The Series NF Poly-Tech Wheels combine a contemporary aesthetic with robust functionality. These wheels feature a red polyurethane tread, known for its resilience (90-95 Durometer Shore A), securely bonded to a hard polypropylene center. This unique design offers both visual appeal and long-lasting durability.
These wheels are an excellent choice for a wide range of environments including hospitals, schools, restaurants, hotels and motels, office buildings, and light industry. Their attractive design and durable construction make them ideally suited for both aesthetic appeal and practical use in these settings.
To cater to various requirements, Poly-Tech Wheels are available with multiple bearing options: Delrin bearings, ball bearings, stainless steel ball bearings, and straight roller bearings. These options provide the flexibility to choose the perfect wheel for your specific needs, ensuring smooth operation and longevity.
The 1-3/8" wide wheels, an extension of the former Nu-Flex Series, are now available in the HL, 300, and STL series. Additionally, sizes like 4" x 2", 5" x 2", 6" x 2", and 8" x 2" are offered in our cold-forged caster series as well as in the STA and BC series, providing a comprehensive selection to meet diverse requirements.
