Dura●Tech Timing Belts

Sparks Dura-Tech urethane timing belts are designed for linear motion, conveying, and power transmission applications. The combination of a wear resistant polyurethane body, reinforced with steel or Kevlar® tension members make Dura-Tech belts ideal for the most severe requirements in all industrial applications.

Dura●Tech urethane timing belt material features.

Dura-Tech urethane timing belts are made from thermoplastic polyurethane that offers excellent abrasion resistance, impervious to oils, greases, acids and chemicals.

  • Broad temperature operating range (14 – 176 degrees F)
  • Low noise, non-marking and clean operating 
  • Withstands wet and outdoor environments, and requires no maintenance 
  • Standard color is white with special colors available, including transparent and black 
  • Special compounds are available to meet FDA requirements, provide anti-static properties, or high and low temperature requirements 

Steel tension cords come standard on Dura-Tech timing belts requiring low pre-tension and preventing elongation under normal operation for the life of the belt. Reinforcement options include:

  • High Flexibility Steel: greater resistance to flex fatigue
  • High Performance Steel: greater strength suitable for higher loads 
  • Extra High Performance Steel: designed for lifting applications 
  • Stainless Steel: recommended for wet applications
  • Kevlar®: reduces belt weight, increases flexibility, non-magnetic and non-corrosive
Dura Tech Timing Belt
Double Sided Teeth and Perforation
  • Available with double-sided teeth in most styles and pitches for applications that require power transmission on both sides.
  • Timing Belts can be perforated for vacuum applications and ground on the tooth or smooth side to accommodate special applications.
Nylon Fabric
  • Tooth side (PAZ) application reduces the coefficient of friction in slider bed applications, improves tooth engagement and reduces noise on high-speed drives
  • Smooth side (PAR) application reduces the coefficient of friction on accumulation applications
Cleats
  •  Welded or mechanically fastened (embedded steel tooth with threaded securing holes extending through the belt)
  • Mounting tooth can be full width or embedded in the existing tooth for quieter operation
Backings
  • PVC supergrip Rough Top, blue or green
  • PVC, 40 durometer Shore A, 2mm thick, blue or white (FDA)
  • Linatex, 1/16” to 3/8” thick
  • Synthetic and natural rubbers
  • Polyurethane, 70 and 85 durometer Shore A, 2mm to 10mm thick, clear
  • Polyurethane 55 durometer Shore A, 2mm to 10mm, yellow
  • Polyurethane fishbone pattern, clear
  • Polyurethane foam

Dura●Tech Pulleys

Dura-Tech pulleys are available for all Dura-Tech timing belts. Our aluminum pulleys are lightweight and come standard on all DTT and DTA series belts. Steel pulleys - with pilot bores, or bored and keyed to your specifications- and cast iron pulleys- bored to suit taper bushings- meet the rigors of tough power transmission applications and come standard on all DTI, DTH and DTS series belts. We offer a broad range of teeth options starting at 10 teeth in the smaller pitches. All Dura-Tech pulleys are made to match any belt width.

Product Range


Open End Timing Belts

Produced in standard roll lengths of 100 meters and can be supplied to any desired length. The excellent precision, dimensional stability, and high abrasion resistance make them ideal in all linear motion applications. 

Mechanical Spliced Timing Belts

A square finger joint utilizes connecting pins allowing for simple field splicing where an endless splice is impractical. Mechanical splices are suitable for most conveying applications.

V-Spliced Timing Belts

Produced from open end belts, v-splices can be produced to any length starting with a minimum length of 800mm at full tooth increments. V-spliced belts are ideal for all conveying applications where synchronization is required.

Truly Endless Timing Belts

Manufactured with endless tension cords with no splice or welding. Truly endless timing belts are ideal for power transmission applications and high load conveying applications. Available in lengths from 900mm to 22,000mm in DTT, DTA, DTI and DTH series. Short belts can also be produced from molded sleeves and are available in DTT and DTA series.
