Sintered stainless steel parts in power tools: balancing cost and complexity

Adoption requires investment

The shift toward sintered structural parts in power tools involves clear technical advantages but significant upfront costs. Industry reports note that adoption requires substantial capital investment and workforce reskilling. This can be a barrier for smaller manufacturers. The process, however, is recognized for being cost-effective in mass production. It also supports sthe creation of parts with complex geometries that are difficult or impossible to achieve through traditional machining.

Performance in demanding applications

In power tools, which are compact motor systems, components must balance performance with cost control. Sintered bearings and bushings are common here. They support applications that depend on controlled lubrication. The continuous release of lubricating oil from an impregnated bearing helps minimise friction between surfaces. Lower friction means smoother operation, less heat, and longer component life. These bearings are also designed to withstand harsh conditions, including high temperatures and heavy loads.

Design and material selection

Proper design is essential. Technical support, like bearing calculators, can indicate if an application is within the operational range of sintered bearings. Load diagrams show it is possible to push the maximum load to higher values using the appropriate material. The best values for traditional sintered bearings are often achieved with bronze, illustrating the performance trade-offs when selecting stainless steel or other alloys for specific tool requirements.

We provide sintered structural parts and bearings suitable for these demanding power tool applications.
