Yellow Polyurethane Hollow Rod for Construction Machinery This yellow polyurethane hollow rod is a durable PU plastic bar designed for construction machinery and related equipment. It features a hollow profile with an inner hole bore and is offered in sizes that include inner hole apertures of 8 mm, 10 mm, and 12 mm, with an outer diameter range from 18 mm to 120 mm. The example variant shown is OD 30 mm with an 8 mm hole and a length of 30 cm. Key benefits Lightweight yet robust: hollow design reduces weight while maintaining strength for moving or sliding components. Versatile fit: inner hole bore options of 8, 10, or 12 mm support throughbolts, pins, or shafts, enabling straightforward mounting and alignment. Durable PU construction: polyurethane provides good wear resistance and practical performance in demanding environments. visibility color: yellow color aids in easy identification and inspection within assemblies. Easy to work with: suitable for standard fabrication and machining processes used with PU materials. Key attributes Material: Polyurethane (PU) Type: Hollow rod / hollow bar with inner bore Outer diameter: 18–120 mm (example shown OD 30 mm) Inner hole apertures: 8 mm, 10 mm, 12 mm Length: 30 cm Color: Yellow Design: Hollow core to reduce weight while preserving structural integrity Applications Use as a guide rod or spacer in construction machinery and equipment, where a through bore accommodates pins or bolts. Serve as a lightweight bushing or wear part in sliding linkages, ramps, or actuated assemblies requiring a PU hollow profile. Ideal for prototypes, fixtures, or custom assemblies that require a lightweight PU hollow bar with precise bore sizing (8, 10, or 12 mm) and a defined 30 cm length. Notes Variants are available across the specified size range, with inner bore options and color consistent with the product line. The example variant shown is OD 30 mm with an 8 mm hole and 30 cm length.
