The most common questions when choosing tubes, bars, and materials for hydraulic and machining applications.
How do you choose between precision tubes and seamless steel tubes?
Precision tubes are the better fit when you need tighter dimensional tolerances, better control of the internal and external surface, and hydraulic or machining-oriented applications. Seamless steel tubes are often the better fit for broader industrial loads, boiler service, and customer-specific executions.
When should you choose hard chrome-plated bars instead of induction-hardened bars?
Hard chrome-plated bars are a practical choice for standard cylinder applications and smooth surface requirements. Induction-hardened chrome-plated or nickel-chrome bars are a stronger fit when higher wear resistance and dynamic load capacity are required.
When are calibrated round bars and scraped bars the right choice?
Calibrated round bars are useful when tighter size control and repeatability are important for machining. Scraped bars are a better fit when improved surface condition and easier downstream machining are required.
