POLINI crankshaft seal kit 18x28x7/19x30x7 mm

The POLINI crankshaft seal kit 18x28x7/19x30x7 mm represents an advanced solution to ensure maximum efficiency and optimal performance in mopeds and scooters. Made from FKM (fluorocarbon rubber), these seals are designed to withstand high thermal stress, ensuring a perfect seal on both the crankshaft and the primary shafts of CVT transmissions.

The sealing lip is coated with PTFE (polytetrafluoroethylene), a feature that not only increases the product's lifespan compared to standard seals but also reduces the coefficient of friction. This means lower heat dissipation and lower temperatures during operation, thereby contributing to improved engine performance.

Initially designed for competition engines, these seals also fit perfectly on standard engines, where the reduction of friction allows for higher RPMs, thus optimizing the available power. The steel structure of the metal casing ensures robustness and reliability over time.

With dimensions of 18x28x7 mm and 19x30x7 mm, the POLINI seal kit is the ideal choice for those seeking high performance and long durability in their two-wheeled vehicle.
