Piston Components FAQ
What piston components can you manufacture?
Engine pistons with ring grooves, compressor pistons, hydraulic pistons, piston rings and retainers, piston pins, and custom piston components. Single-off prototypes through production runs.
What materials are best for high-performance pistons?
Aluminium 6061-T6 and 7075-T6 for lightweight engine pistons. Steel 4140 for high-pressure hydraulic pistons. Titanium for racing and extreme performance. Cast iron for heavy-duty industrial.
What tolerances can you hold on piston diameters?
Piston bore tolerances held to ±0.01-0.05mm depending on application. Ring groove dimensions to ±0.02mm. Piston-to-bore clearance maintained within tight limits.
What is the typical lead time for piston components?
Simple pistons: 2–3 weeks. Medium complexity with grooves: 3–4 weeks. Custom designs with balancing: 4–6 weeks. Lead times depend on material and surface finish.
Can you manufacture custom piston designs?
Yes. Custom bore sizes, ring groove profiles, pin bore locations, and unique geometries. Engineering support available for piston optimization.
Do you offer surface treatments for wear resistance?
Yes. Hard anodising for aluminium pistons, nitriding for steel pistons, and plating for corrosion resistance. These extend piston life significantly.
