Superior Tire & Rubber Corp. specializes in both heavy duty industrial truck casters and customized caster solutions for every challenging application.

In electric pallet jack casters, Superior Tire & Rubber Corp. has revolutionized the industry by introducing a patented STR Stabilizer caster that utilizes a compressive style “PolyBlockTM” polyurethane spring design. This technology provides multiple advantages over traditional steel spring and torsional polyurethane designs – for example; higher reliability, no steel creeping effect, higher damping resulting in less rocking and greater cornering stability, and improved adjustability which maintains the best performance. Our casters have been exclusively selected by OEM truck design engineers to outfit the best electric pallet trucks in the market.

Superior Tire & Rubber Corp is the vendor of choice for major truck manufacturers and heavy equipment manufacturer 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 ensure the best caster designs in the industry.
