Polini shaft bearings and oil seals. A top-quality set of C4 clearance bearings manufactured for Polini by the renowned manufacturer of Polini Viton & Teflon seals. The technological advances Polini has made in collaboration with a renowned seal manufacturer have resulted in the creation of the best seals in the world.

Since 2011, no better solution has been available on the market. By combining Viton (external) and Teflon (internal) materials, the best seals have been created. Their applications include both sports and tuning.

Thanks to the use of Viton, the seals are highly durable and resistant to extreme conditions. Thanks to the Teflon ring inside the seal, resistance is reduced to almost zero, resulting in significantly lower power losses.
