Seat system with shock absorber

Faster installation times and no reworking

Previously, plain bearings from another manufacturer were used, which were milled from bar stock. However, it was difficult to maintain the required tolerances. Some of the plain bearings had to be re-milled manually in order to guarantee the correct fit. In collaboration with igus®, a customised solution was found for the seating system. The company Professional Components now uses injection moulding bearings made of iglidur® J4 material. This is particularly cost-effective and ideal for high volume. As the bearings no longer have to be re-milled and their installation has been simplified, the final costs for customers have been reduced. Professional Components is also pleased with the increased safety and performance of its product.

The seating system comes into contact with seawater, so corrosion resistance and total moisture absorption are crucial for the selection of components. The system can be subjected to shocks of up to 5g, so optimising load distribution across the bearings is important. The reduction of rotational resistance is also crucial to enable sufficient energy transfer. The system must be maintenance-free, as most users do not have tools on board to carry out repairs at sea. It was also crucial for Professional Components that the plain bearings are easy to install during the manufacturing process in order to reduce assembly costs.
