Assembly

The bush should be installed into its housing with an interference fit. The preferred method for installation is freeze or shrink fitting. Alternatively, the bush may be press fitted into its housing providing care is taken to ensure correct alignment under the press to avoid damage to the bush outside diameter or housing. For thin-walled bearings a press-in guide mandrel is recommended.

Mating material

The mating material (eg shaft) hardness should be at least 100 BHN above that of the DYN bronze. It should be fine ground to a surface finish of better than 0.8Ra and for minimum wear should be better than 0.4Ra.

Machining

The machining characteristics of DYN bronzes are the same as other commercially available bronzes. Sliding surfaces should be finished by fine machining to provide a smooth surface. Fine turning is suitable for cylindrical components with reaming and broaching acceptable for smaller diameters.

Total Quality

DYN Metal is committed to quality in everything it does in the products it supplies and the service it provides. The company is accredited with BS EN ISO 9001:2000.
