Boost your riding experience
SKF, a leading global supplier of suspension seals

SKF, the leading global supplier of seals for automotive and two- wheel applications, has launched a new series of seals to the after- market, for motorcycle forks. Our extensive experience in the area of shock absorber seals has lead to the development of a new seal thatwill enhance the enjoyment of your ride.
Seals for motorcycle suspensions differ according to the applica- tion: oil seals and wiper rings for the front fork, usually monotube seals for the rear suspension, and special seals for the steering damper. Even though operating pressures and temperatures in motorcycles are moderate when compared to a car or truck, there are some specific factors to be considered.
Enduro or motocross forks are the most demanding applications due to a long stroke, high speed and contaminated operating con- ditions. For high performance street motorcycles, the vibration frequency can be extremely high, causing chattering. In addition, there are special dust protection requirements due to the exposed position of the fork and the absence of protective bellows. In the above applications, the rider is in direct contact with the front suspension via the handlebars. Therefore, the smoothness of fork movement is vital, as it has a considerable impact on steering behavior.

SKF fork seal kits
SKF seal kits for motorcycle forks consist of an oil seal and a wiper seal developed to achieve superior sealing performance. As a result of SKF’s extensive experience in the design and mate- rial development of seals for suspension systems, SKF has devel- oped a new self-lubricating compound. The design and performance characteristics of the sealsmade from this compound enable them to keep oil in and contaminants out of the fork, while virtually elimi- nating stick-slip and improving performance by reducing friction. To get the most out of your bike, both seals should be replaced.

Laboratory tests verified that SKF fork seals reduce friction by more than 20% and keeping it constant during the operation. Stick-slip was also reduced when compared to standard seals. Diagrams 1 and 2 show the load distribution over the stroke of the fork (spikes represent vibrations) and the value of the friction generated by the seals during operation (force) both in the case of chrome plated and hard coated rod. In field tests, riders experienced a much smoother feeling that results in better accuracy and more comfort.

The sealing system for the ultimate riding experience
The oil and wiper seals have been specially designed to provide the following benefits:
•• compatible with a wide range of original equipment and after- market oils
•• increase seal life and performance
•• enhancewater and dirt protection capability and withstand UV light
•• maintain low and constant friction in operation
•• reduce wear and air suction.

Off-road high protection fork seal kits

This kit is recommended for extrememud riding conditions. To safeguard the performance of the fork, SKF recommends replacing oil seal and dirt scraper at the same time. A worn dirt scraper can heavily contribute to reduce the oil seal life time and effectiveness in operation.

SKF is introducing a new range of fork seal kits specifically developed for heavy-duty off- road use. Based on years of experience in suspension sealing systems and on the suc- cess of the recently launched fork seal kits, this new range meets the very demanding riders’ need for more protection frommud in extreme environments.
This new kit fits most leading front sus- pension forks used on off-road motorcycles. This new generation of fork seal kit, com- posed of an oil seal and a dirt scraper, is opti- mized to enhance the protection with a dual lip dirt scraper design that creates a labyrinth to limit the exposure of the oil seals to mud to further safeguard the fork setting fromlosing his performances after short riding time.

Fork seal kits – Trial range

To safeguard the performance of the fork, SKF recommends replacing oil seal and dirt scraper at the same time. Aworn dirt scraper can heavily contribute to reduce the oil seal life time and ef- fectiveness in operation.

SKF is introducing a new range of fork seal kits – for trial bikes. Based on years of experi- ence in suspension sealing systems and on the success of the recently launched fork seal kits, this new range brings the same per- formance and endurance benefits to the more exactingworld of trial riding. This new kit composed of an oil seal and a dirt scraper provides all the benefits of our existing fork kits to deliver the ultimate rid- ing experience for the trial rider - pro or amateur. Optimized for the leading front- fork set-ups, these kits ensure low friction, limit air suction and allow consistent hy- draulic performance at factory setting levels. The scraper ensures mud and dust stay where they should – on the outside. In trial riding, where touch is everything, good feel of the front wheel is crucial to success.
