TruMotion belts use special materials and construction to produce a belt that is optimized for minimal tooth wear. The process of a belt tooth mating with a pulley tooth produces friction as the belt tooth engages and then disengages while the drive system operates. It is the face of the belt tooth that will generate heat and exhibit wear as this occurs. This results in fine dust particles that will, over time, fall from the belt at the disengagement end of the pulley. This dust can be objectionable from a cleanliness standpoint in applications such as electronic clean rooms, medical equipment, or even office products that need a clean, non marking paper path. This dust is actually a byproduct of the tooth surface wear caused by friction. So TruMotion belts have a special nylon fabric facing on the tooth surfaces that acts to minimize friction and therefore wear during engagement and disengagement with the pulley teeth. Nylon is a self lubricating plastic that offers excellent wear characteristics. A common use for nylon is in automobile speedometer gears where there is toothed contact with metal transmission gears and operating lifetimes of hundreds of millions of revolutions are required. York drive systems don’t see those kinds of stresses, but the nylon material on the face of a TruMotion belt insures a precise tooth shape for over four times longer than with standard neoprene or urethane belts. This is important if drive accuracy is critical throughout the life of the drive. And TruMotion achieves this by minimizing wear and dust, providing an exceptionally clean belt. The TruMotion belt material that surrounds the fiberglass cord is an engineered polymer that also contributes to cleanliness and precision running due to its strength and ability to firmly lock the nylon facing and cord material in place to absolutely minimize relative motion between them as the belt rotates. Yet it provides excellent flex and shock absorption to handle vibrations that occur in drive systems. TruMotion fills a unique niche when a drive design demands cleanliness or precision well beyond what an ordinary neoprene or urethane belt can provide. So if your design specification includes long belt life, high cleanliness requirements, or precision drive timing and alignment, TruMotion can help you achieve all of these.
A clean-running belt to use when dust generation or marking is a concern. Engineered to be non-marking with 78% less dust
generation than neoprene belts. Available in 2mm GT2, 3mm GT2, 3mm HTD, 5mm HTD, .080”, 1/5”, and 3/8” pitches and uses
standard timing pulleys and sprockets. Excellent for printers and other paper path applications as well as medical devices and
clean room equipment.
- – Generates 78% less dust than neoprene belts
- High flex life.
- Minimizes friction losses.
- Corrosion and abrasion resistant.
- Quieter than urethane belts.
- Operating temperature range from –40°F to 220°F (-40°C to 104°C).
A cream colored, engineered high flex plastic over hardened fiberglass cord is the basis of a TruMotion belt. Tooth surfaces have
an outer layer of nylon for lower friction, high wear resistance, and quiet operation. This produces a belt that generates only 22% of
the dust of a neoprene belt, 7 to 10 dB less noise than urethane belts, and delivers more accurate drive registration through lower
