NFV – Fiberglass-reinforced Nylon. Hardness: 80 Shore D. (-40ºC to + 180ºC). Produced with fiberglass-reinforced polyamide nylon 6.6. Indicated for utilization in high and low temperature applications. They are light and have an excellent mechanical resistance, roll very easily, requiring less effort in maneuvering and handling. Resistant to greases, oils, and some kinds of acids.
NU – Molded polyurethane with Nylon Wheel Center. Hardness: 90 Shore A. (-40ºC to + 80ºC). Produced with a molded polyurethane tread and injected nylon wheel center. The mechanical bond system ensures excellent resistance and service life. Ideal for applications on various surface and environment types. They are light, withstand high loads, protect the floor, require less effort to handle and produce low noise level during handling. They have an excellent resistance to abrasion, impacts, weathering and chemicals such as greases, oils, salts and solvents. They may be used in a speed up to 4km/h.
BS – Double-Layered Molded Rubber. Hardness: 80 Shore A. (-20ºC to + 70ºC). Produced with molded double-layered vulcanized rubber tread over a grey cast iron wheel center. Ideal for external floor applications, offer a great shock and vibration absorption, high resistance to abrasion and longer service life due to their thicker rubber layer. Resistant to chemicals. They can be used at a speed of up to 20km/h when mounted with ball bearings.
