When choosing a fifth wheel coupling, you should especially take into consideration the requirements placed on bearing arrangements, mounting and maintenance. Basically, JOST fifth wheel couplings can be used universally.
Fifth wheel couplings with rubber mountings are particularly suitable for poor quality road surfaces. The rubber cushions are shock-absorbent and maintenance-free.
The cardanic bearing is designed to allow roll between tractor and semi-trailer under off-road conditions. Due to the high strains it is designed as pivot bearing with wear-resistant bearing bushings. The lateral suspension must be disabled for
The K-bearing moves especially easy and it is torsion-proof and maintenance-free. It protects the chassis due to its longitudinal elasticity (lateral movement).
The pivot bearing allows low mounting heights and is maintenance-free in the “E” version. It is particularly suitable for use in sliding and dual height fifth wheel systems.
The new hybrid bearing combines the advantages of the rubber and the slide bearing. The rubber cushions are shockabsorbent and maintenance-free. Thanks to the plastic collars it protects the chassis due to its longitudinal elasticity (lateral movement).
