5. Principi de funcionament

Once installed, the SKF 17387 seal functions by creating a dynamic barrier between the rotating pitman arm shaft and the stationary housing. The primary sealing lip, reinforced by an internal spring, maintains constant contact with the shaft surface, preventing power steering fluid from leaking out. The auxiliary dirt lip provides an additional layer of protection, excluding contaminants like dust, dirt, and moisture from entering the system. The Bore-Tite coating on the outer diameter ensures a static seal within the housing bore, preventing external leaks.

The SKF 17387 seal is designed for long-term, maintenance-free operation once properly installed. Regular maintenance of the seal itself is generally not required. However, it is advisable to:

• Inspeccionar periòdicament: During routine vehicle maintenance, visually inspect the area around the pitman arm shaft for any signs of fluid leakage.
• Maintain Fluid Levels: Ensure the power steering fluid level is always within the recommended range for your vehicle. Low fluid levels can indicate a leak.
• Use Correct Fluid: Always use the power steering fluid type specified by your vehicle manufacturer. Incorrect fluid can degrade seal materials over time.
