Fiber-reinforced composite shaft coupling.

The use of fibre-reinforced composite shafts is a major benefit for lightweight powertrains due to their low mass. The innovative Geislinger Hub connects a cylindrical solid shaft through a bolted flange and helps reduce the weight of the whole driveline. Compared to conventional hub designs, the Geislinger Hub also facilitates the design of shaftlines that are much more compact due to higher torque transmission within the same installation space.

Drawing on Geislinger’s decades of experience in fibre-reinforced composite technology, the Geislinger Hub features an outer reinforcement of the hub shell. This reinforcement ring achieves a significantly higher stiffness within the same connection dimensions while weighing less than conventional designs. This ring is made of the same reliable, high-performance material used for GESILCO® shaftlines.
