Polyurethane Rod
Polyurethane rods are solid or hollow round PU elastomer materials for industrial and OEM use. They offer excellent wear and impact resistance and are fully machinable into rollers, bushings, seals, spacers, and precision mechanical components.
Polyurethane Rod – Solid & Cast Round PU Rod for Industrial Appliaction
Our Production Capabilities
Compared with rubber, nylon, and metal, polyurethane rods offer an excellent balance of elasticity, wear resistance, and load-bearing capacity, making them ideal for machined industrial components.
- Hardness: Shore A 30–95 (custom available);
- Manufacturing process: Cast or molded polyurethane;
- Diameter: Custom diameters available;
- Length: Cut-to-length or full-length rods;
- Color: Natural, black, or custom colors;
Applications of Polyurethane Rod and Bar
PU rods are widely machined into industrial components such as:
- Conveyor rollers and guide rollers;
- Industrial wheels and support rollers;
- Bushings, sleeves, and spacers;
- Wear pads and impact components;
- Custom OEM polyurethane parts;
