Superior Tire & Rubber Corp. specializes in heavy-duty industrial truck casters and customized caster solutions for every challenging application. We have revolutionized the industry by introducing a patented STR Stabilizer caster that utilizes a compressive style “PolyBlock™” in electric pallet jack casters polyurethane spring design. This technology provides multiple advantages over traditional steel spring and torsional polyurethane designs. Using higher reliability, no steel creeping effect, and higher damping resulting in less rocking and more excellent cornering stability and improved adjustability, maintaining the best performance. Our casters have been exclusively selected by OEM truck design engineers to outfit the best electric pallet trucks.
Superior Tire & Rubber Corp is the vendor of choice for significant truck manufacturers and heavy equipment manufacturers to customize caster designs to their requirements and specifications. We have a catalog of casters that fit most electric pallet jacks and meet all specifications for CL-II reach truck designs. We also specialize in ultra-heavy caster applications with in-house design and manufacturing capabilities. Our extensive testing capabilities ensure both durability and environmental soundness. Our technical staff is conversant in all ASTM, ISO, and AIAG standards and methodologies, allowing us to validate and provide the best caster designs.
