Product Features
Weight Reduction – The Hard Chrome Plated Bar structure reduces the overall weight of the rod, making it suitable for high-speed or mobile applications.
Internal Passages – Allows routing of hydraulic/pneumatic lines, electrical cables, or sensors through the rod, reducing external clutter.
Improved Heat Dissipation – The hollow core can aid in cooling, especially in high-duty cycles.
Material Efficiency – Hollow Piston Bars uses less material than a solid rod while maintaining strength (depending on design).
Product Applications
Hydraulic cylinders (e.g., in construction equipment, industrial machinery)
Pneumatic systems (e.g., automation, robotics)
Specialized machinery where internal cabling or weight savings are critical
