TB – Thermoplastic Rubber. Hardness: 80 Shore A. (-20ºC to + 70ºC). Produced with recyclable thermoplastic elastic rubber tread and polypropylene copolymer wheel center. They present an excellent floor protection, soft and quiet rolling, easiness to handling and maneuvering, impact resistance, have a low deformation index under load and excellent abrasion resistance. They have a good resistance to weathering and chemicals such as salts and greases. Nominal working speed is up to 4km/h.
PC – Pneumatic – Stamped Plate Wheel Center (- 20ºC to + 50ºC). Manufactured with tire and tube, with painted stamped carbon steel plates. Indicated for applications in irregular floors where handling easiness, and impact and vibration damping is required. They offer an easy maintenance, and their components can be supplied separately. Nominal working speed is up to 4 km/h.
B – Molded Rubber. Hardness: 80 Shore A. (-20ºC to + 70ºC). Produced with molded vulcanized rubber tread over a grey cast iron wheel center. They roll softly with a low noise level, absorb shocks and vibrations. They are resistant to abrasion and chemicals. They can be used at a speed of up to 20km/h when mounted with ball bearings.
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.
