Flat Belts

Welded Flat Belting

Endless Flat Belts

Advantages of Flat Belts

The flat belt has a small bending section and low bending loss. The friction engagement on the outer surface of the pulley needs only a small cross-section and makes the flat belt very flexible, resulting in negligible energy losses. Flat belts, with their grooveless design, minimize energy loss and wear, as they don’t wedge into or pull out of grooves.

Other advantages of flat belts include high productivity, long belt and pulley life, energy savings, minimal downtime and low noise from smooth belt operation. Flat belt installation is secure and simple. Tension the belt to the calculated initial tension by applying simple measurement marks on the belt. There is constant tension on the belt so there is no need to re-tension the belt.

Other advantages of flat belts include:

  • Flat belts offer simplicity, cost-effectiveness, flexibility and durability.
  • Flat belts perform more effectively at elevated speeds and offer greater cost efficiency.
  • Flat belts are capable of enduring heavy loads and have prolonged lifespan.
  • Using a flat belt drive provides smooth operation and reduces the need for repairs and maintenance.
  • Flat belts are appropriate for covering long distances.
  • Flat belts offer significant cost savings when shafts are separated by large distances.

Materials of Flat Belts

Tractions layers include Polyamide, Polyester, Aramid and Thermoplastic Polyurethane (TPU):

Polyamide are well known for its reliability and long belt life. Robust and highly resilient, copes with intermittent overload and high temperatures. The adhesive-based Thermofix joining method is available. 

Polyester are low energy consumption, highly flexible, simple to join, reliable performance. The Flexproof and/or Quickmelt adhesive-free joining methods are available.

Aramid has low energy consumption and high E-modulus. It is easy to join and highly flexible. It is a good choice for long belt, because of high accuracy and short take-up for belt speed and number of revolutions (RPM)

Polyester and Thermoplastic Polyurethane (TPU) are known for their extremely high wear resistance, excellent tear strength, high elasticity, great low temperature performance. The Flexproof and/or Quickmelt adhesive-free joining methods are available.

Power Transmission Flat Belts are customized to two main industry needs: 

1.      Textile industry (yarn processing, cards, draw frames, roving frames, ring spinning frames, OE machines, twisting machines, texturing machines, winders, overhead cleaners)

 2.      Paper and postal industry (calenders, paper mills, pulpers, slitters, web feeders, folders, finishing machines, converting lines, letter sorters)

Features of Flat Belts

  • Quiet operation
  • Exceptional flexibility
  • Grooves not needed
  • A flat belt can transfer significant power even at high speeds.
  • Long service life as they handle dust and dirt reasonably well
  • Reinforcement for greater strength
  • Superior efficiency (reaching up to 98%)
  • Minimal bending loss because of small bending cross-section


  • What are flat belts used for ?

Flat belts are used for superior performance conveying and light-duty power transmission. They are most suitable for applications requiring smaller pulleys and greater central distances. Flat belts can link between both inner and outer wheels, available in either endless or welded constructions. They offer excellent power transmission efficiency, affordability, ease of use and installation.

  • Where are flat belt drives used ?

Flat belts feature a rectangular shape and sit on top of flat pulleys to function. Flat belts can transfer power from one side or both sides according to the design. Flat belts are utilized in various industrial machinery like sawmills, water pumps, fans, compressors, separators, belt conveyors and machine tools such as grinders.

  • How much horsepower does a flat belt have ?

Flat belts have the capacity to transmit up to 150 horsepower per inch at speeds surpassing 20,000 feet per minute.

  • What is the difference between flat belts and conveyor belts ?
    • Flat belts are narrower than 100 millimeters in width.
    • Conveyor belts possess a width that is 100 millimeters or more.
  • Difference between V-Belt and Flat Belt Drives ?
    • Flat belts are usually utilized in belt conveyors, sawmills and the food sector.
    • V-belts are frequently employed in electric pumps, compressors and machinery.
