This plain bush provides a sliding contact surface based on a metal/polymer composite layer bonded to a steel backing, following the ISO 3547 dimensional standard. The steel backing gives the component its radial rigidity and stable fit in the housing bore, while the composite layer forms the actual bearing surface. Width is 40.0 mm and the net mass is 59.148 g. The design is maintenance-free, meaning no relubrication is required during operation since the polymer layer itself provides the low-friction running surface. This makes the bush suitable for applications where oscillating or rotating movement occurs under sliding conditions and where a compact radial section with a steel-backed structure is needed for load support and dimensional stability within a housing bore.
