Materials of PU Timing Belts

Polyurethane is ZZR’s preferred material for timing belts. Polyurethane covers a broad array of thermoplastic elastomers, each designed for particular applications.

PU timing belts are made from high-quality thermoplastic polyurethane, ensuring smooth operation and excellent resistance to abrasion. PU timing belts come with a variety of cord types, coatings, and/or cams to suit diverse needs.

There are two types of PU materials for belt body,  Cast Polyurethane (Molded) and Thermoplastic Polyurethane (Extruded).  Usually Cast PU is transparent, while Thermoplastic PU is white. Custom sizes, materials and color available upon request.

Cast PU before the molding is liquid, while Thermoplastic PU is solid before molding. The advantage is good temperature resistance, high strength. Wide range of hardness, can be very soft and extremely hard.

Special materials for applications demanding: low temperature, high temperature, antistatic properties or food compatibility (FDA) .

Diversity in cord options:

Tensile cord is available in Steel, Kevlar, Nylon, Stainless Steel.  

  • Steel is the standard tension member. It features mild corrosion resistance and a high spring rate.
  • Kevlar (Aramid) has excellent chemical and corrosion resistance. This non-metallic materials is available with Food Grade Polyurethane materials.
  • Stainless steel is chemical and corrosion resistance with a high spring rate and also available with Food Grade Polyurethane materials.

Coatings and Coverings

  • Nylon fabric on backside (PAR)
  • Nylon fabric on tooth side (PAZ)
  • Nylon fabric on tooth and backside (PAZ/PAR)
  • Antistatic Fabric
  • Polyurethane, Rubber and PVC, available upon request.

Special manufacturing processes:

  • Perforations
  • Cams
  • Vacuum chambers
  • Water jet
  • CNC milling and grinding

Tracking Guides Options:

K6, K8, K10, K12, K13 & K15, while custom sizes (lengths, widths and heights) are available upon request. 

Advantages:

  • Precise positioning
  • Resistant to abrasion
  • Excellent chemical durability/resistance
  • High flexibility
  • Low noise
  • Suitable for high-speed applications

PU Timing Belts are offered in the following variations:

  • Open
  • Truly endless (Flex & molded)
  • Endless with a splice
  • Mechanical linking methods (such as PinJoin, Breco DC and plastic spiral)

FAQ

  • What is the use of PU timing belt ?
    PU timing belts find application across a wide range of fields, spanning from small handheld devices and high-performance drives for woodworking machinery and construction to miniature drives and precision positioning systems.

 

  • Which is better rubber or PU belt ?
    Polyurethane timing belts have greater resistance to wear compared to rubber timing belts.
    Polyurethane timing belts demonstrate higher resistance to chemicals like acids and alkalis, with each type possessing distinct characteristics.
    As of now, polyurethane timing belts have not been able to fully replace rubber timing belts, for example, the automotive industry.

Applications
