE, the same base material as Teflonâ , is bonded during the manufacturing process to an elastomer lip base. This surface forms the contact point with the shaft typically 0.2 to 0.7mm, this compared to other PTFE seal technologies which could be as much as 5 times greater.

The running friction, and more importantly, the breakout friction, can be reduced by over 40% compared to conventional seal technology. Other factors such as excellent chemical resistance, suitability for food and pharmaceutical environments, dry running ability and wide temperature range make it possible to provide a flexible and versatile package designed to suit your needs.

NAK seals are approved for use in industrial, automotive and agricultural applications world-wide, and the increasing demands of these applications is putting greater pressure on designers to meet the requirements of the consumers. Equipment is running faster and hotter than ever before, warranty and service intervals are increasing, and improved efficiency in power consumption or output is the reality of these demands.

High speed electric motors, compressors, hydraulic pumps & motors, superchargers are just a few applications that are already demanding the performance a PL seal can offer.

PL seals can not only help to solve your sealing problems but can help to enhance the abilities of your product.

Advanced and flexible manufacturing processes allow us to offer full prototyping and development support with existing and new designs, together with low production quantities that are suitable to most projects.

Also represented by stockist and distribution points world-wide allowing us to offer a complete package of design and manufacture, customer service and support.
